How do I increase the water pressure of a kitchen faucet?

Our water pressure is great throughout the house except from the kitchen faucet. We have checked the screens and areators and have found no blockage, still weak pressure. Any other suggestions?

    Check the shutoff valves underneath the sink and make sure that they are fully opened. If that doesn't work, and the fixture is old it could have a lot of internal corrosion and might need to be replaced.

    Since you have done the screens and filters, and I am guessing you have checked that any valves which may be in line are fully open, that leaves the faucet itself or blockage in the pipes feeding the taps.

    Are the feed lines old galvanized, copper or pex? If galvanized they may just have build up inside limiting flow. Pain to do, but replace them. I had a single lever faucet that had an o ring fail, it did not leak in any way, but a piece of the o ring lodge in a hole and reduced overall flow. Pulled it apart, removed the blockage and put in new o rings.

    If you have a newer kitchen faucet, they are all water saving now and have lousy water pressure. We went from one old enough to a new one and it takes forever to fill the sink or a pot with water.

    Adding to what Bmasecar wrote, your hot/cold valves in your faucet (whether single or separate faucets) can easily become clogged with sediment. Take your faucet apart and check to make sure all then openings are clear, and if you have a cartridge type faucet, make sure the cartridge is working properly.

    Yes I agree with all of the above responses, is it new faucet they are very Conservative in water delivery. And delivery lines or water stop valves may have grits at the stop washers clogging the water supply it's kinda hunt an peck on finding the plug; Turn Hot side on then off and then the cold on an off are they the same in pressure. while each side is on separately with a light hammer tap the supply valve with a hammer to see if any change in flow, tap the whole supply line , Hot an Cold then recheck the flow, and if you have chlorinated water supply that will cause o-rings to swell , like i said kinda Hunt an Peck to find a lot of the time. Is the water supply Galvanized, Steel pipe they rust inside a lot. Good Luck Happy Hunting An let us know what you find Regardless to help us to give good advise to others. We all know that all together we may not have the right answer we all are always looking for that ! TR.
