I think for now you will be fine running on low 12 hrs a day-- it's still cheaper than 6 to 8 hours on full.

I've never heard of gluing in a spider gasket. Maybe it's a brand thing or the store guys are lost. If it looks like O-ring rubber, only as a spider web, I STILL think glue is a rotten idea.

I actually think you have something stuck in the multi-valve mechanism that's keeping it from closing the chambers properly. But that's a guess.
One more thing. I thought my old cartridge was 3 yrs old. I see I became a member in 2004. That would make the filter cartridge going on its 6th yr. Mabye I should have just bought a cartridge since I got my yrs out of the original. The cartringe filter is rated for 80 gallons max and this sand filter is rated at 35. Hmm what to do. I have two fiters. . I also have the oringinal one speed matrix pump. Mabye I could sell that to recoup my costs and start over. I could sell this sand filter also and go to a 200lb unit. I am unemployed since oct, and really am on limited funds.

What to do... what to do.... I wish someone says the 1hp is fine for that sand filter. Not!!!
