A faulty shower faucet can cause a significant inconvenience for anyone. You may try to turn the knob to no avail or encounter water leaks, which can escalate your bills. Avoid the inconvenience and save money by fixing the issue. Replacing a single-knob shower faucet can be a daunting task, especially if you lack the technical know-how, but it’s achievable if you follow the steps. This guide aims to provide a step-by-step process on how to replace a single-knob shower faucet.
Turn Off The Water And Drain The Faucet
Before doing anything else, ensure you shut off the water supply to the shower faucet. The water valves can be located under the sink, the access panel, or the water main. Turn off the hot and cold water valves. Next, turn on the shower faucet to drain out any water left in the pipes.
Unscrew The Handle
After turning off the water supply, unscrew the handle covering the valve stem. Use a flathead screwdriver to remove the handle. If the knob is tightly attached, apply some lubricant and leave it to sit for a while before opening.
Remove The Valve Assembly
Underneath the knob, locate the valve assembly. Unscrew the retaining nut before pulling out the valve assembly. If you encounter difficulties while removing it, use a pair of pliers to grip the nut tightly and turn it in a clockwise motion. If the nut is still too tight to remove after applying pressure, you may need to purchase a handle puller.
Install The New Shower Faucet
Ensure the new faucet is the right fit for the old assembly before proceeding. Apply some plumber’s grease onto the valve assembly before fixing the new faucet. Align the faucet holes with the retaining nut before tightening using a wrench. Reattach the handle onto the valve system, then turn the nut clockwise until tight.
Turn On The Water Supply
After fixing the new faucet, turn on the water supply, and let the water run for a few minutes. Check for any leaks or issues with the water pressure. When satisfied that everything is working appropriately, turn off the shower faucet to stop the water flow.
Final Thoughts
Fixing a single-knob shower faucet is a simple task that may not require a professional plumber. By following the steps mentioned above, you can quickly replace a shower faucet on your own. However, if you experience any challenges or don’t have the relevant equipment, hire a certified plumber to help you out. Remember to turn off the water supply before starting any repairs to avoid water damage.
