Everpure/Pentair QL3 water filter leakage

[Algonquin]

I have a slow drip from my undercounter Everpure/Pentair QL3 water filter. I cannot determine if the leak is due to a defective filter housing, poor sealing at the O-rings, or from the top seam in the Pentair filter cartridge. This is an expensive filter cartridge and I hate to replace it if the housing is at fault. Has anyone else experienced this problem?

Thanks

You should be able to remove the filter and still have water pressure at the faucet. If continue to have a leak it's either in the lines or the housing is cracked. If there is no leak with the filter detached it's got to be either bad o rings in the filter or a problem with the seam.

This is external, bayonet-mounted filter. It cannot be removed and still have pressure at the faucet. However, I do have a plug that I can insert and test if the housing is leaking. Thanks

Mine dripped earlier this trip. I turned off the water hose, drained the pressure and took off the filter. Everything looked okay so I relubed the o rings and installed and no leaks-hmmm. Give it a try, worked for me.

I had the same result as G Shaw posted. Sometimes the filter does not fully seal in the lock ring, just try to remove and re install the filter. Mine came with silicon grease for the "O" ring.

Mine had a slow leak once, found out I didn't have the filter in correctly.
FYI, Everpure makes a vacationer model filter; it's about half the length of the full-timers model which is supposed to last one year, comes in a 2-pack.
The lowest pricing I've found is; believe it or not, Camping World.They do not carry the vacationer filter model though.
I use the full-timers model filter, when unused it's drained, put in a freezer bag and frozen until needed to prevent degradation from mold etc.
