Mighty Favog Posted December 15, 2020 Share Posted December 15, 2020 Hey y'all... We've had the same shower valves for about 15-years with no problem. The hot valve (no diverter) started leaking through the shower head about 8- months ago. Since then I've replaced that valve 3-times because the same one starts leaking again. I've replaced it with the same brand/model from Home Depot and Lowes (Danco). But today I went to a plumbing supply company (Winelson) and got one where the packaging looks bit more industrial thinking changing brands might help. Something I've noticed when I go to swap out a valve is that the small bit of "lubricant"(?) is gone between the two ceramic discs that contact each other that lets the water flow or not. One other thing, my wife likes to make her instant coffee strait from the faucet. Thus she has the water heater set reeeeeaaaallly high. Could this be a factor in the lubricant getting washed out of the valve? Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted December 15, 2020 Share Posted December 15, 2020 It looks like the o-ring is rolled on that one. Have you been replacing the whole assembly? What does the mating surface of the housing look like on the bottom most part? Quote Link to comment Share on other sites More sharing options...

For a Price Pfister. looks like the O-RING at the end is compressed or worn , you can replace it with a new one -are there any rubber discs on the end of this part ? , if there are , you can change the discs using a flat screwdriver ---avoid over tightening the valve when you screw it in , snug is good enough , put a bit of oil on the theads before screwing it in - -changing brands /great idea-------could be there is defect in this part --- Quote Link to comment Share on other sites More sharing options...

Skelt Posted December 15, 2020 Share Posted December 15, 2020 Do you know someone with a small lathe? Polish the valve seat if pitted and not too deep. Quote Link to comment Share on other sites More sharing options...
