I am having an issue with my pump not priming from the pool, but it primes just fine from the spa. Let me give you the full story.
Back in late February the pump kicked on overnight due to it's freeze protection activating. When I awake the next morning, the pump motor had burned itself out.
Due to a combination of lack of time and money it had to wait until last weekend to get repaired. Now I have a new Motor on my pump, but it will not prime from the pool. If I set my suction to the SPA, the pump primes fine, then I switch the valve to the pool and it continues pumping fine. Turn the pump off, and restart it and it pumps just fine from the pool. But if the water drains back out of the filter/pump for any reason (like cleaning the filter, or the strainer basket in the pump) then I have to swotch back to the SPA to prime the pump, then switch back to the pool.
My concern is that if something happens again and the pump loses prime I'll burn up another motor.
I have begun shocking the pool, but can't quite see the bottom yet, is there any test I can do to verify it is actually pulling water through the main drain (i.e. is there a way to block the skimmer basket as I can see it is sucking in water fine)?
