I just set up my intext sand filter 1 day ago. When I first turned it on it ran fine and then about 2 hours later the water gs,oing back into the pool starting slowing down to a stop. I backed washed a couple times and it work for about 2 hours and then did the same thing. I've checked all the lines, looked for any leeks and didn't see any. I was wondering if it's just something that happens. I tried it on a continuous cycle and it still happed, then changed it to a 4 hour cycle and it still happened. Any suggestions? I'm at my wits end. I'm planning on calling the manufacturer tomorrow. Think maybe a pool place might be able to help figure it out?Our fill water (city) also had a high iron content. The sand filter cleared it up. Before we got the new pump/sand filter we were using the small cartridge filter and it was pretty much worthless.
