I have a fully tiled-in roman tub. The hot and cold water faucets use compression type valve stems. The washers get worn out every few months, leading to drips. I have done the following several times this past year:
- shut off main water supply to the house
- remove faucet handle/trim
- unscrew valve stem
- replace rubber washer (held in place with a brass screw)
Based on the "faucet repair kit" (from Home Depot), in which I found the compatible washer and brass screw, it seems these could be Price Pfister fittings - there are no visible names/markings anywhere.
Every time the washer wears out, we use more and more force to tighten the faucet until we are able to go through these repair steps listed above. This type of repair seems to be failing a bit more frequently now.
Is it possible to replace these failure-prone compression valve stems with a more drable kind (quarter turn etc.) without having access to the underside of the tub? Everything is unfortunately fully tiled in.
