My pump looses prime overnight. It is about 10' higher than the pool, and i notice that the basket empties out when the pump shuts down for the night. It always re-primes on it's own and has protection if it wouldn't, I just worry that this is a problem. I do not have any check valves, and the plumbing is real tight, so I would have to replace a lot of stuff to try to squeeze one in.
Is this a result of the elevation, or is there an issue? Do I need to fix it, or since the pump can re-prime in a few seconds, is it OK?
