Letting a faucet drip during extreme cold weather can prevent a pipe from bursting. A small flow of water helps prevent pipe freezing. Opening a faucet will provide relief from the excessive pressure that builds between the faucet and the ice blockage when freezing occurs. If there is no excessive water pressure, there is no burst pipe, even if the water inside the pipe were to freeze. However, a dripping faucet wastes water and wastes energy.
Instead of letting a faucet drip, simply install an innovative eco-friendly and patented technology known as the Hot Water Lobster Instant Hot Water Valve (it’s a breeze to install-no pipe cutting, soldering or electrical connections). It uses your existing water pipes and the thermal convection generated by your water heater to keep water circulating back to your water heater for reheating (not requiring a pump or any electricity). Warm circulating water will not freeze. To save hot water and save energy these hot water recirculating 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 faster hot water to your faucets and showers.
