The A-S single lever kitch faucet is terrible. If it is the one I think it is, then it has three screws that mount the cartridge down into the faucet body.If these are not torqued perfectly evenly, the faucet leaks. I suggest getting a Moen to replace it.

Hi! If there are no leaks from around the spout, you can remove the spout and apply silicone lube to the spout o-rings and resemble. If it is still hard to move ,replace the o-rings.

If it is a single hole faucet, there should be a single nut on the threaded brass piece underneath the sink. You may need a basin wrench to get access to it if you cannot get to it with an adjustable jaw wrench. This nut normally clamps against a U shaped washer that is against the underside of the sink.

First, turn off the water supply under the sink. Next, put the faucet lever in the up position, no water should be coming out. While in the up position turn slowly while looking at the underside of the handle and you should be able to find a set screw. It will probable be an "allen head" type and you will need and allen head wrench to loosen it. An allen head looks like a hex shape, 6 sided I believe and is rod shaped. If you don't have one they come in sets at your local hardeware.

You need to remove the plug on the handle itself, and there will be a screw underneath it. With this screw removed you will be able to remove the handle. Hope this helps

replace the faucet,sounds like it has gone bad.

you must remove the faucet form the sink. under the plate in the middle is 2 screws. remove the screws to remove the body.

at the spout near the base is an echeion ring. turn this counterclock wise then pull up ring to expose the neck,pull spout straight up.this echeion cap holds on the spout to the base there are plastic parts inside so be careful when pulling apart.

After you remove the handle, the chrome cap should either snap or spin off.It also may come out with the cartridge... There are 3 screws that hold the cartidge in the faucet...take them out and you should be able carefully work the faucet are off of the core of the faucet. Put a little cooking oil on the o-rings after you install the new ones... just to allow the faucet arm to slide on without damage... Hope this gets you dripless!! Let me know if you have a question. K
