I was looking at the circuit from my hot water heater and noticed something that confuses me.
My hot water heater is in the basement and the main pipe from the hot water heater has a smaller branch a couple of feet from the heater. This smaller pipe then splits. One split re-enters the main hot water pipe near the bath room in the apartment above the garage. The other split re-enters the main hot water pipe near the master bath in the house.
What is the purpose of these smaller branches that return into the main hot water line near their termination? I have never seen this before and would have thought it was not needed.
