Luckily, replacing the O-ring is a simple and inexpensive fix that can save you from a bigger plumbing headache down the road.
Step-by-Step Guide to Fixing a Leaking Delta Bathroom Sink
Step 1: Turn Off the Water Supply
Before beginning any plumbing repair, it's important to turn off the water supply to the affected area. In this case, you can either turn off the main water supply to your house or look for individual shut-off valves under the sink. Once the water is turned off, open the faucet to release any remaining water pressure.
Step 2: Gather Your Tools
To fix a leaking Delta bathroom sink, you will need a few basic tools, including an adjustable wrench, a screwdriver, and a new O-ring. Make sure to choose an O-ring that is the same size as the one you are replacing.
Step 3: Disassemble the Faucet
Using your screwdriver, carefully remove the handle and the faucet cap. Then, use your wrench to unscrew the mounting nut and remove the valve cartridge. You should now be able to see the O-ring.
Step 4: Replace the O-Ring
Carefully remove the old O-ring and replace it with the new one. Make sure to clean any debris or mineral buildup from the area before installing the new O-ring. Then, reassemble the faucet in the reverse order that you disassembled it.
Step 5: Turn the Water Supply Back On
Once everything is reassembled, turn the water supply back on and test the faucet for leaks. If everything is working properly, you should no longer have a leaking Delta bathroom sink.
