I'm looking at replumbing my equipment pad including replacing the pump. I'm trying to determine the system head/characteristics to determine which pump will best serve. My pool was built in 1984 and is freeform gunite with 1 skimmer and 1 drain and 4 returns in the pool side and 2 drains and 5 returns in the spa side. The suction side of my pump has 2 2 inch lines running to a 3 way valve. The 2 return lines from the pump are 1.5 inch. As best I can determine so far there is one line each for suction and return to the pool and spa.
I'm trying to figure out how the lines run underground. I think the pool suction line runs from the drain to the skimmer and then to the pump. Does that sound correct?
Would the return line be one continuous pipe with tees where the return jets are or separate lines to each jet?
Would the spa side have separate pipe runs all the way back to the pad? I think that is correct, but not sure.
My reason for the re-plumb is multiple leaks at the pad. The reason for a new pump is to get better flow and save some energy, the current is a 1 speed.
I also have a heater in the circuit which I am thinking of eliminating since I do not use it and do not intend to.
Just looking for any advice to hopefully do this right the first time, thanks.
I can post a schematic of the pool if it helps.
