How to Fix a Leaky Bathroom Faucet

The type of repair you will need to do on a leaky bathroom faucet will depend on the leak you are having. If there is dripping from the spout, then you will need to do a repair on the faucet. First determine what brand of faucet it is – it will have a mark on it somewhere or may even be on the pop up stopper. You may need to change a cartridge, stem or even a ball. Washers and seats may also need replacement instead of the stem itself. Moen uses cartridges, American standard uses stems and cartridges. Delta uses cartridges, balls, and seats and springs. Grohe needs ceramic cartridges and Price Pfister could need a cartridge, stem or may just need seats and washers. If water is leaking constantly below the countertop or around the base of faucet with it operational or not you will more than likely need to replace the faucet, but you need to do some troubleshooting first. Look to see where the water is coming from and then you will know what you need to do. There will be handles to remove by removing a button or a cap, then removing a screw or set screw. There could also be a retainer clip or a nut or bonnet. There may even be an escutcheon that needs to be removed. Once you get to this phase you can remove the assembly and see if you need replacement or if the faucet just needs some washers. Before you perform any part removal, make sure that the water to the faucet is turned off. There will be some angle valves below the counter top to turn off the water. If those valves do not hold then they should be replaced and you will need to shut the water off at your main valve.
