Anyone out there own the OmniFilter U25 Whole House Water Filter? I've had
mine for over a year now, but I can't get it to seal after a recent filter
change. I've always kept the O-Ring Lubricated with faucet grease and the
Threads of the cartridge holder wrapped with Teflon Tape. I've tried
several times but I just can't get it to seal.
The filter holder is screwing into the housing correctly, not
crosss-threaded.

Any Ideas?

Thanks In Advance,
