Hopefully this is the correct forum for this topic, wasn't really sure since it's related to an AGP. I've used Intex pools for the past 4 or 5 years, but finally decided to go all out with the 18' Ultra frame and the sand filter pump from Intex (so a complete newb in that way). Anyway, the problem I am having is that my pressure readings on the gauge when the pump is filtering usually stays at the line separating green and yellow on the gauge - I can get the exact psi reading if needed.
The pump seems to have a lot of pressure/flow out into the pool, however, after a couple hours of running the pressure or flow coming out into the pool drops quiet a bit. I backwash, and it's okay for yet another 2-3 hours. The pressure reading never appears to fluctuate much if at all. It does drop to zero when testing, but jumps back to that level when I switch to filtering.
Few other things.. It's only been up about a month and is still fairly clean, but since we can't run the pump for longer periods of time it is a little milky now. I used the sand that WalMart sells, which is where I bought the pump. I tried searching here and Google, but couldn't find any answers or overlooked it.
Thanks very much!
