Ok guys, I just upgraded my pump and filter to an Intex 2100 gph Sand filter. I followed the instructions to set it up and got it going. I noted the pressure on startup and it was about 9 (10 starts into the yellow zone). after about 30 minutes the pressure was up to 11 and the flow from the return was very slow. I would say about 1/10th of the flow compared to startup right after a backwash. So I backwashed again, rinsed, then set back to filter and all is well with pressure back to 9. but again after about 30 minutes the pressure is back up and flow is terrible. I ended up repeating this for like 2 hours last night before bed time. I didnt want to leave it running over night worried about the pressure so I set it on a timer to run for 30 minutes. This morning I went out first thing and turned it on. the flow was just ok and pressure at 11 so I went inside got ready for work and then came out and checked. pressure still at 11 but could barely feel and flow from the return. Backwash, rinse, filter and its flowing like a champ, but worried about it building pressure all day while I'm at work I turned it off.
does this sound normal for startup??? will this get better? is a pressure reading of 9 too much?? What am I missing? Help me out here. with the amount of backwashing and rinsing (replacing water) My chemistry is going to way out of whack.
