Review on 🔧 Pfister 9740350 Genesis 26 Series Cartridge Sub Assembly: Enhancing Performance and Durability by Orlando Mohr

I have an old Price Pfister vanity faucet that uses a 974-505 cartridge that is no longer made. Price Pfister says it's a 974-035 replacement cartridge. This cartridge fits perfectly and works. However, there are two things: (1) Be careful when tightening the plastic nut that goes right over the cartridge. You must tighten it to prevent the cartridge from leaking. However, since this nut is plastic, you must be careful not to damage the threads on the outside of the nut. These external threads are needed to put the metal ring on before the handle is reassembled. (2) Depending on your faucet, your hot/cold may be reversed. Usually cold on the right and hot on the left (at least in the US). The cartridge only goes one way and once installed I now have hot on the right and cold on the left. Annoying, but at least it works.
