What Causes A Leaky Bathtub Faucet?

How To Fix A Leaky Bathtub Faucet Single or Double Handle - ResisSoriesIdentifying the problem is the first step if you want to find a solution to anything. Knowing the problem cause of the bathtub faucet you have own will help you deal with it appropriately. Different things can make your faucet drip. Whatever the leakage's trigger is, the seals and the ‘O’ are the affected parts. Once these two components are destroyed, they become incapable of holding water in pipes.

The leading causes of a leaky bathtub faucet are:

Tools And Materials You Need

  • Screwdriver
  • Adjustable wrench
  • Bath socket wrench
  • Handle puller
  • Seat wrench
  • Utility knife

Fixing A Leaky Single Handle Bathtub Faucet

Locate the screwdriver

There a decorated cover at the bottom of the handle. Using a flathead screwdriver, remove the lid and leave the screw under it exposed.

Take off the handle

Remove the exposed screw using a screwdriver. It’s now easy to remove the handle. If it doesn’t come off, heat it with a hairdryer. Alternatively, pour hot water on it to make it lose. Avoid using force if you don’t want it to break.

Unscrew the escutcheon

Some handles have a decorative collar behind the handle. A collar might have also been fixed on the screwed part of the faucet. If so, unscrew them.

Ensure you put the screws in a safe place, maybe in a container. The screws and nuts shouldn’t be misplaced because they’ll be needed when making the replacements. Also, keep note of the order you are using to remove them for easy reconnection after finishing your project.

Take off the packing nut or stem bonnet

Use a bath socket wrench or vice grip to remove the remaining bonnet. Turn the counter sideways until they come off.

Remove the stem

It only requires pliers and a little bit of pulling to take out the faucet’s stem. Grip it clockwise to loosen it quickly.

Check the removed parts and remove the mineral deposits

Look for any corrosion, hard water deposits, or damage on the stem and packing nuts. If you are uncertain of the destroyed parts, then replace all of them. The mineral deposits can be removed by pouring white vinegar on their surface. Leave them for a short while, and then brush them off using a scourer.

Inspect the seat for damage

The washer on the downside of the stem rests on a seat, a tiny tubular sewed part that is positioned inside the faucet. It gets damaged when the washer wears out. Use a seat wrench to remove it.

Replacing The Parts
