I recently purchased a Moen shower trim set and the valve to replace an existing Price-Pfister one, but my installer told me that the larger Moen valve would not fit unless I break through the 20"x20" tile on outer wall that I just had installed. He said that was the only way he could do it. I believe him so I'm opting for another route. Not wishing to purchase another PP fixture I'm wondering what other brand name would be interchangeable with the valve already in there? Or, is there another brand that would have the same size valve that could be switched out and change the brand that way?
Thanks,
OG

There is absolutely ZERO interchangebility of parts between brands. There is LIMITED interchangeability of parts between differtent models of the same brand.

Sorry to break the bad news, but this was an unfortunate planning mistake on your part.

OG, the time to have changed things behind the wall was BEFORE the wall was tiled.
as jimmy states, the only hope you have is to stay with the same brand. and even that is limited..

Nothing personal "oldgirl" but manufacturers have been doing that for years to protect their company's assets. Switching n mixing is just not done. Same applies to American Cars. You can't take wheels off a Ford and put them on a Chevy. Its designed that way.

That is one of the major reasons we ask people to PLan Ahe a d.

Whether the new valve can be installed in place of the old one using just the opening in the wall depends ENTIRELY upon how the old one was connected, and what kind of connections are on the new one. IF the old one was ALL soldered, i.e., NO threaded connections, and the new one is the same, then it is possible that there is room to do it. BUT, if either one, or both, have threaded connections then it is unlikely it could be down without removing some tile or providing other access. It could require some ingenuity. I have replaced Price Pfister valves with Moen, for example, by adding a special trim ring made for a specific version of Delta faucets.

Is the situation such that you can get to the fixture from the other side of the wall? I have sat in many closets changing out a tub/shower fixture.

Retired after 50 years of plumbing and heating.

Unfortunately, the other side of the wall is tiled, facing the room.

It sounds like once you choose a fixture, you are stuck with that brand name for the life of the fixture, maybe even life lol. I don't know what you would do if it suddenly stops working and you can't replace it even with interchangeable parts from the same mfr. I'm having to send back all the Moen stuff and try to find replacement parts from PP. Been trying to contact them for 2 days now with no success. WAited on phone yesterday for what seemed like hours until the music they played on the hold actually made me feel sick. I just want to ask them if another shower kit by them will fit the valve that's in there now before I go ahead and purchase it.

Well, I hope my mistake helps someone else.

We are not trying to rub it in to make you feel bad...but for benefit of others do try to point out the need to plan. If you could post some photos of your valve and current trim/handles we can give you a pretty good idea what will work. The older it is, the slimmer the options will be. In some cases, PP no longer makes trim at all, but an aftermarket company does. The older it is, the more likely that chrome will be your only color choice.

A shower valve is certainly expected to last the life of the shower....est. 15 to 25 years. It should not be counted on for the life of the house, although it is not uncommon to come across shower that is 50 years old. It is just getting harder and harder to find parts for those.

No, I know that you are not. But I didn't like this fixture to start with, it was given to me and I thought so that I could use my shower until I find what I actually want, I used it not knowing all this we've been discussing about changing. Because I knew the showerhead could be screwed off and changed and didn't think the handle would be different. Wasn't aware of all the valve stuff.

Sorry,I can't send an image unless it's an attachment, but it is the PP Treviso collection, R89 Series, think R89-7DCO, 'smiley' handle. Showerhead is similar to Santiago R89-7STC; and it's fairly recent. She bought it just before she gave it to me still unopened in the box. The one I was going to try to exchange it for is either the Kenzo R89-7DFC, Park Avenue R89-7FEC or Carnegie R89-7WEC. I am trying to update the bath to contemporary/minimalist style.

Left mssg with PP both on phone and email but haven't heard anything back yet. OG

what finish handle type do you seek?PP does offer some trim change overs.though I would change over this rough under most conditions to a moen positemp.Through the cover plate hole from the front side.Copper is my favorite.

There are TWO different PP valve styles. One has four bolts holding it together and the other has a single nut over the cartridge. Whichever style you have, new parts for the SAME style will normally work, possibly with an adapter, UNLESS you have an octagonal trim ring.

That series should be the four bolt style which gives you a lot of options for changing its looks.

The shower head and tub spout are independent of the valve system. You can use and brand and style for those.

Any competent plumber that has skills can work within a 4-3/4" opening created for a single handled faucet design and accomplish what you're trying to do.


I've done this countless times and it can be done with the time invested.

Try doing it on a valve with integral stops and MIP adapters in the ports. If the pipes have to be offset due to a different rough-in dimension, that will ALSO cause a space problem inside that 4 3/4" opening.

Hj a strap five inches up or down the tubing stops some.not the best.

OH DEAR GOD IN HEAVEN... you have got to be kidding me.. once a shower valve is installed it's supposed to last forever? It's not interchangeable with ANY other handle? Since when did companies start making things last forever (again)

I found this site because I have this valve Delta 600'series (???) with three small copper tubes that lead from the water pipe to the handle (??) these small copper pipes have twisted over time by over zealous handle turners... and now, after I've almost completely retiled this shower...it's begun a tiny drip.. I wasn't planning on ANY drip.. I'm not a plumber..I just wanted to retile my bathroom for gods sake.. I was quite proud that I'd managed to rmodel this bathroom for about 200 bucks ( I had the tile from years ago) and NOW it looks like it's going to cost LOTS MORE! I've done a ton of research -that's how I've found this site- I've fixed a lot of things but this one is beyond my willingness to try....

Is there any chance there is a product that will clog that pin hole leak? I tried the Fix it stick, I didn't try the tape as it's too bulky.. anything? Anything at all??

What a bummer..

Instead of waiting on hold forever, go to a plumbing supply store (not a big box store, although I've found good advice in a True Value Hardware quite often) and take pictures of whatever parts you can't bring with you, along with the parts you can. Good luck!
