Understanding Angle Stops

Angle stops are small shut-off valves found under sinks and toilets, connecting the main water supply line to your faucets, toilets and other fixtures. These valves allow you to control the water flow to a specific fixture without shutting off the entire home’s water supply. Angle stops can wear out over time, leading to leaks or, in worst-case scenarios, failure to turn off the water supply when needed.

Replacing Angle Stops

Before you begin, make sure you have the necessary tools and materials, including a new angle stop, an adjustable wrench, a pipe cutter, Teflon tape and a bucket to catch any water spillage.

Step 1: Turn off the main water supply

Before working on any plumbing project, it’s essential to shut off your home’s main water supply. Locate your home’s main water shut-off valve, typically found in your basement or crawl space near your water meter. Turn the valve clockwise to shut off the water supply.

Step 2: Remove the old angle stop

Place a bucket under the old angle stop to catch any residual water. Using an adjustable wrench, disconnect the supply line from the angle stop. Next, use the pipe cutter to cut the pipe just above the old angle stop, taking care not to damage the pipe.

Step 3: Install the new angle stop

Wrap Teflon tape around the threads of the new angle stop, ensuring you wrap it in the same direction as the threads to create a tight seal. Position the new angle stop onto the pipe and use the adjustable wrench to tighten it securely. Connect the supply line to the angle stop, taking care not to overtighten.

Step 4: Turn the water supply back on

Once you’ve replaced the angle stop, turn the main water supply back on by turning the valve counterclockwise. Check for any leaks around the new angle stop and supply line connection. If there are no leaks, you’ve successfully replaced your angle stop.
