Slide the trim sleeve back over the cartridge and onto the valve body. Re-attach the faucet handle, ensuring it is properly aligned, and tighten the set screw with the Allen wrench. Once everything is reassembled, slowly turn the water supply back on. Test the faucet by turning it on and off, checking for any drips from the showerhead or around the handle. The repair is complete when the faucet operates correctly with no leaks.
Goal: Complete the repair and verify it's successful
- Turn the water back on slowly to check for leaks at the connections before turning it on fully. This can prevent a large spray if something isn't seated correctly.
- These cartridges often have a temperature limit stop that can be adjusted. You can set this before putting the handle back on if you want to change the maximum hot water temperature.

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.
