Instant Hot Water Valve
SAVE WATER! At ONLY $179.95, the eco friendly Hot Water Lobster Instant Hot Water Valve provides
faster hot water which saves water, saves energy and saves time. How long does it take for hot water
to get to your faucet or shower? A lot of precious water is wasted down the drain while waiting for hot
water. Even worse is the cost to heat the cold replacement water, which enters your house at the cold
HOW IT WORKS! When the water in your hot water pipe and the Hot Water Lobster control valve cools
below the user adjustable temperature (77-140 F. degrees), the thermal materials within the Hot
Water Lobster control valve contract and silently open the valve. Thermal convection within your hot
water tank naturally circulates the cooled water through your existing cold water pipes and back to
the hot water tank for reheating. Your existing hot water tank now uses less energy reheating the
warm water instead of cold ground temperature water. When fresh hot water enters your hot water
pipe and reaches the Hot Water Lobster control valve, the valve automatically closes. This maintains
hot water at the control valve without wasting water or wasting energy. Turn on your faucet or shower;
and you get instant hot water instead of wasting it down the drain! Installing the Hot Water Lobster
instant hot water control valve at the fixture furthest from your hot water tank (as shown in the
installation diagram) will provide faster hot water to all of the fixtures in your house.
NO ELECTRICITY NECESSARY! The Hot Water Lobster is all mechanical and designed to provide an
electricity free solution to maintain hot water at the tap. This makes installation a snap (in less than
10 minutes). Other hot water solutions require the use of electricity and pumps that make installation
difficult and the pumps are often noisy and wear out in 2-4 years.
MORE HOT WATER! Adds as much as 10% more capacity to your current hot water system (by
keeping the water in your hot water pipes hot!).
KEEP PIPES FROM FREEZING! The Hot Water Lobster instant hot water valve automatically allows
water in your pipes to circulate when the control valve cools below the set temperature (even when
your electricity goes out).
REDUCES CONDENSATION! The Hot Water Lobster instant hot water valve reduces condensation on
pipes and toilets basins.
MAINTENANCE FREE! The Hot Water Lobster has a solid brass valve body with an adjustable thermal
controlled mechanical stainless steel valve stem enclosed in a mounting box.
EASY INSTALLATION! The Hot Water Lobster comes complete with the mounting box, 4 sets of 12"
flexible water lines and standard brass fitting. All pre-assembled and tested for an easy 10-minute
STATISTICS! *A typical family wastes approximately 12,000-17,000 gallons of water annually waiting
for warm water to reach the tap. *as determined by GAMA (Gas Appliance Manufactures Association)
Note: Circulation of water by thermal convection must not be restricted (no check-valves) between the
hot water tank and the Hot Water Lobster Instant Hot Water Valve.

Are Your Pipes Likely To Freeze This Winter?
Water has a unique property in that it expands as it freezes. This expansion puts
tremendous pressure on whatever is containing it, including metal or plastic pipes. No
matter the “strength” of a container, expanding water can cause pipes to break. Pipes
that freeze most frequently are those that are exposed to severe cold, like outdoor
hose bibs, swimming pool supply lines, water sprinkler lines, and water supply pipes in
unheated interior areas like basements and crawl spaces, attics, garages, or kitchen
cabinets. Also, pipes that run against exterior walls that have little or no insulation are
also subject to freezing.
Pipe freezing is a particular problem in warmer climates where pipes often run through
un-insulated or under-insulated attics or crawl spaces. Before the onset of more cold
weather, prevent freezing of these water supply lines and pipes by following these
1. Drain water from swimming pool and water sprinkler supply lines following the
manufacturer’s or installation directions. Do not put antifreeze in these lines unless
directed. Antifreeze is environmentally harmful, and is dangerous to humans, pets,
wildlife, and landscaping.
2. Remove, drain, and store hoses used outdoors. Close inside valves supplying
outdoor hose bibs. Open the outside hose bibs to allow water to drain. Keep the
outside valve open so that any water remaining in the pipe can expand without cause
the pipe to break.
3. Check around the home for other areas where water supply lines are located and
are in unheated areas. Look in the basement, crawl space, attic, garage, and under
kitchen and bathroom cabinets. Both hot and cold water pipes in these areas should be
insulated. A hot water supply line can freeze just as a cold water supply line can freeze
if the water is not running through the pipe and the water temperature in the pipe is
4. Consider installing specific products made to insulate water pipes like a “pipe sleeve”
or installing UL-listed “heat tape,” “heat cable,” or similar materials on exposed water
pipes. Many products are available at your local building supplies retailer. Pipes should
be carefully wrapped, with ends butted tightly and joints wrapped with tape. Follow the
manufacturer’s recommendations for installing and using these products.
Take Additional Action During Cold Weather:
1. Keep garage doors closed if there are water supply lines in the garage.
2. Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the
pipes. Be sure to move any harmful cleaners and household chemicals up out of the
reach of children.
3. When the weather is very cold outside, let the cold water drip from the faucet served
by exposed pipes. Running water through the pipe – even at a trickle – helps prevent
pipes from freezing because the temperature of the water running through it is above
4. Keep the thermostat set to the same temperature both during the day and at night.
temporarily suspending the use of lower nighttime temperatures, you may incur a higher
heating bill, but you can prevent a much more costly repair job if pipes freeze and burst.
5. If you will be going away during cold weather, leave the heat on in your home, set to
a temperature no lower than 55ºF.
To Thaw Frozen Pipes:
If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Locate the
suspected frozen area of the water pipe. Likely places include pipes running against
exterior walls or where your water service enters your home through the foundation.
1. Keep the faucet open. As you treat the frozen pipe and the frozen area begins to
melt, water will begin to flow through the frozen area. Running water through the pipe
will help melt more ice in the pipe.
2. Apply heat to the section of pipe using an electric heating pad wrapped around the
pipe, and electric hair dryer, a portable space heater (kept away from flammable
materials), or wrapping pipes with towels soaked in hot water. Do not use a blowtorch,
kerosene or propane heater, charcoal stove, or other open flame device. A blowtorch
can make water in a frozen pipe boil and cause the pipe to explode. All open flames in
homes present a serious fire danger, as well as a severe risk of exposure to lethal
3. Apply heat until full water pressure is restored. If you are unable to locate the frozen
area, if the frozen area is not accessible, or if you can not thaw the pipe, call a licensed
4. Check all other faucets in your home to find out if you have additional frozen pipes. If
one pipe freezes, others may freeze, too.
1. Consider relocating exposed pipes to provide increased protection from freezing.
Pipes can be relocated by a professional if the home is remodeled.
2. Add insulation added to attics, basements, and crawl spaces. Insulation will maintain
higher temperatures in these areas.
3. New eco-friendly innovative technology offered by the Hot Water Lobster Instant Hot
Water Valve is easy to install (not requiring pipe cutting or electrical wiring) and a great
pipe freezing prevention aid. Installed at the plumbing fixture at the end of the “at risk
plumbing run” (pipes most likely to freeze), 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 and save energy, 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 also providing faster hot water to all
your fixtures for better water conservation
