Hot water heater install code question
Looking at my propane hot water heater, it has a cold water incoming line coming down from the ceiling. Separately there is another cold water line coming down less than two feet away which connects to a safety valve off the hot water line. Is there any reason there two line can not be combined coming down from the ceiling and then split at the valve location? It seems that this would accomplish the same purpose with less pipe. I would like to make changes here for other reasons, but one pipe is approximately 10 feet long and comes down in the room unsupported for the full length so I would like to replace both with a single pipe running down a wall with a Tee at one point to connect to the safety valve with the other branch following the wall to near the floor before coming out to meet the water heater cold input connector..
