Locate Water Shut-Off Valve — Shut Off Water Supply
Part of project
How to Identify and Replace Your Delta Monitor Shower Cartridge (Old vs. New) · Step 1 of 7
In this video
As a critical preparedness step, locate your home's main water shut-off valve. This is essential in an emergency, such as a burst pipe, to quickly stop the flow of water and prevent extensive water damage. The valve is often located in a basement, crawl space, utility closet, or near the water heater. Familiarize yourself with how to turn it off completely.
Goal: Identify the location of the main water shut-off valve
- If a pipe has already burst, shut off the main water supply immediately before attempting any repairs or thawing.
- Test the valve periodically (e.g., once a year) to ensure it is not seized and operates correctly. Turn it off and on a few times.

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.
