Step-by-Step Guide to Fix Bath Faucet Leak
It is time to learn how to fix the bathroom faucet leaking at the base and get started on your DIY project by following the exact steps given below.
Step No. 1: Disassemble the Faucet
The nozzle handle removal is the most difficult part of the procedure. Corrosion over time may permanently bond the knob to the stem. To drain extra water from the system, turn off the water supply to the nozzle and open the valves. Using a pocket knife’s narrow blade, pry the handle insert out.
Step No. 2: Remove the Handle Screw
Unscrew the handle screw and gently wriggle the handle until it comes out. If it is stuck, use a hair dryer to heat it and loosen it. Be cautious not to apply too much force, as it may break.
Step No. 3: Detach the Handle
The faucet handle can be removed by performing the following steps using a Phillips head screwdriver. Turn the internal nozzle handle screw counterclockwise to loosen it. The handle should then be grasped and pulled straight out to separate it. Don’t worry if the screw is still present inside the handle; it will be removed with the handle.
After that, remove the stem by placing the bath socket onto the stem bonnet and rotating it counterclockwise to loosen the stem. If it’s stubborn, apply penetrating lubricant and let it soak. Finally, unscrew and remove the stem.
Step No. 4: Tighten the Seat Washer
This step is critical in learning how to fix a bathtub faucet leak. Replacing the seat is necessary if leaks occur due to stiffening of the seat washer or erosion of the brass rim caused by water pressure. The seat should be changed using a specialist seat wrench.
The seat can be removed by inserting the seat wrench firmly into its center and turning it counterclockwise until the seat comes loose. In case it sticks, apply penetrating lubricant and try again. Apply pipe adhesive to the threads of the new seat before using the seat wrench to screw it into the fixture body.
Step No. 5: Install New Parts
To reinstall the faucet, collar, and handle, follow these steps: Begin by securing the faucet stem by either screwing it in or pushing in the cartridge or ball until it is firmly in place against the valve. Next, tighten the collar pieces by screwing them back on. Finally, attach the handle back onto the end of the faucet and reattach any decorative plates. If you had to remove any escutcheon plates, make sure to apply a layer of plumber’s putty underneath them to prevent any leaks from seeping into the walls.
If you’re still experiencing leaks even after your previous repairs, it’s time to replace the tub spout. Here’s what you need to do:
- Check the bottom of the tub spout for a screw. If you find one, turn it counterclockwise to loosen it. If there’s no screw, proceed to the next step.
- If the spout is directly screwed into the wall, turn the entire spout counterclockwise to remove it.
- Make sure to remove any old Teflon tape present on the threading.
- Wrap a fresh layer of Teflon tape around the threading.
- Slide on the new tub spout.
- Screw the new spout in by turning it clockwise until it’s securely in place.
- To ensure a proper seal, apply a bead of caulk at the seam where the spout meets the wall.
Keep in mind that the old spout may have worn-out threading, which could cause water to leak. If you change the spout and the nozzle continues to leak, it’s recommended to contact a plumber to identify the underlying cause.
Bottom Line
In conclusion, this article has outlined the exact steps on how to fix bath faucet leak. You can easily apply these steps and resolve the issue. However, if the repairs don’t resolve the leak, consider contacting a plumber to replace the entire faucet assembly. It’s also recommended to call a plumber if the wall surrounding the single-handle valve cartridge is obstructing access.
