Identifying the Source of the Leak

A key step before starting repairs is to pinpoint the side of the leaky delta bathtub faucet that’s causing the problem. This knowledge will allow you to focus your efforts on the correct handle, track outages and protect your bathroom from unnecessary work and potential damage.

But how can you identify the source of the leak? Well, it’s simpler than you might think. All you need to do is feel the temperature of the water dripping from the valve stem. If it’s warm, the leak is likely on the hot side, and if it’s cold, the culprit is the cold side.

Shutting Off the Water Supply

Upon identifying the leak’s source, you must cut off the water supply to your delta bathtub faucet prior to commencing any repair work. To do this, locate the shutoff valves for hot and cold water, which are typically located near the tub or in the basement. Turn the valve handles clockwise to cut off the water supply and prevent any water pressure issues or potential damage.

If you’re having trouble locating the supply valves or if they’re not functioning correctly, you may need to shut off the water supply to your entire residence using the shutoff valve. After shutting off the water supply, double-check that the water is indeed off, and then you can proceed with the repair work, such as installing a new spring.

Removing the Faucet Handle

The first step in fixing your leaky delta bathtub faucet is to remove the faucet handle. Depending on the age of your faucet, the screw or setcrew holding the handle in place may be located on the top or side of the handle. The decorative cap on the top of the handle needs to be removed in order to access the handle screw. This may be necessary before any further action can be taken.

Now that you’ve located the screw or setscrew, use an Allen wrench or Phillips screwdriver to loosen it. Remember to work carefully and gently to avoid damaging the handle or the faucet. Once the screw or setcrew is loosened, lift the handle off the faucet stem to expose the assembly.

Disassembling the Faucet Stem

Once you’ve taken off the faucet handle, you can begin disassembling the faucet stem. Start by detaching the bonnet nut from the delta faucet stem using tongue-and-groove pliers or an adjustable wrench. Turn the nut counterclockwise, unscrew it fully, and remove it from the stem.

Next, remove the stem.

  1. Grip the spindle at the top of the stem.
  2. Pull it straight up and out of its housing. Depending on your faucet model, you may need to use pliers to accomplish this task.
  3. When extracting the stem, remember its position and orientation, as you’ll have to reinstall it identically for the faucet to work properly.

Once the stem is removed, it’s time to extract the valve seat and spring from the faucet. To do this, insert a small screwdriver or Allen wrench into the hole of the seat and pull up both parts together. With these components out, you’re now ready to replace the worn parts and get your faucet back in working order.

Delta Leaking Bathtub Faucet

If you've noticed a persistent issue with your bathtub faucet, specifically a Delta brand faucet, you might be dealing with a “Delta leaking bathtub faucet.” This common problem can lead to wasted water and potentially higher utility bills. A leaking faucet not only impacts your water usage but can also cause damage to your bathroom fixtures and surroundings. 

Replacing Worn Components

When dealing with old seats and springs in a faucet, it’s essential to use the right tools and materials for a smooth process. Begin by applying plumber’s grease to the existing seats and springs, which will make removing them from the faucet easier. Once the old seats and springs are out, it’s time to install the new ones. Fit the new seat and spring in the same orientation as the old one. Attach them onto the end of a screwdriver or Allen wrench. Then apply plumber’s grease to the new seats and springs to guarantee a smooth installation process.

Guide the new rubber seat and springs into the hole in the stem housing using a screwdriver or wrench. Make sure they fit all the way down into the hole, remove the screwdriver or wrench, and verify that the valve seat is properly positioned.

Testing for Leaks and Final Adjustments

Once your faucet is reassembled, you can restore the water supply and check for potential leaks. Slowly turn on the shutoff valves for both hot and cold water, and then carefully inspect the faucet for any signs of dripping or pooling water.

If you notice any leaks, ensure that the bonnet nut is tightened as required. In some cases, you may need to make additional adjustments to guarantee the proper operation of your repaired delta bathtub faucet.

Troubleshooting Common Issues
