I opened my pool today and started my routine in balancing the water with BBB. I've been an avid follower for the past 4 years and have great results.
Anyway, I notice my PSI guage is reading 21 (after cleaning/backwashing). Over the past few years, my pressure's always been 18. THis is getting to me. The water is moving through the pump nicely - no air pockets seen. No leaking air/foaming through the returns that I can tell. The returns seem as strong as I remember - so I'm not detecting anything there. The only thing that may be slightly off is my skimmer. Doesn't seem to be pulling things in like it used to - but this could be my imagination at work trying to find something!
I guess I could just accept the 21, but just wondering if anyone out there could suggest any thing to check given the "clockwork" 18 I'm used to seeing year after year.
Running a Hayward Superpump and Hayward Sand Filter in an IG FG 10K gal pool. Both originals - 5 years old. No maintanance on either ever done. Also have a Hayward chlorinator attached that I haven't used in years. The plugs on the chloronator and pump are tight.
