Just bought a great house with an awesome pool. Previous owner gave me a good run-down on how everything was installed and what he did to maintain. His first instruction was to get into Pool School and become pool knowledgeable (this is also my first forum post). We walked through a filter cleaning together and he told me the pump should run relatively slower once the filters have been cleaned and the pump back online, which makes sense. The filter pressure was about 8psi. He was showing me the speed in watts (about 350w) but I may have missed what the RPM were. Others I've talked too know their pump RPM speed rather than how many watts are being used.
It may have taken a cycle or two, but as is usually the case, things seemed to have changed and the pump is now running much higher than it did when we walked through it together. I also got an alert to service system soon an the pump showed that the filter was 100% blocked. I ran through a filter cleaning myself and put the unit back together, but the alert still showed on the pump. After reading the pump manual I realized this is because the pump is basing everything on pressure and the clean filter pressure was set to 10psi yet the filter pressure was operating around 20psi. Also, the pump manual said the system needed to go through a backwash cycle to clear the alert.
I'm still learning the pump control settings, but was able to switch to manual mode and the pump is now running with about 15psi on the filters. I know it's different for each pool based on piping layout, but I'm wondering what the average range of pump RPM speed, cycle times, number of turnovers in a day, filter pressure, etc,. The cartridge filters are 7years old so I'm wondering if it's time to start with a new set of cartridges before looking into other possible issues.
Appreciate anyone's support!
