Happy Summer, ya'll!
Having a little bit of an issue with constant pressure buildup in my Hayward sand filter. Here's what's happening:
- Water chemistry is good. pH 7.4, FC 5, CC 0, CYA 40, CH 210, TA 85. 25,000 gallon in ground pool. Hayward 1 HP pump.
Water is crystal clear and the water level is where it needs to be. The pool was very dirty when I first opened, but I treated it in a timely and effective manor by SLAMing it.
Also, I did not vacuum any debris with a vacuum attached to my system. The vacuuming was done with my robot, and a leaf vacuum that attached to my garden hose, so I'm thinking that there isn't a clog in my plumbing (but, who knows.)
-I initially thought my filter needed to be back washed since the pressure was getting past 20 quickly. I back washed about 4 times before realizing, this wasn't the solution. The pressure would drop down to 10 for a few hours after back washing, but then it would go right back up to 20-24.
-When I run the pool in recirculate mode, the pressure stays at a constant 10. I've been lurking this forum for a while, and I've seen people say that the pressure should be ZERO in recirculate mode. Is this true? I replaced the pressure gauge literally last week... so I'm assuming it's working well. The gauge goes to 0 when the system is off. So I'm confused as to why my pressure is 10 in recirculate mode.
-The return jets seem to be running well even though the pressure is reading high. They aren't as strong as they are immediately after back washing with a pressure of 10 PSI, but they're still moving the water at a decent rate.
A few other things: I had to re-plumb a few fittings before getting my pump back on when opening the pool. At first, there were slight water leaks in the fittings so I cut them and re-plumbed them again and the leaks 100% stopped. I also had a bad drain cap on the bottom of my filter for a few days that was leaking, I had since replaced that and the water stopped leaking there as well.
I believe the pressure buildup in my system is due to air getting in somehow. Maybe it's residual air from the initial bad plumbing or the bad drain cap, but I've since back washed a few times (which should purge out that air).
Also, my Sand Filter is making a weird crackling noise the top of the multi port valve. This noise DOES NOT happen in recirculate mode, just filter mode.
Does anyone know what could be going on? I'm gonna check my pump gasket O-ring, union O-rings and pump drain plugs later today to make sure they're all good. Other than that, I really don't know how air could be getting it. My filter does not have an air purge valve, so I don't even really know how to temporarily relieve the air without back washing and I really do not want to backwash again.
Could the high PSI be happening from something else? Any help would be greatly appreciated.
