Identify Leak Source
Start by turning off the water supply to the faucet. Check the faucet handlefor any loose parts or worn-out seals that may cause leaks. Tighten the handle if it feels loose or replace the cartridge inside if needed.
Next, inspect the spout and base. Look for cracks or worn-out washers. Sometimes the spout can wear down and cause drips. Clean any mineral buildup that can block a proper seal.
Finally, examine the water supply lines. Check for any visible cracks, leaks, or loose connections where the lines meet the faucet or shutoff valves. Tighten or replace faulty supply lines to stop leaks.

To start, gently remove the handleby loosening the set screw. This gives access to the faucet’s inner parts.
Next, pull out the cartridge or valve. It controls water flow and often causes leaks.
Carefully examine the cartridge for any damage or wear. Replace if necessary.
Use a soft brush and mild cleaner to clean all components. Dirt and buildup can cause leaks.

Replace And Reassemble
Replace the old cartridge or seals with new ones that fit your Delta faucet model. Make sure the parts are clean and free of debris before installing. Gently push the new cartridge into place, ensuring it sits evenly to prevent leaks.
Carefully reattach all faucet parts in the reverse order of removal. Tighten screws and nuts securely but avoid overtightening, which can cause damage. Check that the handle moves smoothly and the spout is aligned properly.
Turn the water supply back on and observe the faucet closely. Watch for any drops or moisture around the base, handle, and spout. Run water through the faucet for a few minutes to confirm there are no leaks.
