    What brand faucet? Single or double handle? Does it do it on both hot and cold?

    The most common cause is a loose washer in a double handle valve. Some washerless models develop defects in the cartridge that can cause the same effect.

    I have a Moen, single handle faucet that does the same thing with hot and cold.

This could be something as simple as debris n your aerator

To see if this is the problem remove the silver collar(nut) at the end of your faucet spout by turning counterclockwis (plug the drain holes so nothing oges down the drain) If it is hard to turn put a soft cloth around it and grip with chanel lock pliars or vice grip be areful not to clamp too hard

once you remove the aerator you will see a plastic type of gear and a screen carefully remove thes and rinse with water (look for grains of sand or any obstructions)

before you re install the aerator turn the water on full blast and alternate from cold to hot then together

if this does not work you will need to se if the problem is in the mixing valve which requires removing the cartridge to remove the cartridge:

turn water off under sink(hot and cold)
look for an erasure side cap or cover located at the base of the fauet handle and remove with a sharp screwdriver

take a hex rench (you may need a fashlight) and remove the hex screw then take the handle off
take a channellok wrench and turn the cap nut (large washer type of nut) this will allow you to remove the cartridge
Remove the cartridge and inspet for debris
go under sink and trn water on slowly to flush any debris then turn water off
reinstall cartridge( it is usually keyed )
be sure to snug the nut down but not extremely tight

Reinstall handle and check faucet before you put the set screw in .

This should stop the pulsating if not replae the cartridge


Before you reinstall the

My kitchen faucet is loss from the bottom and it seems it can not be tightened. The water facet water valves seem to be in the way.

Tightening the nut on a faucet is tough to do in the tight space you have to work with. The proper tool to use is called a 'basin wrench' and is not too expensive. It has a swivel head to let you get it up to the nut and turn it from below. Here's a picture:

Valve in Delta faucet closes as water warms up

Yes, you are on the right track, but Deltas use a fancier kit inside them. It is quite a bit pricier than an O ring, but will solve the problem. It is not hard to install at all.

Loss of pressure in kitchen faucet - Price Pfister

Your problem is a simple one.

  1. Turn off water to faucet.
  2. Place a towel(s) in the base of the sink(s) to prevent any parts from going down drain.
  3. Remove the handle to the faucet. (single handle only)
  4. If not a single handle then remove spout from faucet.
  5. If a single handle remove cap carefully and any loose parts.
  6. Gently turn spout side to side while lifting to remove.
  7. You will see a hole with a very small valve where the water comes out to the spout on the base of the faucet.
  1. Remove this valve (which is a backflow preventer) and replace.
  2. Reassemble and test.
Problem solved.
