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, -a12vman
