Bathroom faucet supply lines need to be replaced every 10 years to ensure that they’re doing their job well. However, replacing supply lines can be quite tricky. Unless you have enough experience working with plumbing installations and fixtures, it’s best to leave the job to a professional plumber.
If you’re confident that you can do a great DIY job, check out some tips to keep in mind if you’re wondering how to replace bathroom faucet supply lines.
Shut off the Water
The first step on how to replace bathroom faucet supply lines is to make sure that the water valves connected to the faucet are properly shut off. Most of the time, these valves are located under the sink. If you can’t find them, you can just turn off your main valve. Next, turn on your faucet to get rid of the remaining water pressure.
It’s also best to have a drip pan ready in case the valves leak. Don’t worry if this happens. Leaking is reasonable because the valves usually don’t get shut off unless repairs are necessary.
Remove the Old Supply Line
Before you can install the new line, you must first remove the old one. Check out the following steps for how to replace faucet supply line:
- Find or purchase an open-end wrench. You’ll use this to loosen and tighten the nuts on your supply line. If you have a plastic P-trap (the curved drainpipe under the sink), you can try loosening the nuts by hand or with adjustable pliers.
- If you have an older home, you’ll most likely have copper lines. Check for mold first because this type of material is susceptible to corrosion and mold growth. Clean off the mold with some bleach.
- Use the wrench to loosen the nuts securing the line. Remove the existing supply line.
Install the New Supply Line
After you’ve successfully removed the old supply line, it’s time to install the new one. Below are the steps you need to follow for how to replace bathroom faucet supply lines:
- Attach the new line to the sink in the same way as the old one. Make sure that the opening is approximately an inch above the drain on your wall. Doing this will help you avoid overflows. If it’s too long, use a hacksaw to cut it short.
- Unless you have a compression connection, wrapping some plumbing tape around the connection threads is highly recommended.
- Turn on the water to check if there are any leaks. If this is the case, tighten the nuts again to secure the line.
