DE Leaking Into Pump. Please Help!

Postby sailor21 » Thu 22 Apr, 2010 15:55

I noticed my spa leaking back into the pool (spa is higher than the pool). The leak would stop right below the returns so it cannot be the spa drain.

At first I thought it would be a check valve but that line has none to be seen(I'm new pool owner).

On the pump strainer I noticed DE coming in from the pump when pump is off. The water gets cloudy when pump is off at the strainer sight glass.

Can it be the control valve (multi valve) from the filter?

When I shut the pump off and take the pump strainer cap (sight glass) out, there seems to be slight water flow if the valve to the spa returns is open.

Any suggestions?

Well, since there was no check valve on the supply line, I installed one. Then, checked the multi valve and it was broken inside, so changed it too.

Problem is still happening.

Once the pump is turned off, water can be heard coming back from the filter through the multi valve and into the pump. Dirty DE is coming out of the skimmer and main drain (spa drain is closed).

Now what?

Please help!
