An enlarged prostate is also known as benign prostatic hyperplasia (BPH), which is generally not associated with any prostate pain. However, an enlarged prostate can cause problems with urination.
When a homeowner turns on a faucet, the cooled water sitting in the pipes circulates to the faucet first, so the homeowner has to wait for hot water. A hot water circulation pump sends cool water in the pipes back to the water heater through a return line. A pump circulates this water through the water heater as needed to keep it hot. This continuous loop of water through the water heater ensures that hot water is always available.
1 Make sure the hot water faucets are still open and turn on the water supply. 2  This keeps air from getting trapped in the water lines. 3  Let the water flow from each faucet for one minute before turning them off. 4  Reconnect the wires, turn on the power and wait for the water to heat up.
