Disassemble Faucet Handle and Escutcheon Plate — Remove Handle and Trim

How to Identify and Replace Your Delta Monitor Shower Cartridge (Old vs. New) · Step 2 of 7
In this video
Begin by disassembling the faucet handle. Use a small, pointed tool like a dental pick or small hex key to carefully pry off the decorative cap on the front of the handle. Then, insert the correct size Allen wrench into the set screw located under the cap and turn it counter-clockwise to loosen it. Once loose, pull the handle straight off the valve stem. Next, use a Phillips head screwdriver to remove the two screws holding the large, circular escutcheon plate to the wall. Gently pull the plate off to expose the valve body.
Goal: Expose the shower valve cartridge
- Place all small parts like screws and caps in a container or the sink drain (with the stopper closed) to avoid losing them.

FAQs
How do I confirm if I need the older gray RP19804 or the newer white RP46074 Delta cartridge before I start disassembly?
While some Delta handle styles can offer clues, the most reliable method is to remove the handle and trim plate to visually inspect your existing cartridge. Note its color (gray or white) and any distinguishing markings or numbers to ensure you purchase the correct replacement part.
The project lists several tools; which are absolutely essential for a successful cartridge replacement, and can I use basic alternatives?
You'll primarily need slip-joint pliers or Channel Locks for gripping the bonnet nut and a Phillips head or flat head screwdriver for the handle and trim screws. While specialized tools are listed, basic versions of these are often sufficient. Ensure your chosen pliers can provide a secure grip without damaging plastic components.
What should I do if I can't locate my main water shut-off valve, or if the water doesn't completely stop flowing after I turn it off?
First, check for an individual shut-off valve to your bathroom or shower, often found behind an access panel. If no such valve exists and the main shut-off is inaccessible or faulty, it's best to contact a professional plumber to avoid water damage and ensure a complete water stoppage before proceeding.
I've replaced the cartridge and reassembled everything, but the shower still drips, leaks, or has reduced flow. What could be the issue?
Double-check that the new cartridge is fully seated and properly oriented; the 'H' and 'C' markings usually align with the hot and cold lines. Ensure the bonnet nut is tightened securely, but not overtightened, and verify that all O-rings are in place and adequately lubricated with plumber's grease.
