Shut Off Water Supply

Ensure the water supply is shut off before you start working on the faucet. Locate the shutoff valve under the sink, on the side of the faucet you’ll be working on (hot or cold). If you’re unable to locate the shutoff valves at under the sink, turn off the water from the main valve. Once the water is completely turned off, open the faucet to release the pressure that’s built up in the supply lines..

With the water supply safely deactivated, you can begin the repair process without any unexpected water mishaps.

  2. Locate the screw or set screw that holds the handle in place.
  3. Use a screwdriver or Allen wrench to remove the screw or set screw.
  4. Gently pull the handle away from the wall to expose the valve stem and other internal faucet components.

By following these steps, you’ll be able to remove the handle and proceed with the rest of the repair process.

Locate Decorative Cap

The first step in removing the faucet handle is locating the decorative cap on the Delta faucet handle. This cap often conceals a screw that holds the handle in place.

Delta Tub Faucet Leaking

If you've noticed a persistent issue with your Delta tub faucet leaking, it's essential to address it promptly to prevent water wastage and potential damage. Leaks can be caused by worn-out washers, damaged O-rings, or other internal components. To tackle this problem effectively, you'll need to diagnose the source of the leak and determine whether a simple repair or a replacement part is required. Regular maintenance and timely fixes can help extend the life of your Delta tub faucet and keep your bathroom in top condition. Don't let a leaking faucet inconvenience you – take action now to ensure a smoothly running, water-efficient bathroom.

Remove the Bonnet Nut

First, remove the bonnet nut that secures the valve stem in place. To do this, use tongue-and-groove pliers or an adjustable wrench to turn the nut counterclockwise until it’s completely unthreaded and can be removed from the stem.

If the bonnet nut is difficult to loosen, applying WD-40 or penetrating oil can help.

Extract the Valve Stem

With the bonnet nut removed, you can now extract the valve stem. Before pulling it out, note its position, as you’ll need to reinsert it correctly during reassembly.

Gently pull the valve stem away from the faucet body, using pliers if necessary for grip.

Replacing Seats and Springs

Leaking kitchen faucets, specifically stem-style ones, are often caused by worn-out neoprene valve seats and springs. Replacing these parts will fix the leak and restore your faucet’s functionality.

We’ll now replace the old seat and spring with new ones, which should resolve the leak.

Remove Old Seat and Spring

Insert a small screwdriver or Allen wrench into the hole of the seat. Pull up both parts together to remove the old seat and spring. Take note of the orientation of the spring within the valve seat, as you’ll need to install the new spring in the same orientation.

Apply Plumber's Grease

Before installing the new seat and spring, apply a thin layer of plumber’s grease to ensure smooth operation and extend the lifespan of the components. This will help prevent future leaks and keep your faucet functioning at its best.

Install New Seat and Spring

Install the new seat and spring into the stem housing, ensuring the spring is oriented correctly.

With the new rubber seat and spring in place, your faucet is on its way to being leak-free once more, just like when you install a new cartridge.

Reassembling the Faucet
