How to replace washers in leaking shower faucet

I pulled the bonnet and the O ring is tweeked a bit. So I will have to make do until I return in a few days. I don't think a hardware store would carry that kind of O ring. Will replace the faucet, as we don't like the knobs and the DW would like the lever handle ones anyway.

We have Phoenix and were able to get some parts at the hardware store. I remember there was a plastic ring along with plastic teeth that held the trim piece down. 3/4" deep socket as I recall. But I forget how I got down to the hex on the washer "cartridge" other'n I broke a couple of the teeth. I replaced our kitchen sink and vanity faucets with Phoenix from Amazon. But at a visit to Home Depot, I later found they had at least some complete "cartidges" (that whole brass hex part, washer, o-rings and all) for Phoenix.

Following pic is from Amazon.


I replaced Kitchen and Vanity with the type pictured, which is a 1/4-turn "washerless" design. I parted the old ones out, keeping Knobs and Cartridges, since we still have washer-type Phoenix Shower and Outside Shower faucets.

Reluctant to try to change the washer in a faucet when I can't get a Cartridge since I've had the screw to come apart at the head or break off in the brass cartridge. If I can get the screw out I'll try to replace with stainless, new brass, or at least some compound on the treads.

The washer seats in our Phoenix faucets were plastic, molded into the base, so they weren't subject to pitting and leaks from there. If you've got a drip, should be from the washer.

If you decide you want to repair what you have and need a cartridge, let me know. I'll work on the four I have and see how many are salvageable.

take another look could be a rubber cap siting on a spring. I,ve pulled them straight out with small needle nose pliers .

Had same problem. Took into RV shop and mechanic said it will cost same whether I replaced the shower fixture or tried to repair the washer as he had to charge minimum $50 for 1/2 hour labor. Since you probably don't have the proper tools and the necessary time, pay to have it replaced whether you are on the road or at home. I upgraded to better shower valve in the process.

We're out on a trip and still have 3-5 days left. Want to stop at hardware store for quick fix. Will look into replacement when we get home.

If it were me, I would replace the cheap OEM faucet with a new one. They can be purchased on Amazon or rv store for less than $25 and likely better quality than your existing. That's what I did.
