How to Fix a Leaking Bathtub Faucet?
1. Close the water inlet valve
Remove the small screws on or behind the handle of the tub mixer to remove the handle attached to the body of the mixer. Some screws are hidden under metal buttons, plastic buttons, or pieces of plastic that snap or screw into the handle. All you have to do is flip the button open and see the top-mounted handle screw. Use some grease to loosen the screws if necessary.
2. Remove the handle
Use a wrench to remove the nut, being careful not to scratch the metal. Unscrew the spool by turning it in the same direction you turned it when you turned on the bathtub faucet. Look at the parts of the tub faucet.
3. Remove the screw fixing the seal
If necessary, use penetrating lube to loosen the screws. Check the screws and spool, and replace them with new ones if damaged.
4. Replace the old seal with an identical new one
A new seal that matches the old one almost exactly will generally keep the faucet from dripping. You also notice if the old seal has an angle or is flat and replace it with a new one of the same. The sealing ring designed only for cold water will expand violently when hot water flows through it, blocking the water outlet and slowing down the flow of hot water. Some seals will work in both hot and cold water, but you want to make sure that the one you buy for replacement is the same as the original.
5. Install the bathtub faucet parts
Fasten the new seal to the cartridge and reassemble the parts in the bath mixer. Rotate the spool clockwise. After the spool is in place, reinstall the nut. Be careful not to scratch the metal with the wrench.
6. Water detection
Reinstall the handle and put the button or disc back on. Turn the water supply back on and check for leaks.There are many reasons for the leakage of the bathtub faucet. We need to find out the cause before we can better repair the bathtub faucet. Although the price of the bathtub faucet is not expensive, we also need to take care of it frequently. In the process of using the bathtub faucet, if you want to open it, you must move slowly, so that the bathtub faucet will not risk the handle falling off. If you often open the faucet quickly, it may not stop the water flow and cannot be closed. Tips, if the bathtub faucet is blocked, just clean the spout aerator and use it.
