Saving Yourself From Frozen Pipes This Winter

In colder climates, there’s always a chance your customer’s pipes could freeze. And frozen pipes may burst, causing serious water damage to the home. Frozen pipes can be inconvenient and a frozen water pipe is prone to bursting, which can cause costly water damage inside the home. Therefore, it’s important to prevent pipes from freezing with a bit of seasonal home maintenance.

Tending to the home’s water pipes should be on every resident’s home winterizing checklist. Consider the following ways to prevent pipes from freezing and bursting during the cold winter months.

Identify Which Pipes that are Likely to Freeze. Certain pipes and certain sections of piping are more likely to freeze than others. Pipes that run along exterior walls of the house are more apt to freeze, particularly in an older home, where the walls may not be insulated.

Pipes that run through attic crawlspaces, garages and the basement are also prone to freezing. Homeowners should also pay attention to the area where the main water supply pipe enters the home, as this area is especially prone to freezing.

It’s also important to remember that hot water pipes can freeze; it’s not just cold water pipes that must be winterized. And the air around the pipe does not need to be 32 degrees or colder; the cold travels up the pipe, allowing the water inside to freeze, causing an ice blockage and a potential pipe burst.

Insulate Water Pipes, Especially Pipes That Are Likely to Freeze. Purchase and install pipe insulation – foam tubes that can be fitted around each pipe inside the home. Pipe insulators will help to keep pipes warm, making it less likely that the pipes will freeze.

In areas that are especially prone to freezing pipes, wrap the pipes with electric heating tape, available at most home supply stores and hardware stores.

For pipes that run along exterior walls, it’s also prudent to place fiberglass insulation between the pipe and the exterior wall for added protection from cold. Extra insulation should be placed around the section of piping at the point where the water supply enters the home, as these pipes tend to freeze at a much faster rate since the cold will travel from the outdoors and along the interior pipes.

On extremely cold days, homeowners should take extra precautions to prevent pipes from freezing. One way to prevent pipes from freezing is to keep the water moving through the pipes. To keep water flowing through pipes to avoid freezing, leave several faucets turned on, with a flow that’s just slightly more than a heavy drip. It’s important to leave several different faucets running, as sections of piping can freeze, cutting off the water supply to entire sections of the home (i.e. the entire second floor). Leaving several faucets running will also pull in more water though the main pipe running into the home – the pipe that is most likely to freeze in many homes.

There is also new eco-friendly innovative technology on the market to prevent pipe freeze that is easy to install (not requiring pipe cutting or electrical wiring) and provides instant hot water. A temperature controlled thermal convection powered hot water recirculation valve installed at the plumbing fixture at the end of the “at risk plumbing run” (pipes most likely to freeze). The Hot Water Lobster Instant Hot Water Valve will allow water to flow from your water heater-through the existing hot water pipe in the “at risk plumbing run”-to the recirculation valve. From the hot water recirculation valve the water will continue back to the water heater (for reheating)-through the cold water pipe in the “at risk plumbing run”. To save hot water the system contains a sensor, which opens the valve only when the water temperature drops below the adjustable temperature setting. This open loop of water circulation keeps temped water circulating through the “at risk plumbing run” without wasting water.

In addition, if a home loses heat for any reason (or in the case of a seasonal home), it’s important to drain the water pipes in the home to prevent the pipes from freezing and bursting. Pipes will burst as a result of the expansion that occurs when water freezes into ice.

Draining the water from a home’s pipes is simple: turn off the home’s water supply using the main valve, usually located at the point where the water supply enters the home. Then, run all of the home’s faucets and showers until the water stops flowing.

Homeowners can also prevent pipes from freezing and bursting by draining the pipes that feed exterior water spigots. Similarly, turn off the valve that supplies water to the outdoor water spigots and open the spigot and let all of the water flow out of the pipes. This should be done in fall, during the home winterizing process.

Prevent Your Pipes From Freezing:

The best solution to preventing your pipes from freezing is to simply install innovative and patented technology known as a “temperature controlled hot water recirculating valve” (is a breeze-no pipe cutting, soldering or electrical connections). It uses your existing water pipes and the thermal convection generated by your water heater to circulate the water back to your water heater for reheating (not requiring a pump or any electricity). These systems are temperature-controlled and are easily adjustable to meet your particular temperature needs. There is no water waste and it also reduces the energy required to heat your water while it provides instant hot water to your faucets and showers. A trickle of water circulating in your pipes will keep your pipes from freezing in most circumstances.

Best Ways to Prevent Pipe Freezing Next Winter

When water freezes, it expands…like a can of soda explodes if it’s put into a freezer to chill quickly and forgotten. When water freezes in a pipe, it expands the same way. If it expands enough, the pipe bursts, water escapes and serious damage results.

Why Pipes Burst

Surprisingly, ice forming in a pipe does not typically cause a break where the ice blockage occurs. It’s not the radial expansion of ice against the wall of the pipe that causes the break. Rather, following a complete ice blockage in a pipe, continued freezing and expansion inside the pipe causes water pressure to increase downstream — between the ice blockage and a closed faucet at the end. It’s this increase in water pressure that leads to pipe failure. Usually the pipe bursts where little or no ice has formed. Upstream from the ice blockage the water can always retreat back towards its source, so there is no pressure build-up to cause a break. Water has to freeze for ice blockages to occur. Pipes that are adequately protected along their entire length by placement within the building’s insulation, insulation on the pipe, heating, or water movement within the pipe are safe.

Regional Differences

Generally, houses in northern climates are built with the water pipes located on the inside of the building insulation, which protects the pipes from subfreezing weather. However, extremely cold weather and holes in the building that allow a flow of cold air to come into contact with pipes can lead to freezing and bursting.

Water pipes in houses in southern climates often are more vulnerable to winter cold spells. The pipes are more likely to be located in unprotected areas outside of the building insulation, and homeowners tend to be less aware of freezing problems, which may occur only once or twice a season.

Pipes in attics, crawl spaces and outside walls are all vulnerable to freezing, especially if there are cracks or openings that allow cold, outside air to flow across the pipes. Research at the University of Illinois has shown that “wind chill” (the cooling effect of air and wind) that causes the human body to lose heat, can play a major role in accelerating ice blockage, and thus bursting, in water pipes.

Holes in an outside wall where television, cable or telephone lines enter can provide access for cold air to reach pipes. The size of pipes and their composition (e.g., copper or PVC) have some bearing on how fast ice forms, but they are relatively minor factors in pipe bursting compared with the absence of heat, pipe insulation and exposure to a flow of subfreezing air.

When is it Cold Enough to Freeze Pipes?

When should homeowners be alert to the danger of freezing pipes? That depends on how well your pipes are protected from the cold. The “temperature alert threshold” is 20°F or below.

This threshold is based upon research conducted by the Building Research Council at the University of Illinois. Field tests of residential water systems subjected to winter temperatures demonstrated that, for pipes installed in an unconditioned attic, the onset of freezing occurred when the outside temperature fell to 20°F or below.

This finding was supported by a survey of 71 plumbers, in which the consensus was that burst-pipe problems began to appear when temperatures fell into the teens. However, freezing incidents can occur whenever the temperature is 32° F. ore below. Pipes exposed to cold air (especially flowing air, as on a windy day) because of cracks in an outside wall or lack of insulation are vulnerable to freezing at temperatures above the threshold. However, the 20°F “temperature alert threshold” should address the majority of potential burst-pipe incidents in homes.

Mitigating the Problem

Water freezes when heat in the water is transferred to subfreezing air. The best way to keep water in pipes from freezing is to slow or stop this transfer of heat.

Ideally, it is best not to expose water pipes to subfreezing temperatures, by placing them only in heated spaces and keeping them out of attics, crawl spaces and vulnerable outside walls. In new construction, proper placement can be designed into the building.

In existing houses, a plumber may be able to re route at-risk pipes to protected areas, although this may not be a practical solution. If the latter is the case, vulnerable pipes that are accessible should be fitted with insulation sleeves or wrapping (which slows the heat transfer), the more insulation the better. It is important not to leave gaps that expose the pipe to cold air. Hardware stores and home centers carry the necessary materials, usually in foam rubber or fiberglass sleeves. Better yet, plumbing supply stores and insulation dealers carry pipe sleeves that feature extra-thick insulation, as much as 1” or 2” thick. The added protection is worth the extra cost.

Cracks and holes in outside walls and foundations near water pipes should be sealed with caulking to keep cold wind away from the pipes. Kitchen and bathroom cabinets can keep warm inside air from reaching pipes under sinks and in adjacent outside walls. It’s a good idea to keep cabinet doors open during cold spells to let the warm air circulate around the pipes. Electric heating tapes and cables are available to run along pipes to keep the water from freezing. These must be used with extreme caution; follow the manufacturer’s instructions carefully to avoid the risk of fire, and check to make sure the product conforms to UL 2049. Tapes and cables with a built-in thermostat will turn heat on when needed. Tapes without a thermostat have to be plugged in each time heat is needed, and may be forgotten.

Letting the Water Run

Letting a faucet drip during extreme cold weather can prevent a pipe from bursting. O opening a faucet will provide relief from the excessive pressure that builds between the faucet and any ice blockage (if freezing occurs). If there is no excessive water pressure, there is no burst pipe, even if the water inside the pipe freezes.

A dripping faucet wastes some water, so only pipes vulnerable to freezing (ones that run through an unheated or unprotected space) should be left with the water flowing. The drip can be very slight. Even the slowest drip at normal pressure will provide pressure relief when needed. Where both hot and cold lines serve a spigot, make sure each one contributes to the drip, since both are subjected to freezing. If the dripping stops, leave the faucet(s) open, since a pipe may have frozen and will still need pressure relief.

There is new innovative technology on the market that is easy to install (not requiring pipe cutting or electrical wiring) and a great pipe freezing prevention aid. A eco-friendly temperature controlled thermal convection powered hot water recirculation valve installed at the plumbing fixture at the end of the “at risk plumbing run” (pipes most likely to freeze). The Hot Water Lobster Instant Hot water Valve will allow water to flow from your water heater-through the existing hot water pipe in the “at risk plumbing run”-to the recirculation valve. From the hot water recirculation valve the water will continue back to the water heater (for reheating)-through the cold water pipe in the “at risk plumbing run”. To save hot water the system contains a sensor, which opens the valve only when the water temperature drops below the adjustable temperature setting. This open loop of water circulation keeps temped water circulating through the “at risk plumbing run” without wasting water while it also provides instant hot water. In addition you save water and save energy.

The Hottest News On Instant Hot Water

Hot water recirculation for domestic water systems is created a lot of buzz these days, spurred primarily by consumer desire to reduce utility costs and the demand for instant hot water at the tap.

Houses are getting bigger, featuring master baths with giant tubs located farther from the hot water source. But, it’s wasteful to let all that water go down the drain, even if it is the drain of a shower with six heads.

Statistics promoted by the manufacturers of hot water recirculation systems show that the technology saves up to 17,000 gallons of water each year for an average family of four. In larger homes, with more faucets and showers and longer water lines between the water heater and distant bathrooms, the amount of water that’s wasted can be higher. But most consumers also enjoy the benefit of comfort and convince.

A recirculation system saves money in other ways. Water systems use electricity to pump water to it’s destination. The wasted water unnecessarily burdens the sewer system or septic system.

Many consumers, after spending several hundred dollars on tank-less water heaters are disappointed to find that they still have a long wait before hot water reaches their shower or faucet. However, they could have saved that money by installing a new innovative technology to provide hot water recirculation that saves water, saves energy, is convenient to use and easy to install (not requiring pipe cutting or electrical wiring). Now the eco-friendly Hot Water Lobster Instant Hot Water Valve is available. It is typically used on retrofits but may also be installed on new construction. It consists of a temperature controlled thermal convection powered hot water recirculation valve installed under the plumbing fixture farthest from the water heater. To save hot water, this eco friendly system contains a sensor, which opens the valve only when the water temperature drops below the adjustable temperature setting providing faster hot water to all your plumbing fixtures.

Domestic Water Conservation Review

In 1990, 30 states in the US reported ‘water-stress’ conditions. In 2000, the number of states reporting water-stress rose to 40. In 2009, the number rose to 45 and is expected to hit 49 in this year. There is a worsening trend in water supply nationwide. Taking measures at home to conserve water not only saves you money, it also is of benefit to the greater community.

Saving water at your customer’s homes does not require any significant cost outlay. Although there are water-saving appliances and water conservation systems such as rain barrels, drip irrigation and on-demand water heaters which are more expensive, the bulk of water saving methods can be achieved at little cost. For example, 75% of water used indoors is in the bathroom, and 25% of this is for the toilet. The average toilet uses 4 gallons per flush (gpf). You can invest in a ULF (ultra-low flush) toilet which will use only 2 gpf. But you can also install a simple tank bank, costing about $2, which will save .8 gpf. This saves 40% of what you would save with the ULF toilet. Using simple methods like tank banks, low-flow showerheads and faucet aerators you can retrofit your home for under $50.

By using water-saving features you can reduce your in-home water use by 35%. This means the average household, which uses 130,000 gallons per year, could save 44,00 gallons of water per year. On a daily basis, the average household, using 350 gallons per day, could save 125 gallons of water per day. The average individual, currently using 70 gallons per day, could save 25 gallons of water per day.

When buying low-flow aerators, be sure to read the label for the actual ‘gpm’ (gallons per minute) rating. Often, the big box retailers promote “low-flow” which are rated at 2.5 gpm, which is at the top of the low-flow spectrum. This may be needed for the kitchen sink, but we find that a 1.5 gpm aerator works fine for the bathroom sink and most water outlets, delivering the same spray force in a comfortable, soft stream.

The average family can waste over 17,000 gallons of fresh water each year while it runs down the drain as you wait for hot water to arrive (according to G.A.M.A. statistics). Install innovative and patented technology known as a “temperature controlled hot water recirculating valve” (is a breeze-no pipe cutting, soldering or electrical connections). It uses your existing water pipes and the thermal convection generated by your water heater to circulate the water back to your water heater for reheating (not requiring a pump or any electricity). To save hot water and save energy the Hot Water Lobster Instant Hot water Valve in an eco-friendly hot water recirculating systems is temperature controlled and easily adjusts to meet your particular temperature needs. These devices not only save hot water, there is no water waste and they also reduces the energy required to heat your water while it provides faster hot water to your faucets and showers for better water conservation.

Finally, it should be noted that installing low-flow aerators, showerheads, tank banks and other water-saving devices usually is a very simple operation which can be done by the homeowner and does not even require the use of tools. Water conservation at home is one of the easiest measures to put in place, and saving water should become part of everyday family practice.

Analyzing Hot Water Recirculation Systems

To help save hot water, consider a hot water recirculation system is a plumbing system that moves hot water to fixtures quickly for faster hot water so there is no need to wait for the water to get hot. Rather than hot water cooling (common in most water lines), recirculating systems circulate the water between the water heater and fixtures providing instant hot water when your customers want it.

SYSTEM TYPES:

  • dedicated loop: The hot water pipe is installed in a loop throughout the home, passing near each plumbing fixture. At each fixture, a short pipe connects the loop to the hot water valve. Because hot water is constantly circulating through the hot water loop, any time a valve is opened, it takes only a fraction of a second for hot water to reach the valve.
  • In this system, hot water is re-circulated intermittently. Hot water is returned to the water heater via the cold water pipes. This raises the temperature of the cold water slightly, but it returns to the usual cold temperature in a short time.

DO THEY REALLY SAVE ENERGY AND WATER?

Regardless of whether they are controlled manually or automatically, recirculation systems reduce the amount of water that goes down the drain while the homeowner waits for the desired temperature. This fact allows for the following three advantages over conventional water distribution systems:

  • They save time. Recirculating systems deliver hot water to faucets quickly, adding convenience for the homeowner.
  • They conserve water. According to statistics from the U.S. Department of Energy and the U.S. Census Bureau, between 400 billion and 1.3 trillion gallons of water (or close to 2 million Olympic-sized swimming pools) are wasted nationally by households per year while waiting for water to heat up.
  • They limit municipal energy waste. The DOE estimates that 800 to 1,600 kilowatt-hours per year are used to treat and pump the water to households that will eventually be wasted while the occupant waits for tap water to warm to the desired temperature.

If recirculation systems (using electrical pumps) operate continuously they have the potential to use significantly more energy. For a modest-sized pump, this might be 400 to 800 KWH a year if the pump runs all the time. Also, heat loss from the pipes can be significant if the hot water pipes are poorly insulated. However, substantial energy can often be saved by reheating the already pre-warmed (re-circulated) water instead of heating cold ground temperature water (which would normally be supplied to your water heater without a recirculation system).

REBATES:

Some jurisdictions, particularly in areas where water is scarce, offer rebates on the purchase and installation of hot water recirculation systems. The cities of Santa Fe and Albuquerque, New Mexico, for instance, offer a $100 rebate for homeowners who purchase a hot water recirculation system. The city of Scottsdale, Arizona, offers up to $200 for residential property owners who install theses systems.

AVAILABILITY AND COST:

Hot water recirculation systems are available nationwide from manufacturers, distributors, plumbing wholesale supply warehouses, and at selected retail home stores. The initial cost of dedicated systems may prevent some homeowners from installing these systems, as they require the purchase and installation of a pump and a large amount of piping. Integrated systems, by contrast, are less costly and much easier to install. Energy savings will vary, depending on the design of the plumbing system, method of control and operation, and homeowner use.

INSPECTION CONSIDERATIONS:

Dedicated return line systems require an in-line air valve and shut-off valve. Other requirements will vary with the installation’s configuration, but may include a check valve and an additional shut-off valve. The pump may be connected to a timer so that the pump circulates water through the loop only at desired times (which limits instant hot water comfort and water savings). Inspections should be limited to the system’s proper operation.

IN SUMMARY:

Hot water redistribution systems are innovative plumbing systems that provide instant hot water, can save water, save energy and prevent pipe freezing.

Heat Up Your Showers With Hot Water Recirculation!

Many people wait for hot water each morning before showering. A similar thing happens when people operate other sinks, dishwashers and washing machines. Fortunately, this problem can be solved with new technology that provides faster hot water.

This innovative new technology provides hot water recirculation valve that saves water, saves energy, is convenient to use and easy to install (not requiring pipe cutting or electrical wiring). This system is typically used on retrofits but may also be installed on new construction. It consists of an eco-friendly temperature controlled thermal convection powered hot water recirculation valve installed under the plumbing fixture farthest from the water heater. The Hot water Lobster Instant Hot Water Valve contains a sensor, which opens the valve only when the water temperature drops below the adjustable temperature setting (to save hot water).

To get instant hot water (as often found at hotels and other institutions), normally you would need to have a dedicated loop in the piping system that circulates hot water back to the water heater. Most houses do not have a dedicated loop (the hot water pipe typically dead ends at the plumbing fixture that is farthest away from the heater). It difficult to install an effective dedicated return loop in an existing home due to the proximity of pipes (behind walls, under floors, in attics and etc.).

But, you don’t have to install a dedicated return loop if you choose to use a modern recirculating system. Better systems employ an adjustable temperature actuated valve that connects the cold and hot water supply lines at the fixture that is farthest away from the water heater. The bypass valve uses the cold water line as the return loop back to the water heater and as an added benefit aids in preventing pipes from freezing.

Not all hot water recirculation systems are the same. Some systems require pumps, start buttons and timers. The systems that use pumps, timers and pushbuttons can not only be difficult to install and noisy, they also require pump replacement every 2-4 years…the most convenient hot water recirculating systems (with the best warranty) are pump-less.
