I have a Polaris Caretaker and the pressure reads about 2 p.s.i. while the pump is running. It does reset to 0 p.s.i. when turned off, so I don't think it's the gauge. I have a cartridge filter that reads 25 p.s.i. when running and 0 when off.
I believe the Caretaker previously would operate at 10 p.s.i. (still low from what I read), but has now diminished. I cleaned my filter cartridges earlier this year (about 3 months ago) and that resulted in the screen above the Caretaker being clogged. I got that cleaned out and everything ran great.
Two weeks ago, I noticed a leak at the union closest to the caretaker when I turned the pump on. The water would stop leaking after about 2 minutes. I took the union apart and reapplied silicon sealant to the O ring. This was not done last time it was taken apart. The screen was still clear.
After reassembling the union, the leak is gone, but the Caretaker pressure gauge still reads 2 p.s.i. This of course is too little pressure and the pop up heads are not functioning very well. I have a aerator outlet and if I divert the water return to it and then switch back to the caretaker, the pressure jumps to 10 p.s.i. for a few seconds then goes back to 2 p.s.i.
What could cause this? Is the pressure reading on the Caretaker indicating the pressure as the water enters the dome, thus the pressure being too low before going through the Caretaker internals? Or is the pressure low inside the Caretaker, maybe needing to be rebuilt? Thanks in advance for the help!
