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

The hard part was getting the handle off - finding the right size and fitting the Allen key was the hardest part. My faucet came with a serrated top vinyl nut. A channel key was required to remove it. Replaced with a 9417110 Pfister brass lock nut well worth the investment. The only problem concerns the construction of the crane. The cartridge assembly has oval o-rings that press against the flat surface of the hot/cold/pressure fittings. It looks like you overtightened the locknut and compressed the o-rings too much. Conclusion: No more dripping faucet with a new cartridge and lock nut.
