I bought a foreclosure last summer not knowing the pool history over the winter I had my sand filter cleaned and they replaced the sand as part of the deal and they found a broken lateral. I had them fix that as well.
Yesterday, I opened my pool and had them change everything in the multi port valve, springs, gasket, handle and anything else they felt that needed replacing.
The pool was clear as can be but had a lot of worms and some organic matter at the bottom. As soon as they turned on the pump it became pretty cloudy.
I had to backwash twice yesterday and twice today. After the second backwash I noticed water coming out of the backwash pipe when the pump was running in filter mode. It is not gushing like when I backwash or rinse but a pretty steady flow.
I turned everything off and will call them in the morning but what could have happened? I always turn the pump off before adjusting the handle and turn clockwise.
