Is there any nice way of identifying which model of Peerless Bathroom Faucet I have?

Question

I have a 2 handle bathroom faucet which says Peerless on the underside. It came with the house when I bought it and I don't have the packaging or manual for it. I am trying to identify the correct stem unit assembly for it to stop a small drip and I know how you have to get the right part for the right faucet or it will not fit. I tried the website for Peerless and the 3 candidates I came up with for replacement part are (although none look like the replacement part):

1. RP70201 - Got a pack, doesn't fit
2. RP71444 - Doesn't match the look of the old part, but it is a replacement for many models. Could try that next
3. RP41701 - Doesn't match the look of the old part, but readily available

So is there anywhere/any way I can tell for sure. I could post a picture of my faucet if helpful. I could even uninstall my old cartridge and post a picture of that if it helps.

Answer 1

Since the cartridge is out, take it to a plumbing supply house not your local big-box home improvement center.

Odds are very good that they'll either

• know off the top of their heads,
• be able to find a part number that you're missing,
• or just simply walk to the back and open 12 boxes looking for one that matches and sell you that one.

One additional tip: Call ahead. Some places will only sell wholesale, i.e. to commercial plumbers. Others will sell retail, i.e. to you.

Answer 2

Although @FreeMan gives sound advice, I really don't have anybody to go to, especially in the current half-closed world. So I bought RP41701, and although the base of the cartridge looked slightly different than the old part, it actually did fit and lo and behold I have hot water without any drip. Problem solved.

Answer 3

On the Peerless customer support page, click Contact Us to get to a web form to request help.

There you can upload a photo of the faucet so they can identify the faucet model and its parts.
