Hi! I've been reading and searching the forum, and haven't seemed to find this exact problem, so I figured I'd post my question.
I have a 16x16 ez-set pool that came with the little lame cartridge filter. I just upgraded to the 2650 Intex sand filter, and it seems to keep clogging in filter mode.
Here's what I mean... If I put it in recirculate mode, it'll almost blow water out of the pool, if I backwash, then run in filter mode, it's nice and strong, however, about 3 hours later, there is barely any pressure coming out of the pool side nozzle, and the PSI seems to go up to around 20. I backwash again, and it's good for a few more hours.
I did not know about rinsing, so I did blow some sandy water back into the pool at one point.
why would it be binding up? could I have blown sand into the hoses?
when I backwash, should the water be sandy?
The problem is definitely not the pump, it seems to be in the filter..
filter and sand are 2 days old.
