RP70538/73625 Replacement for Peerless Tub and Shower Pressure Balance Cartridge and Valve Assembly (Cartridge and Check Valve Assembly)

I used this to replace a freeze-damaged valve in our lake house. It fit right in, works great. I used some silicone O-ring grease on the silicone bits on the outside before I put it in; not sure if that's necessary.The installation sheet tells you to refer to your original Delta/Peerless installation manual to setup adjustment. I didn't have mine anymore. If that's you, too, pulling up the O-ring on the brass shaft lets you lift the adjustment arm (it's on splines) so you can set it to match the one you're taking out. Hope that helps someone. Took me a minute to figure it out...

This one is better quality than some of the other brands and it comes with the additional piece that is needed at no additional cost . ***take note- most only come with just cartridge

Easy to install, just watch youtub video :)

fit and worked perfectly

This unit fixed my leak quickly and was easy to install. Old unit had no visible damage.

Fit like the original and solved my issue.

We bought a new delta shower and after installation plumber found faulty cartridge so after trying to go through delta for replacement parts for new shower for three days with very little success….. ordered replacement parts … received and now works just fine….. except turned out to be very expensive install. Will not buy delta again.

Make sure you fine tune by pulling the little o ring off and makign it hottet than it's current setting
