Pentair multi port valve 27-1141 - DE enters the pool

[wsommariva]

Hi everyone,

Fiberglass pool is 7 or 8 years old. 10,000 gal in ground. 1.5 HP pump, 36 sq ft DE Pentair filter.

I backwashed and added new DE. I noticed foam in the pool immediately. Never happened before. My Dolphin Nautilis pool cleaner picked up alot of DE. I think that most of the DE I just added entered the pool through the eyelet returns. I did some research and I need to check the manifold o ring. I will just replace it.

The grids are brand new.

I can't find any info or parts for the valve. I THINK the model is what I entered above.

Any know of problems with these types or models of valves?

Thanks

I have a Pentair Triton II. My air relief hose on the inside of my filter had lost the top filter. I reattached it, threaded the hose through the diffuser and never had sand in the pool again. I don't know ifyours works the same way, but this is one problem.
