How To Fix Bathroom Tub Valve: A Comprehensive Guide

A leaky or malfunctioning bathroom tub valve can be a major inconvenience. Not only can it waste water and drive up your utility bills, but it can also be a source of frustration and discomfort. If you're facing this issue, don't despair. Fixing a bathroom tub valve is a relatively straightforward task that can be accomplished with a few basic tools and some patience.

1. Identify the Type of Valve

The first step in repairing a bathroom tub valve is to identify the type of valve you have. There are three main types of tub valves: compression, cartridge, and disc.

Compression valves are the most common type of tub valve. They use a washer to create a seal against the valve seat. When the handle is turned, the washer is compressed against the seat, stopping the flow of water.

Cartridge valves are a newer type of tub valve that uses a replaceable cartridge to control the flow of water. When the handle is turned, the cartridge moves up or down, opening or closing the valve.

Disc valves are another newer type of tub valve that uses a pair of discs to control the flow of water. When the handle is turned, the discs move closer together or further apart, opening or closing the valve.

2. Gather the Necessary Tools

Once you've identified the type of valve you have, you'll need to gather the necessary tools to make the repair. For most repairs, you'll need the following tools:

Adjustable wrench
Phillips head screwdriver
Flat head screwdriver
Allen wrench (if necessary)
Valve stem packing (if necessary)
Replacement washer or cartridge (if necessary)

3. Turn Off the Water Supply

Before you begin any repairs, it's essential to turn off the water supply to the tub. This will prevent water from leaking out while you're working on the valve.

To turn off the water supply, locate the shut-off valves under the sink. These valves are typically located on the hot and cold water lines. Turn the valves clockwise to shut off the water.

4. Remove the Handle

Once the water supply is turned off, you can remove the handle from the valve. For compression valves, simply unscrew the handle with your hand. For cartridge valves, remove the cap on the handle and then use a Phillips head screwdriver to remove the screws that hold the handle in place. For disc valves, insert an Allen wrench into the hole on the side of the handle and turn the wrench counterclockwise to remove the handle.

5. Repair the Valve

Once the handle is removed, you can repair the valve. The type of repair will vary depending on the type of valve you have.

Compression valves: If the valve is leaking from the packing nut, tighten the nut with an adjustable wrench. If the valve is leaking from the washer, replace the washer.

Cartridge valves: Remove the cartridge by pulling it straight out of the valve body. Inspect the cartridge for damage. If the cartridge is damaged, replace it with a new one.

Disc valves: Remove the screws that hold the discs in place. Inspect the discs for damage. If the discs are damaged, replace them with new ones.

6. Reassemble the Valve

Once you've repaired the valve, reassemble it in the reverse order that you disassembled it. Tighten all of the screws and nuts securely.

7. Turn On the Water Supply

Once the valve is reassembled, turn on the water supply and check for leaks. If there are no leaks, your repair is complete.

Conclusion

Fixing a bathroom tub valve is a relatively straightforward task that can be accomplished with a few basic tools and some patience. By following the steps outlined in this guide, you can quickly and easily repair your leaky or malfunctioning tub valve and restore your bathroom to its former glory.
