AvatarByLiana Farrell Faucet Queries

Your bathtub faucet is leaking hot water. It’s not a major emergency, but it’s definitely annoying. And it’s costing you money.

You’re probably wondering, why is my bathtub faucet leaking hot water? There are a few possible causes.

  • A worn-out washer. The washer is a small, rubber disk that sits between the faucet handle and the valve stem. It helps to create a seal and prevent water from leaking. Over time, the washer can wear out and become leaky.
  • A damaged valve stem. The valve stem is the part of the faucet that controls the flow of water. If the valve stem is damaged, it can cause the faucet to leak.
  • A clogged cartridge. Some faucets have a cartridge instead of a washer. The cartridge is a small, plastic or metal cylinder that contains the valve. If the cartridge becomes clogged, it can prevent the faucet from closing properly and cause it to leak.

In this article, we’ll take a closer look at each of these possible causes and discuss how to fix them. We’ll also provide some tips on how to prevent bathtub faucet leaks in the future.

Causes of a Leaking Bathtub Faucet

There are a number of different things that can cause a bathtub faucet to leak. Some of the most common causes include:

  • Loose or damaged O-rings. The O-rings in a bathtub faucet are small rubber rings that seal the faucet’s valve stems. If these O-rings become loose or damaged, they can allow water to leak out of the faucet.
  • Worn-out washers. The washers in a bathtub faucet are small metal or rubber discs that sit between the faucet’s valve stems and the faucet body. These washers help to create a seal and prevent water from leaking out of the faucet. If the washers become worn out, they can allow water to leak out.
  • Clogged aerator. The aerator on a bathtub faucet is a small screen that sits at the end of the faucet spout. The aerator helps to aerate the water and to prevent splashing. If the aerator becomes clogged with debris, it can restrict the flow of water and cause the faucet to leak.
  • Faulty cartridge. The cartridge in a bathtub faucet is a small, cylindrical device that controls the flow of water through the faucet. If the cartridge becomes faulty, it can cause the faucet to leak.
  • Broken valve stem. The valve stem in a bathtub faucet is a small rod that controls the flow of water through the faucet. If the valve stem becomes broken, it can cause the faucet to leak.
  • Damaged faucet body. The faucet body is the main part of the bathtub faucet. If the faucet body becomes damaged, it can cause the faucet to leak.

How to Identify the Cause of the Leak

The first step in fixing a leaking bathtub faucet is to identify the cause of the leak. There are a few different ways to do this:

  • Visual inspection. A visual inspection is the easiest way to identify the cause of a leaking bathtub faucet. Simply look at the faucet and see if you can see any obvious signs of damage or wear and tear.
  • Turn off the water supply and listen for the leak. Turning off the water supply to the faucet will help you to narrow down the source of the leak. If the leak stops when you turn off the water supply, you know that the leak is coming from inside the faucet. If the leak continues even when you turn off the water supply, you know that the leak is coming from outside the faucet.
  • Flush the faucet. Flushing the faucet will help to clear any debris that may be clogging the aerator or the faucet body. If the leak stops after you flush the faucet, you know that the leak was caused by a clogged aerator or faucet body.
  • Use a flashlight to look inside the faucet. Using a flashlight to look inside the faucet can help you to identify any damage or wear and tear on the valve stems or the cartridge. If you see any damage or wear and tear, you know that the leak is coming from inside the faucet.

How to Fix a Leaking Bathtub Faucet

Once you have identified the cause of the leak, you can fix it. Here are the steps on how to fix a leaking bathtub faucet:

1. Turn off the water supply to the faucet. This will prevent further water damage.
2. Remove the faucet handle. This will give you access to the faucet body.
3. Remove the old faucet cartridge. The cartridge is a small, cylindrical device that controls the flow of water through the faucet. It is usually located in the center of the faucet body.
4. Install the new faucet cartridge. Make sure that the new cartridge is the same size and type as the old cartridge.
5. Replace the faucet handle.
6. Turn on the water supply to the faucet.

Preventative Measures

There are a few things you can do to help prevent your bathtub faucet from leaking in the future:
