Key Takeaways
- Understanding the type of faucet you have is crucial in fixing a leaky bathtub faucet.
- Gathering the necessary tools and materials is important before beginning the repair process.
- Shutting off the water supply and disassembling the faucet are key steps in repairing a leaky bathtub faucet.
Understanding the Problem
A leaky bathtub faucet is a common problem that can cause a lot of frustration and increase your water bill. If you notice a constant dripping sound or see water pooling around your faucet, you likely have a leak.
The most common cause of a leaky bathtub faucet is a worn-out washer. The washer is a small rubber or plastic piece that sits inside the faucet and helps create a seal to prevent water from flowing when the faucet is turned off. Over time, the washer can become worn or damaged, causing water to leak through the faucet even when it’s turned off.
Another possible cause of a leaky bathtub faucet is a corroded valve seat. The valve seat is the part of the faucet that connects the spout and the faucet body. If the valve seat becomes corroded or damaged, it can cause water to leak through the faucet.
It’s important to fix a leaky bathtub faucet as soon as possible to prevent further damage and reduce your water bill. Even a small leak can waste a significant amount of water over time. For example, a faucet that drips once per second can waste over 2,000 gallons of water per year.
In the next section, we’ll go over some steps you can take to fix a leaky bathtub faucet and stop the drip for good.
Identifying the Faucet Type
If you want to fix a leaky bathtub faucet, the first step is to identify the type of faucet you have. There are several types of bathtub faucets, and each one has its own method of repair. Here are some common types of bathtub faucets:
Compression Faucets
Compression faucets are the most common type of bathtub faucet. They have separate hot and cold water handles, and when you turn the handle, it compresses a washer against a valve seat to stop the flow of water. If your faucet drips when it is turned off, it is likely a compression faucet.
Ball Faucets
Ball faucets have a single handle that controls both hot and cold water. They have a ball-shaped valve that rotates inside the faucet body to control the flow of water. If your faucet leaks from the handle, it is likely a ball faucet.
Cartridge Faucets
Cartridge faucets also have a single handle that controls both hot and cold water. They use a cartridge to control the flow of water. If your faucet drips from the spout, it is likely a cartridge faucet.
Ceramic Disc Faucets
Ceramic disc faucets have a single handle that controls both hot and cold water. They use two ceramic discs to control the flow of water. If your faucet is leaking, it is likely a ceramic disc faucet.
To identify the type of faucet you have, look for the manufacturer’s name or model number on the faucet. If you can’t find this information, take a picture of the faucet and bring it to a hardware store or plumbing supply store. They should be able to help you identify the type of faucet you have and provide you with the necessary parts to fix it.
