What do you think of those cartridge faucets I have one I changed twice and it still drips, did the non hardening silicone lube on it looked at it for burs nothing seems to take care of it.
Usually a new cartridge works and is the only way to fix them. Unless they are the type with a kit. Some you could change springs and orings. The ones I need to do is the big stems with washer and seat.
My kitchen faucet is a cartridge. Started leaking when was only a few months old and found it was the outer ring was not holding it tight. Had nothing to do with the cartridge.
