Hi, I have been a member for about 1.5 years here and running into a strange situation with the pool pump. I usually have to open the filter and take out the 4-cartridge filter and hose it down every 6 months or so, when the pressure gets up to around 30 psi. Then afterwards it goes down to around 14-17 psi.
I noticed recently the pressure had gotten up to 30 psi again, so I took the filter out, cleaned it and ran the pump without the filter cartridge in it for 30-40 min to clean out anything that might have been blocking it. Pressure went down to 15 psi, then I put the filter cartridge back in, pressure was still 15 psi, everything seemed good.
That was one week ago. I checked again today, and the pressure was back up to 30 psi! This is a first. I can do the same thing again but now I am worried I will have to clean the filter every week? This can't be normal...
My pool measurements are within normal range except CYA is high, around 125. I have been waiting to drain the pool water until it got colder.
Could high CYA cause the filter to block/jam more frequently, or is this just coincidental?
Any reason why the psi would get back up to 30 so quickly? Is it ok to let it keep running at 30 PSI, or is this going to blow the pump?
Thanks again, Aaron
