When I change the pump basket, directions say to relieve the pressure. Well soon as the pump is off, the pressure gauge does to zero so not sure what else this means. But to be on the safe side, I open the pressure valve and keep it open. Would the lid of the pump be under pressure otherwise? I just want to be safe.
But then what happens is that it seems all the water from the filter goes back out, and washes down the suction side and even washes back out into the pool. It takes the leaves with it that were in the pump basket I was trying to clean in the first place.
So then I'm left with a basket that I can only fill with water until the suction inlet (the rest runs down and out suction side), and starting it up it takes what feels like a long time to prime again.
I dont want to ruin anything by making in prime in this fashion if its not supposed to do this every week, and also it doesnt seem right for everything to wash back out suction side again defeating the whole purpose.
The pump sits higher than the pool which probably creates this problem, but I also have no valves on the equipment other than what I think is the backwash valve just outside of the filter.
