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 When your hot water heater turns on the water expands as it heats. 2  That creates pressure within the water heater tank. 3  In non technical terms, if you have what is called an âopenâ system, this extra volume of water can flow back into the main to the city if it needs to.ttach a hose to the drain valve at the bottom of the tank. Run the other end of the hose to lower place where you can drain rusty hot water without causing damage. Open a hot water faucet in the house to let air into the tank.
