So I'm cleaning my pool and my wife and I are talking about how great our new Intex Sand / Saltwater filter is.

I'm FINALLY going to get the poo out of the water tonight, and tomorrow will have crystal clear water....right?


Then, just as I am making the comment "I love how this new filter lets me vacuum this stuff up without pumping it right back in to the pool, like the cartridge filters did...."


BOOM! The sand filter pumps all of the poo back in to the pool at one time!

It was really quite funny, now that I'm not mad about it any more..... It was as if diarrhea was coming out of the jet! LMAO!



I am wondering if anyone knows what I may have done wrong.

My thought is that I vacuumed up so much 'poo' (some kind of sediment / slime from our water supply) That the pressure in the pump spiked before I was able to backwash, and it popped a release valve or something, causing it to 'backwash' back in to the pool?

Is this a possibility? It looked just like it was backwashing through the jet.


Any ideas?

Pump is less than a week old, and has been working great. I've been able to get the pool cleaner than ever with it....but now this.
