How to stop tub faucet from leaking

If you notice that your bathtub faucet is leaking or is dripping, you are not alone. This is a commonly occurring problem that ends up happening in most homes at least once throughout their lifetime. So don’t worry about it. Here we provide complete solution of how to stop tub faucet from leaking.

A leaking bathtub faucet is usually caused by an old washer. The washer helps create a watertight seal, which is why it pushes up against the faucet seat as the faucet handle moves.

Friction between the washer and faucet seat as the water taps turn wears out your washer, which makes it prone to breaking down and causing a drip or trickle.

If your faucet is leaking while you’re in the shower, it’s a bad diverter. Handles on faucets may not pop up by themselves so you have to do that manually when you want water to just be coming out of the fixture sprayed by a sprayer head; turning the handle upwards or clockwise will actually ask for water to come out of both the spout and the head.

It might seem easy enough, but some handles are designed to fool people into believing they are meant to be pulled horizontally – left if looking at it from behind when it can actually only be moved upwards.

When you want water to flow out of the tub faucet, you turn it in the direction opposite of that which comes from the showerhead – a move that pushes the rubber spout seal against both the porcelain spout and the showerhead, causing it to wear out over time.

When hot water comes into contact with the rubber seal instead of cold, this accelerates deterioration even more.

To fix a leaking bathtub faucet, you need to replace both the faucet washer and seat. It is important that you replace the seat because a worn-out washer means that there is a metal-to-metal interaction between the stem and the seat, causing the seat to burr. A burred faucet seat will tear a new washer and the bathtub will start to leak again.

Some common Causes of bathtub faucet leaking

There are many causes for how they leak. Now here, are some important causes we are going to mention here.

Damaged cartridge

If you have a valve with two different ways of controlling the flow of water, one that controls hot water and the other cold water; then it is likely a cartridge-style faucet. The cartridge is what controls the amount of water flowing through the faucet spout. If your faucet is dripping, this probably means that the cartridge needs to be replaced since it may have sustained an adverse effect on its structure.

A washer is broken

A common cause for a running tap can be washers. Either a washer is the wrong size or does not seem to be seated securely, it can cause a leak as it falls out of place. Change them depending on how worn out they are and test the tap.

Ball Faucets

These faucets use a ball joint to control hot and cold waterlines. They’re characterized by a single handle on a rounded cap mounted on top of the spout. To work them, you push up and down to adjust the pressure (meaning how much water comes out), left or right to adjust the temperature, then rotate it straight ahead when you’re satisfied with your adjustments. They can be used in kitchens and other high-use areas.

A deteriorated value seat

If you have water constantly dribbling from the spout of your faucet, the problem could be caused by a valve seat. The seat connects the faucet to the spout and prevents debris from entering the piping system and causing damage. Sediment can gather around the edges of this part or even corrode it entirely, causing leaks.

How to stop tub faucet from leaking

Step 1

You can probably turn off the water to your bathtub in a couple of ways, but if not, you should find the main supply valve to your home and turn it off. It might be best to go outside and cut the water at the next stop within your house’s system. People who have older homes can usually find their home’s shutoff valve by looking on a wall in their basement next to whichever pipes take cold water into their home.

Step 2.

Use a flat and short screwdriver to pop the handle buttons from their respective faucet handles. With those removed, you will be able to see the screws for the individual handles. Use a Phillips screwdriver to remove these screws and using whatever means possible, pull the handles off of the stems inside of the sink.

Step 3.

Stand under the showerhead and turn off the faucet at the mixer valve to drain any water from the pipes involved. Remove the showerhead by turning it counterclockwise until it won’t come further out, then set it aside. Insert a swivel accent lever screwdriver into one of two ¼-inch holes on either side of the home base. Use force to push up while simultaneously turning counterclockwise in a twisting motion until the valve pops off.

Step 4.

Insert a wrench into the openings left by the old seats. Then turn the wrench counterclockwise to remove them. Apply some liquid sealant on the threads of the new seats and insert them into the openings so that they tighten clockwise onto them to secure them.

On the end of each stem, seat washers must be secured by screws. By loosening the screws with a screwdriver, one can remove the old seat washers and install new ones into their place before tightening the screws again.

Step 5.

Cover the threads of the stems with thread sealant. Then, place them inside the openings of the faucets. Use the stem sockets to turn them clockwise and tighten, using the plumber’s putty if needed. Cover the stems with faucet handles.

Secure the faucet handles with the handle screw. Hold the handle button back over the faucet handles to cover the patch. Turn on the water supply to the bathtub faucet.
