Two Handle 8" Wide Spread Knob: Flat Cap (After 2013)

Moen produces a variety of two handle wide spread bathroom faucets. The interior components and assembly are not the same for each model. This article will explain one of the more common handle assemblies referred to as a Flat Cap Knob (after 2013). This faucet style utilizes the 1224 or 1234 cartridges.

Preparation:  The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet.


Confirm knob style: 

Gently pry the cap out of the knob. If you see a Phillips screw see article titled: Two Handle 8" Wide Spread Knob: Flat Cap (Prior to 2013).
