Low Water Pressure in Faucets

ow water pressure in faucets is a very common problem. The source of a slow or clogged kitchen faucet can almost always be found inside the faucet. It usually takes a small amount of effort to get the water flow back to normal.
If you have noticed the water pressure coming out of the kitchen sink drop in pressure and get worse everyday but all the toilets fill quickly and all other sinks are fine. Then you need to change the cartridge in the sink faucet.
If you take the aerator apart, you will discover extremely small holes in round disks made of plastic or metal. The water flowing from the faucet must pass through these tiny orifices.
The drop in water volume and pressure at the two faucets was caused by small pieces of sediment or some other debris that clogged a passageway within the valve cartridge and/or the tiny orifices within the aerator and or a flow restrictor.
The sediment can form within a faucet or its parts depending upon the hardness of your water. Sediment also forms as a scale on the inside of municipal water supply pipes and the water lines inside your home. Pieces of this sediment can break off and be transported through the water lines as water moves towards a faucet. Small pieces of sand or rocks can enter a water system, especially those of people who use a private well. These can block the pathways within your faucets.
It is not expensive to correct the problem. The first thing I would look at are the aerators in any faucet that is giving you problems. Carefully remove the aerator and pay attention to how the different parts are assembled. Look at the parts, including the screening at the tip of the aerator, to ensure all parts are free of debris and all pathways are clear. Use tiny straight pins to open up any closed holes in these parts. You may have to soak the parts in warm, white vinegar overnight to removed caked, hard-water deposits that can build up within the aerator.
If, after reassembling the aerator, the water pressure and volume are still low, this means the problem is probably in the valve cartridge. The owner's manual that came with the faucet will show you how to remove and replace this common and inexpensive part. If you do not have the manual, try visiting the manufacturer's website for a technical bulletin showing you an exploded view of the faucet and its parts.
