When my pool was installed a few years ago the pressure gauge on the filter read somewhere around 20. I was told to clean the filters after a rise of about 10 from the current baseline. I have down this but noticed that my pressure never really falls back to where it was the last time the filters were cleaned. It seems to rise gradually each time. I noticed that my pressure was around 32 after I cleaned the filters a couple of weeks ago. I also realized that the cartridges are about come apart so I just replaced them with new cartridges. However, there was no drop in pressure and I’m sitting with a reading of about 32. The skimmers are cleaned several times a week and are clear at the moment. The pump basket is clean etc.
So my question is this…….
Is this a problem and if so, what do I need to look at in order to resolve it? Are my skimmer lines clogged up? They seem to be working ok.
Thanks for any help.
