I just opened my pool for its 4th season (23K gal gunite). I have a
PacFab Clean and Clear Plus Cartridge filter system.
The water was pretty gunked up at opening. When I started the pump up
it was reading 10psi (which is a very normal reading). A few hours
later it was up to almost 20psi (again normal because the filters got
gummed up). I took the filters out and cleaned them. But now, the
pressure reads about 1-2 psi.
Something seems very wrong. The pool is filled to the top and there

Any idea what might be going on? Perhaps the gauge suddenly went bad?
The needle does "jump" up and down a few psi when I first start the
system - does this jumpiness (not a smooth motion) indicate a bad
Thanx in advance.
