Shut Off the Water Supply

The first step is to turn off the water supply to the bathtub. This is usually located under the sink or near the water heater. Once you have turned off the water supply, you can disconnect the water supply lines from the faucet.

To disconnect the water supply lines, you will need to use a wrench to loosen the nuts that connect the lines to the faucet. Be careful not to lose the washers and O-rings that are located under the nuts. Once the nuts are loosened, you can disconnect the lines from the faucet.

Remove the Old Faucet

Now that you have disconnected the water supply lines, you can remove the old faucet. To do this, you will need to use a wrench to loosen the nuts that connect the faucet to the sink. Be careful not to damage the sink. Once the nuts are loosened, you can remove the faucet from the sink.

Install the New Faucet

To install the new faucet, you will need to reverse the steps you took to remove the old faucet. First, you will need to attach the new faucet to the sink using the nuts that you removed from the old faucet. Once the faucet is attached to the sink, you can reconnect the water supply lines.

Be sure to tighten the nuts that connect the water supply lines to the faucet securely. You should also apply a small amount of plumber’s tape to the threads of the nuts to prevent leaks.

Test the Faucet

Once you have installed the new faucet, you should test it to make sure that it is working properly. Turn on the water supply to the bathtub and check for leaks. You should also check the temperature of the water to make sure that it is not too hot or too cold.

If the faucet is not working properly, you may need to adjust the washers or O-rings. You may also need to call a plumber to fix the problem.

The first step is to turn off the water supply to the faucet. This can usually be done by turning a valve located under the sink. Once the water supply is turned off, you can proceed to disconnect the water supply lines from the faucet.

Disconnect the water supply lines from the faucet.

The water supply lines to the faucet are usually located under the sink. They are typically connected to the faucet with a compression fitting.

Loosen the nuts that hold the faucet in place.

The next step is to insert the faucet into the sink. The faucet should fit snugly into the sink. If the faucet does not fit snugly, you may need to use a hammer to tap it into place.

Tighten the nuts that hold the faucet in place.

Once the faucet is inserted into the sink, you can tighten the nuts that hold it in place. To do this, you will need to use a wrench. Tighten the nuts until they are snug.

Connect the water supply lines to the faucet.
