kitchen faucet suddenly lost water pressureHas your kitchen faucet suddenly lost water pressure. The first thing to do is make sure that it is the only area in your home that the water pressure has slowed. Go through your home and turn on your faucets one by one turn on the cold and hot separately. If they all seem to have a decent flow of water then you can be sure the water pressure problem is isolated to the kitchen sink.

The next thing you need to do is remove the aerator that is on the end of the spout. Often the aerator can get blocked with small particles of debris. After removing the aerator turn the water on without the aerator if the water pressure has picked up then you know that was the issue. Clean off the aerator and put back in the faucet.  Here is a video on how to clean your aerator.

If removing the aerator did not help your problem you could have a blockage. If you have a side spray, does the water come out of it at the expected rate? Is the loss of water pressure the same if you run hot or cold water? Minerals can break loose in your pipes and block the inlet ports of your cartridge.  To fix this shut off the water using the valves under the sink and disassemble the faucet. Pull the cartridge out and clean the inlet ports.  Before reattaching the faucet turn the water on (make sure you have something to cover it) and check the flow strength of the water. If the flow is strong reassemble the faucet and test the flow again. If you still are not getting a good flow of water it is highly likely your cartridge needs to be replaced. Their are numerous types of faucet cartridges so make sure to take your faulty one with you and if you know the make and model # of your faucet write that down and take to the store with you as well.

While your faucet is apart would also be a good time to flush your supply lines. To do this simply cover the base of the faucet with a cup or something similar and then turn on both water valves. This will cause water to shoot straight up from the base of your faucet (see why you needed that cup?) . Doing this will flush most if not all of the debris that may be in your supply lines. Let the water run for about a minute and then reassemble and test your faucet again.
