I have a Black Diamond 90sq ft cartridge filter from American pool sales here's the prob:::
To clean my cartridge:
I turned pump OFF
Closed off the intakes from the pool
Released to air valve on top of filter
Unscrewed top ring to get at the cartridge
Removed cartridge and cleaned ...no prob
Now water level is about 2inches from top of opened filter canister.
I put the cleaned filter back in ,Screwed the top cap back on til it lock clicked
With the top back on and water valves open, i unscrew the little air valve til water comes out to prime.
BUT when i prime the filter and fill the whole canister i get drips around the locking ring that keeps the top on.
When i keep the water level just under the very top of the cartridge no leaks......
Should the water level in the filter be just under the top of the cartridge?? or should the whole filter canister be filled ??
Pressure is at 10psi , which its been all summer
