## Customer Reviews

### ⭐⭐⭐⭐⭐ Buy it for the RP70538 Cartridge Valve & The RP73625 Check Valve!
*by A***K on February 27, 2021*

I needed the RP70538 Cartridge Valve - quickly, of course, due to a steady leak. All were out of stock, so I purchased this assembly via Prime, which contains both the RP70538 and the RP73625 Check Valve, which one should always purchase when replacing the RP70538. Fit my Delta single handle shower valve perfectly, for less cost than purchasing the two separately (at the time I needed them). I simply unscrewed the old assembly off, cleaned up the existing brass rough in with calcium/lime remover, installed the new assembly, and discarded the brass rough in kit (while main water valve shut off, of course). Several videos on web to help w/this.See picture of the leftover components, including the new/unneeded brass rough in valve and old RP70538 & RP73625 .

### ⭐⭐⭐⭐⭐ Tiny rubber bits pop of frozen and water does not drain.
*by T***P on January 19, 2022*

Easy to replace. But I’m my summer cottage it traps water which when it freezes pops the rubber washers. So remove from any area that will freeze over the winter like lithium batteries.

### ⭐⭐⭐⭐⭐ Good replacement.
*by R***D on April 9, 2021*

Had to buy new cover plate and handle.
