Low Water Pressure in Kitchen Faucet

About two weeks ago, I noticed a decrease in the water pressure coming out of my kitchen sink faucet: about 50%. Since then the pressure has not decreased any more but is still WAY TOO LOW.

Please help...THANK YOU

    I have the same problem but is not the aerator or the diverter. I have put in a new cartridge. Hoses are fine and there is plenty of pressure to the faucet. The water pressure starts a little low but after a few seconds it starts slowing down

    I have the same problem. It is not the aerator screen. Pressure is good. It's a mystery.

    I have same problem, but when I take off the screen the pressure still is low. Doesn't seem to be the screen at the end of the faucet.

    Grohe Ladylux - extremely low water pressure.  It's only 3 weeks old.  pressure to the faucet is great, but when it reaches the spout/spray nozzle, forget it.  Barely a trickle.

    I have the same problem. Low water pressure on cold only. Plenty of pressure at the supply valve. I also removed the cartridge, but everything looked clean. And no, it's not a clogged screen, which would affect both hot and cold. Help!

    Ladylux pro with low water pressure one day after installation. Now we know it is not clogged because plumber checked is a mystery, can anyone help??

    After replacing the cartridge just a few months ago, the water has dwindled to a very slow flow. The sprayer is not much better. I suppose I could try cleaning the screen, or put in another cartridge, but I may just replace the whole system. It's pretty, but worthless!

Ihad the same problem. It is not the screen. What you need to do is get a spray diverter the old one disintergated and is blocking the flow. You have to take the collar off and underneath is the diverter. This is after you take the ball and rings out.

    Had the same problem! And, yes, I too found that it was the diverter. To reach the water shutoff valves, I used this tool:

The filter screen in the faucet is probably clogged, Use pliers covered in a pair of dishwashing gloves ( so your won't scratch your faucet) and remove the tip of the faucet where the water come out. Clean the screen and you should be back to 100%. If it's because of mineral build up, you will have to soak the piece in lime-away.

Low water pressure

Remove the spray head and point the hose into the sink drain. Turn the faucet on. If you have good pressure, cal American Standard for a free replacement spray head.
If you still have low water pressure without the spray head, ask them for a new faucet cartridge.
After replacing the faucet cartridge, if you still have low water pressure you will need to ask for a new faucet, possibly free if yours is still under warranty.

I have a Grohe Ladylux Plus and the water pressure was good till about 6 weeks ago. Now I have very low flow in kitchen. What do I do?

If it is just this faucet and no others then it is likely the filter screen in the tap head is clogged.

Remove the cover from under the tap head. Pries off from the tap head directly where the water comes out.

There is a metal mesh screen there. It will be full of white chalky deposits from minerals in the water supply. Clear that out and you will be good to go.

You will also want to clear the holes for the spray pattern. The same deposits will be there.

Good luck.

If this helped give you some direction please rate the answer for me.

The hot water side has low water pressure. The

start by making sure the valve that supplies hot water to the sink and dish washer is fully open. If there is low hot water pressure in any of the other kitchen/bathrooms, then trace the line to see where the pressure drops. If it is only in the kitchen, it should be an old valve, (causes restriction)Good Luck.

Check the screen at the hose connection under the sink. Check the hoses for any large debris in them. Verify that the water pressure coming from the water outlets under the sink is good. There is obviously a restriction just need to locate it.

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.
