How do you stop a Peerless faucet from dripping?

If your Peerless faucet is leaking from under the handle, it’s usually because the retaining nut holding the cartridge or ball valve is loose. To access it, you have to remove the handle and the dome-shaped collar, then you can tighten it with pliers. You shouldn’t have to turn off the water to make this repair.

How do you tighten a peerless faucet?

Insert your Peerless faucet through the escutcheon in the mounting hole, and secure the valve with the gasket, washer, and the threaded nut on the mounting shank. Then, hand-tighten the nut onto the shank. Lock the nut into position by tightening the screws with the Phillips screwdriver.
