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.
Figure 3 shows how it works: Step 1: Turn on any hot water faucet in the house for 1 second and then turn it off. Step 2: The circulation pump is activated. Step 3: Cool water from the hot line is circulated back to the water heater through the cold water line.Step 4: Enjoy hot water without wasting it down the drain.igure 3 shows how it works: Step 1: Turn on any hot water faucet in the house for 1 second and then turn it off.
