Leaking Out Of The Waterfall Faucets End - -Make sure to turn the water off before removing the faucet stem! Continual leaking from the faucet after it is shut off is caused by bad washers at the end of the valve stem.Use a screw driver to remove the screw holding the washer and valve parts onto the end of the valve stem. Roll the washers off the stem and then install the new washers in the same order and direction. Put the valve stem back into the Automatic Faucets and tighten the packing nut.
