Standard Moen Valve/trim kit to Posi-Temp Moen valve/trim kit

[Samfran]

I just bought a house built in 1990. All three bathrooms have Moen standard trim kits (escutcheon screws at 5:00 and 7:00). All are leaking at one point or another (shower head, spout, etc).

As a rookie, I bought some Moen combo kits that include tub spout, shower head, posi-temp cartridge/escutcheon. Can I replace standard with posi-temp without having to take the wall apart? I have attached pictures of the existing escutcheons.

The three Moen kits I purchased are the Ashville 82877 - tub/shower, the Banbury 82910 - tub/shower and the Adler 82604 - shower only. All have the posi-temp valve and trim kit.

Do I need to return these and find standard kits? Any help would be appreciated. I have a plumber to install them but don't know that I have the correct kits. I don't want them to have to charge for two service calls as it is already money I hadn't planned on spending right now.

Thanks!!
Sam

Sam,
The Posi-Temp cartridge won't work, and the Posi-Temp trims won't work on those. Return what you have bought.
Moentrol trims will work and they also take the same cartridge.
1200 or 1225
You will need the Moen 145058 conversion piece that allows you to use the Moentrol trim with the old chateau body.

Moen 145058

Or you can pick up the old style Chateau trims too. Those come with the crystal knob or with a lever.

The old style before pressure balancing.

Thanks so much for replying! Had a feeling I would have to return them.

Works with the old Moen valves.
