I bought a new pump and filter for my pool and was planning on cleaning up my existing plumbing while everything is torn apart. This is for a 24k gallon indoor pool.
- My biggest question is around the fact I have a heat pump and a gas furnace for the pool, can they be in series where the heat pump may maintain temperature and the heater will only kick in if the heat pump is bypassed of can't get the temperature up or are they required to be in parallel with a check value on the outlet side of the heat pump? I plan on adding a few valves for the heat pump so it can be bypassed and drained for the winter.
- All of the existing plumbing is 1.5 inch PVC will I have any issues with upgrading everything at my pump station to 2 inch PVC?
- Should I install check valves between the skimmer/drains and the pump as well as before the return?
- Are there any problems with installing more unions so they system can be taken apart for service? (you can see from the attached photo that space is at a premium.)
You can't see it in the attached photo but the heat pump is just outside the exterior wall. Any other suggestions would be greatly appreciated.
