Clogged aerators and clogged cartridges are two of the most common causes of low water pressure in a sink. The aerator is the tip of the faucet that the water comes out of, while the cartridge is found underneath the sink handle and enables you to stop and start the flow of water.
If the kitchen is the only tap with low pressure, it's time to consider the potential causes of low water pressure in a kitchen sink so you can determine what might be causing it, and fix it. The most common causes of low water pressure in a kitchen sink are a clogged aerator or a clogged cartridge.
Sediments, mineral deposits, or small debris can clog the aerator over time, which results in low water pressure. To restore water flow due to a clogged aerator, use pliers to remove the aerator from the faucet, scrub it with an old toothbrush and rinse in water.
Remove and clean the faucet aerator thoroughly, or replace it with a new one. Remove and clean the flow restrictor, increase the size of the flow restrictor hole, or remove it entirely and replace the aerator without replacing the flow restrictor.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter. If your pressure gauge reading was low, make slight adjustments to your regulator.
One of the most common causes of low pressure to a kitchen or bathroom sink faucet is debris or mineral buildup in the aerator. The aerator is the tiny screen that you see at the end of your faucet.
Since the EPA limits water flow at 2.2 gpm, most modern faucets now come with a pre-installed aerator that limits the flow to 2.2 gpm while also infusing the water stream with air to reduce splashing.
Indoor faucets usually have aerators at the tip. This small but valuable part consists of a mesh responsible for the consistent water flow. Since it controls water pressure, it reduces water splashing in the sink.
Please keep in mind that all new faucets since 1994 are restricted to conserve water per EPA code mandates. Older faucets had no restrictions. Beyond intentional flow restriction, new installations can sometimes have reduced flow if the lines are not flushed prior to installation of aerators or shower heads.
Typical Faucet Flow Rate: How Much Water per Minute Does a Faucet Use? In the United States, the maximum flow rate for bathroom and kitchen faucets is 2.2 GPM with a pressure of 60 PSI. Throughout the globe, faucets are said to have a flow rate of 1 to 2.2 GPM.
A low-flow fixture is a water saving plumbing fixture designed to achieve water savings by having a lower flow rate of water or a smaller quantity per flush. Some of these low-flow fixtures are faucets, showerheads, and toilets.
Low pressure is the most common sign of a clogged aerator, but sometimes the faucet can also misdirect water, spraying it on the side of the sink or even onto the vanity.
Other debris can build up on the aerator, too. It's important to clean faucet aerators and screens to remove any debris from them. How often should I clean aerators? It's recommended you replace the aerator annually, and then clean the aerator twice a year.
Your faucet cartridge sits deeper in your faucet than your aerator and has a hole through which water passes. These cartridges become clogged or blocked by hard water build up which produces low water pressure in kitchen faucets. Often, they just need to be cleaned. This is another relatively easy DIY fix.
Usually, the aerator is screwed on tight and can simply be unscrewed and removed quite easily. In other cases, though, the buildup of mineral deposits may freeze up the aerator and make it hard to remove.
Materials You'll Need
Fill a plastic bag with half water and half vinegar, ensuring there is enough liquid to submerge the faucet head. Put the liquid-filled bag over the faucet head and secure it with a rubber band. Let stand for 30 minutes to one hour. For more sensitive fixture finishes, do not surpass 30 minutes.
Soaking the aerator in vinegar will loosen some of the grime. You can soak it as long as you want, but even five minutes will help.
Depending on the environment, usage, and maintenance, a pond or lake aeration system should last over 10 years. Of course, sometimes there are outside forces that may shorten its life, like power surges and lightning strikes or flooding. But the average lifespan has been seen to be 9-13 years.
