Review on American Standard Reliant+ Bath/Shower Pressure Balance Cartridge 051091-0070A - Black by Nick Henning

I was very annoyed at the lack of photos! 077171-0070A; and that is 051091-0700A. Model 077171 was noticeably different - definitely not what I was looking for. , up to the moment you try to attach the mounting plate! Definitely not a game. FYI, the cartridge appears to be the same for the 051091 and 952100. The 47mm cartridge 023529-0700A fits very well. Please note these photos are of my old broken block. The leak was due to a small crack at the top of the larger hole. In one of the pictures I took showing the back of the unit, you only see one o-ring. Actually there are two. Be sure to remove the old ones from the valve before installing the new block! Oh! Very important! There are NO mounting plates or screws included, so don't throw away the old one! Yes, I see that the description says "washer and screws included" but that's not true. The mounting plate is the piece of metal that holds the balance block in place and the cartridge also bolts to the plate. The order of assembly is as follows: valve > balancing assembly > mounting plate > cartridge > handle. My plate is some kind of metal (steel? I don't know) and I'm willing to bet it will never let me down.
