If a Delta faucet is leaking from the spray head, first remove and clean the diverter assembly. If the problem continues, replace the spray and hose assembly. If the faucet is leaking from the base of the spout, the

O-rings might be defective and should be replaced. To replace the O-rings, remove the faucet handle and cartridge, and then push the top O-ring off the spout to remove it. Lift the spout up, and remove the O-rings at the bottom of the faucet base.

If the faucet is leaking from the aerator, the stem unit assembly might be damaged. The stem unit assembly is irreparable and can only be replaced. If the problem continues, check whether the seats and spring are worn out, and replace them accordingly. If the faucet is leaking from the handle, tighten the handle. If the leak persists after tightening the handle, replace the stem and unit assembly.

If the Delta faucet has stopped leaking, but it clunks after switching it on or off, there might be high or low pressure in the house. Contact an experienced plumber to help remedy the problem.
