Review on 🚿 Kohler GP800881 Genuine Pressure Balance Cartridge by Mike Littlejohn

This cartridge is a genuine Kohler replacement part and solved my little leak problem. There is no indication of this on the packaging. The main issue with this replacement cartridge is not this part, it is that the ORIGINAL cartridge started leaking in a new shower installation after less than two years! I can't bring myself to give this part a five star rating when I feel like I shouldn't have replaced the first part for years to come.
