You need to replace the faucet seals.

It's pretty easy when you find how to do it... I found that video that visually helped me... (http://eurostream.ca/FR/ez_conx_supplyline.asp) if you look into that "easy connector" you'll see a small piece of transparent plastic that the copper can fit into it... but that piece should be removed from manufacturer because it is not needed. So, you have to remove the piece of plastic using a little knife if you want to push it like on the video. As soon as you remove that and you push it enough, you will finally heard that little "click"... So that means that it is on place.Good luck

Usually, it is caused by a worn out o-ring.

Have the same issue. No one seems to have an answer, including KWC (except to buy a new $90.00 cartridge).

Try cleaning the aerator and if that does not fix it then you will have to rebuild the faucet. That means a new cartridge.

There is a set screw under the handle lever maybe covered with a small cap or bottom type cover. remove that cover if it's still there and loosen the set screw and pull the handle off.

on most of the single handle faucets there is an erasure like button ( may have a hot and cold blue and red indicator or be silver ) usually located right under the faucet arm on the manifold chrome sleeve or back behind the arm or it could have a large ring nut over the doam of the lever take your hand and feel the area that covers the area where the spout arm swivels and feel for the button or take your fingers and fel the to of the lever doam

if you find the button just take a sharp screw driver( be sure to plug the drain holes and turn hot and cold water off under sink) pry the button off and use a hex wrench and loosten

if no button then there has to be a large nut on top you may seee two grooves oppsoite each other wheich would mean a special tool

use an adjustable wrench (put cloth ofer chrome to protect and turn counter clock wise( the ring nut will not be very thick

after removing you should be able to replace the cartridge

good luck

That faucet has been discontinued so you may be able to get help here http://www.danze.com/contact_us.asp

Just in case you need to do so.

1. Turn the water off. The water control knob is located under your sink and is connected to the drain. Turn it counterclockwise to turn off the water.
   

2. 2

   Open the faucet to relieve any differences in pressure. Pull up on the faucet as you would if you were turning it on.
   

3. 3

   Plug the drain of the sink with its stopper to prevent any parts from going down it.
   

4. 4

   Turn the faucet handle sharply to one side to reveal a small cover plate. Pry the plate off carefully with a flat-bladed screwdriver.
   

5. 5

   Unscrew the screw that is located behind the cover plate with a 4 mm allen key.
   

6. 6

   Lift the handle off and remove the cap beneath it.
   

7. 7

   Firmly grip the exposed cartridge with your hands and pull up to remove it.

I would get the repair kit before you start. The video below is not your brand faucet but the o-ring replacement is about the same. http://www.youtube.com/watch?v=AipEYoYiIhc

there should be a center nut up underneath, if not how old is your faucet??

replace diveryer valve

Sounds like the retaining ring under the handle may need to tighten a little to stiffen lever a little. To remove handle take plastic red/blue cap at base of lever covering the screw. Remove allen screw that holds handle to base with a allen wrench.

Try to tighten collar that holds the stem for the lever and that should help with the lever. if not the gasket that's under the collar maybe wore to the point that tightening want effect it.

Check out this web site for a view of your faucet. It has a nut that tightens up to the bottom of the faucet's base to secure sprayer to it.

Hello
First shut off water to faucet.There should be a allen screw that holds the faucet together near the top back of the handle,lossen this and pull top off.

Next take some pliers and tighten down the lock nuts to compress the washers,do this gently.

Reassemble,water should stop leaking.

The USUAL cause of this is the diverter valve that channels the water to the sprayer. There are several types of these so search for yours in google to find a blow-up drawing of it. They are usually in the tower the spout swings on and sometimes are a pintle valve like a little rod with dumbells on the ends. Crud can make them not seat then they will cause the hammering.

it ahs to be tightened from under neath the sink.

First you have to remove the main lever/handle. This is done by loostening the allen head setscrew at the pivot point front base of thge handle. Underneath you'll see a collar or nut that is easily removed with a pair of Channel Lock pliers (adjustable) then after marking the front of the valve with a permanent marker(just make a dot) so it is assembled the same way, pry out the valve and repair or replace it, Thank you, Dana.

Should be a little round button to pry out at lower part of handle itself, and likely an Allen key behind it to loosen off and remove, or tighten to snug up handle.
