New here, so i hope i post this in the right place.
I am losing psi as the system changes zones. Starting in the deep end at 17 and ending at the shallow end with 13. I have just replace the gear parts and rubber rings but its still not working right. So the shallow end stays at 13 and never changes . I am a new pool owner for about 5 yrs, so if i missed something just let me know.
20k IG plaster chlorined (using Calcium Hypochlorite) pool
Pump : Pentair IntelliFlo, running at 2500 rps for 10hrs
Filter : Hayward SwimClear C3030 325 Sqft. I just got it a few weeks ago.
and the 5 port Caretaker 99 system for the pop-up heads, i think its Polaris
all parts are 2-3 years old and everything seems to be working, just not this psi thing.
Also i should point out that the psi in all zones were working correctly before the new filter. I had a sand filter i did not like.
