3 Handle Shower Faucet Won’t Turn Off? : How To Fix It

A 3 handle shower faucet that won’t turn off can be a frustrating problem to deal with, but it’s not an issue that you have to live with. In fact, fixing a shower faucet that won’t turn off is often a relatively simple process that can be completed with just a few basic tools and some know-how.

In this step-by-step guide, we’ll walk you through the process of fixing your 3 handle shower faucet and getting your shower back under control.

Understanding Your 3 Handle Shower Faucet

Before you can start fixing your shower faucet, it’s important to understand how it works. A 3 handle shower faucet has hot and cold water handles, as well as a diverter handle that controls the flow of water to the showerhead or tub spout.

When the handles are turned, they open or close valves that control the flow of water. If any of these valves become damaged or worn, they can cause problems with your faucet.

Identifying the Problem

The first step in fixing your shower faucet is to identify the problem. If your faucet won’t turn off, it’s likely that there’s a problem with the valve that controls the flow of water. One common issue is a worn or damaged washer in the valve. Another issue could be a buildup of mineral deposits in the valve that prevents it from closing completely.

Tools and Materials You’ll Need

Before you start fixing your faucet, you’ll need a few tools and materials. These include:

• Adjustable wrench
• Screwdriver
• Replacement washers
• Penetrating oil
• Vinegar

Step 1: Turn off the Water Supply

The first step in fixing a 3 handle shower faucet that won’t turn off is to turn off the water supply to the shower. This will prevent any further water from flowing through the showerhead and make it easier to work on the faucet. Locate the shut-off valve for the shower and turn it clockwise until it’s fully closed.

Step 2: Remove the Faucet Handle

Once you’ve turned off the water supply, you can start to disassemble the faucet. Start by removing the handle on the faucet that is giving you trouble. This is usually held in place by a set screw that can be removed with an Allen wrench or screwdriver. Once the screw is removed, you should be able to pull the handle straight off.

Step 3: Inspect the Valve

With the handle removed, you should be able to see the valve stem that controls the flow of water through the faucet. Inspect the stem for any signs of damage, such as cracks or corrosion. If the stem is damaged, you’ll need to replace it before you can proceed.

Step 4: Check the Washer

If the valve stem looks okay, the problem may be with the washer. This is a small rubber or plastic disc that sits at the base of the stem and prevents water from flowing through the faucet when the handle is turned off.

Over time, washers can wear out or become damaged, causing them to fail. To check the washer, remove it from the stem and inspect it for any signs of wear or damage.

Step 5: Replace the Washer

If the washer is damaged or worn, you’ll need to replace it. To do this, take the old washer with you to a hardware store and purchase a new one that matches the size and shape of the old one. Once you have the new washer, slide it onto the stem and reassemble the faucet.

Step 6: Reassemble the Faucet

With the new washer in place, you can reassemble the faucet. Slide the handle back onto the stem and tighten the set screw with an Allen wrench or screwdriver. Turn the water supply back on and test the faucet to make sure it’s working properly.

Conclusion

In conclusion, fixing a 3 handle shower faucet that won’t turn off is often a simple process that can be completed with just a few basic tools and some know-how. By following the steps outlined in this guide, you should be able to diagnose and fix the problem with your shower faucet in no time, and avoid unnecessary water wastage and increased utility bills.
