A picture of my current plumbing setup is below. For starters - this is a new pool and I WILL be adding a check valve in location #3 near the salt system when I turn the salt feature on.
When the system is shut off - the intake valve position is 100% pool. The return valve position is 90% pool and 10% spa.
Two main questions:
1. When I turn the system off the spa (while its a champange spa it does not drain a lot) it will drop about 2 inches of water to match the level of the pool. I would like to stop that. Would adding a check valve to location 2 solve that? I'm assuming this is where the draining would be happening?
2. When I clean the filter and break the seal the pump empties and I have to add water with a hose to get the prime back. Should I add a check valve in position 1? OR - I could just rotate the manual valve that controls the pool main drain/dual skimmer flow too I guess?
Trying to go the easiest route here. If adding a check valve to position 1 would solve both my questions - I'll just do that?
