Some might wonder why they need a plumber to change their bathroom faucet. This blog post will answer this question. The act of changing a bathroom faucet requires a fair deal of precision. Here is how to replace your bathroom faucet.
Of course, replacing a faucet doesn’t require an expert in plumbing. However, one wrong move and you’ll risk breaking it altogether. If you can’t do this yourself, contact us, and we’ll solve your problem.
1. Disconnect the faulty faucet
To install the new faucet, you need to remove the old one. There are a few steps you should go one by one to achieve this.
1.1. Cut off the main water
Removing the old faucet without cutting the water supply will spill water all over, making it harder for you to either loosen the broken faucet or put a new one in place.
This can be done by locating the supply valve underneath the sink and turning that off.
1.2. Detach the supply line
The faucet must be detached from the water supply line for us to remove it entirely. Then, we can move on to disconnecting the lift rod, taking out the nuts, and finally, the faulty faucet. Remember to take a picture of the original setup to assemble the components later.
2. Take out the drain
If your new faucet doesn’t match the old drain, you should also take the drain out. Start by disconnecting the P-Trap.
Next, dislocate the drain from the sink and remove it (including the sink stopper).
Tips: Prepare a bucket to catch water coming out of the drain.
Make sure to clean all the holes off of silicon sealant. You can easily do this by using mineral spirits.
3. Setting up the new faucet
Before doing the installation, make sure that your new faucet has the same number of holes in the sink. Different types of sinks possess different numbers of holes, ranging from 1 to 3.
3.1. Putting the faucet on
Depending on the type of faucet, you might need to put on the gasket first, before inserting the faucet through the holes. When everything is in place, tighten all the nuts.
3.2. Install the drain and rubber washer back on
You’re now assembling the drain and the rubber washer. Connect them through the top of the sink. Remember to clean up any spilled silicon.
3.3. Install the lift rod
Next, connect the lift rod to the new faucet. Depending on the kind of faucet, you might need to install the ball rod before connecting the lift rod.
3.4. Install the supply line
In this step, you want the supply line to connect to the faucet shanks first. Then, connect the supply line to the valves of the new faucet.
3.5. Turn the faucet on and check for leakage
When the new faucet is installed, turn it on and off to check for dripping or leakage. Take the aerator out, then let hot and cold water run through the new faucet for a minute.
If no leakage is found, simply install the new aerator, and you’re done.
Those are the steps on how to replace your bathroom faucet. It’s not entirely an easy task, and should not be done without prior experience. Call us if you need your bathroom faucet replaced if you don’t want to go through the hassle.
