Temperature controlled hot water recirculating pumps are sophisticated systems. Sensors check the temperature of water going down the drain when a tap is turned on. If the temperature of the water falls below a specified level, a solenoid powered valve is activated and sends the water back to the recirculating pump.
The first step is to shut off the water on the cold side of the water heater (Image 1). Open up a hot water faucet to relieve some of the pressure in the lines. If the water heater is gas, turn the switch over to the 'Pilot' position (Image 2). If it's electric, turn the power off at the breaker.Drain about a gallon of water out of the tank (Image 3) to relieve more pressure and to lower the water level.pen up a hot water faucet to relieve some of the pressure in the lines.
