Need a little help. When I turn off my main pump the water drains into my
wet/dry filter which is more like a sump now. However sometimes the water
level is to high and it overflows. What type of valve do i want to
install in my line to prevent water draining back down through my mag
pump? The overflow is ok because once the water drops below the overflow
it stops.
