Gov. Jerry Brown recently issued an edict requiring that Californians reduce their nonagricultural water consumption by 25 percent. There is a very simple way to help get us to this figure: a hotwater recirculating pump.
This simple, modestly priced device attaches to the hot water line coming out of your hot-water storage tank or hot-water source. Under the sink at the farthest point away from the tank, a flexible return line connects the hot water and cold water lines. This provides the recirculating loop. Hot water is delivered to every tap in seconds, not minutes. Cold water is warmer than normal, but not hot. Most pumps have a clock that can be programmed to operate at different times of the day, say in the morning and evening when people are taking showers or washing dishes. This also saves electricity. Instead of watching our precious water run down your drain waiting for it to get hot, it’s hot almost immediately. The devices work and save water. Recirculating pumps can be purchased at Home Depot, Lowe’s or other home supply stores and are installed by a plumber. I just had one installed for around $200, parts and labor.
