How to Fix Leaky Delta Bathroom Faucet: A Comprehensive Guide to Repairing Your Delta Faucet

Fixing a leaky Delta bathroom faucet is a straightforward DIY project that can save both water and money. Most leaks originate from worn-out washers, O-rings, or cartridges inside the faucet. Before you begin, gather basic tools like an adjustable wrench, screwdrivers, replacement parts specific to your Delta faucet model, and plumber’s grease. First, shut off the water supply under the sink and plug the drain to avoid losing small parts. Remove the handle by loosening the set screw—usually hidden under a cap. With the handle removed, you can access the inner assembly: for a compression faucet, locate and replace washers or seats; for cartridge models, take the cartridge to your local hardware store to ensure an exact replacement. Clean any mineral buildup before inserting the new parts, then reassemble the faucet. Turn on the water supply and check for leaks. If problems persist, consulting the manufacturer’s manual or a professional may be the best option.
