Why Is My Bathtub Faucet Leaking Hot Water? What Can I Do?

When a bathtub faucet is leaking hot water, you might be tempted to just turn the valve off. However, this is not always the best solution. There are a few things that may cause your bathtub faucet to leak hot water and some ways to fix the problem without always turning off the valve. Read on to learn more about what causes a bathtub faucet to leak hot water and how you can stop it before it becomes a bigger problem.

What Causes a Bathtub Faucet to Leak Hot Water?

There are a number of reasons why a bathtub faucet may leak hot water.

There are a number of reasons why a bathtub faucet may leak hot water. The most common reason is that there is a problem with the faucet’s cartridge. A cartridge is a small, removable piece inside of the faucet that controls water flow. When water pressure gets too high, a bathtub faucet cartridge can become damaged or worn out and may leak hot water. Replacing the cartridge is often one of the easiest ways to fix hot water leaks in a bathtub faucet.

Another common reason for hot water leaks in a bathtub faucet is that there are problems with the temperature control valve, which is located under the handle of the spout. When this valve becomes worn out or damaged, it can cause hot water to leak from underneath it. This type of damage can be hard to spot, so it can be a good idea to call a plumber to inspect the valve for any problems before trying to replace it.

A third possibility for a hot water leak in a bathtub faucet is that there is some kind of damage or corrosion on the pipes. Pipes that are damaged or corroded can easily cause hot water leaks from underneath the handle of the spout. It’s important to have your pipes inspected regularly by a professional plumber and cleaned if necessary.

If you think your bathtub faucet is leaking hot water, there are several different solutions you can try before calling in a plumber. The easiest solution is to replace the temperature control valve. It’s usually very easy to replace this kind of part and only takes a few minutes. If you want to try replacing the temperature control valve on your own, you can follow these steps:

Turn off the water supply to the sink. You should be able to locate your shutoff valve under your bathroom sink or behind a cabinet in your kitchen. The valve is usually located near where the hot and cold water pipes meet up with the faucet pipes. Use a wrench or pliers to turn off the water supply, then unscrew and remove the faucet handle by loosening its set screw with a screwdriver. Remove any packing washers that are on either side of the valve stem. Use a pair of pliers to remove the packing nut and washer. You should be able to see the temperature control valve. Loosen the set screw with a screwdriver, then remove the temperature control valve by turning it counter-clockwise. Install your new temperature control valve by following these steps in reverse order.

How to Avoid a Leak in the Future

If you’re looking for a way to prevent leaks in the future, consider using a rubber washer or o-ring on the valve stem to allow more water pressure through after turning the valve off.

1) Troubleshoot with cold water flowing.

2) Replace washers or o-rings if necessary.

3) Replace cartridge and fill with water again after replacing washers/o-rings.

What causes a shower faucet to drip?

Most drip problems are caused by a valve that is worn out or improperly installed. If the faucet drips when the water is off and the handle is in the hot position, then it is likely due to a worn-out stem seat washer. The stem seat washer is located inside the valve below where the stem comes through the body of the faucet. This washer can be replaced to eliminate any dripping problems caused by this worn-out part.

How long do bathtub faucets last?

The handles are usually held on by screws, and there should be two of them on each side of the faucet.

Where is the O ring in a shower head?

How often should I change my shower head?

Cleaning your showerhead will depend on how much water is used in it daily and how much soap/shampoo you use every day.

If you’re not sure how often you need to change your shower head, make sure you take the time to clean it at least once a month.
