Remove the Old Valve — Remove the Old Delta Valve: Preparing for the New Installation
Part of project
Replace a Delta Shower Faucet with Monitor Series · Step 3 of 5
In this video
Using a large adjustable wrench, grip the compression nut that secures the old valve to the copper pipe coming out of the wall. Turn the wrench counter-clockwise to loosen the nut. Once loosened, you can finish unscrewing it by hand. Pull the entire old valve assembly straight off the pipe. Then, slide the old decorative escutcheon plate off the pipe as well.
Goal: Completely remove the old shutoff valve from the copper pipe
- You may need to hold the pipe steady with another pair of pliers if it moves while you are trying to loosen the nut, but be careful not to deform the soft copper.

FAQs
The project is listed as 'beginner' and 4 hours. Is it really that easy/quick for someone new to plumbing?
While installing a new Delta Monitor valve is generally straightforward, removing an old valve can vary in difficulty, especially if it's soldered or significantly corroded. Budget extra time, perhaps 6-8 hours, especially if you're a beginner or encounter unexpected issues like seized fittings or needing to cut pipes. Having all necessary tools and understanding the instructions beforehand can significantly streamline the process.
The project lists a screwdriver and a crescent wrench. Are these the only tools I'll need, or are there others that would be helpful?
While a multi-screwdriver and an adjustable wrench are essential, you'll likely need additional tools. A utility knife might be useful for cutting old caulk, while pliers (slip-joint or channel-lock) and a pipe cutter (if modifications to the existing plumbing are needed) are highly recommended. Don't forget plumber's tape or thread sealant for secure, leak-free connections.
What is the most crucial safety step I should take, besides turning off the water, to avoid damage or injury?
Absolutely confirm the water is completely off at the shower by turning on the faucet handles and letting any residual water drain before proceeding with any removal. Additionally, wear appropriate personal protective equipment like gloves and eye protection to safeguard against sharp edges, splashing water, or debris. Clear the work area of any obstructions and ensure good lighting.
The project mentions testing for leaks. What's the most common reason for leaks after installing a new shower valve, and how can I fix it?
The most common cause of leaks after installation is improperly tightened connections or not using plumber's tape/thread sealant correctly. Ensure all threaded connections are tightened firmly but not overtightened (which can strip threads), and apply plumber's tape or pipe dope to male threads before assembly. If a leak persists, carefully re-tighten the specific connection, or disassemble, reapply sealant, and reassemble.
