Reasons behind the Low Pressure in Kitchen Faucet

Cartridge Obstruction

One of the leading causes of the low kitchen water pressure is the cartridge clog. The cartridge is supposed to control and regulate the water pressure in your kitchen. It helps regulate the water pressure through the faucet, but any malfunction may lead to cartridge failure. When it is clogged, it causes the water pressure to fall. 

Aerator Failure

Another reason that leads to the low water pressure in the kitchen faucet is the aerator clogging. The debris or mineral deposits in your water supply lines lead to pressure trapping. After some period, this debris increases to a dangerous level and causes the blocking of the kitchen faucet. 

Water Lines Failures

Sometimes, the breaking of the municipal water lines may lead to a low-pressure problem. To confirm whether the water line breaking is the actual cause of low water pressure in the kitchen or not, check the water pressure in your bathrooms. If you notice a similar problem there, it is confirmed that the water line has broken. 

Leakage Problems

Sometimes, the water supply pipe may leak anywhere, leading to decreased water pressure in the kitchen. It is up to you to locate the exact position of the water pipe leaking. However, this needs a professional touch to get repaired. 

Shut-Off Valve Failure 

To regulate the water pressure in different zones of your home, certain shut-off valves are fixed there. They help to cut the water supply or to regulate it for a certain area. In kitchens, they are usually inserted behind or under the sinks. Any failure to this valve causes total blockage or low water pressure in the kitchen. Moreover, someone may accidentally shut this valve that leads to a water shortage in your kitchen. 99% of the time, these will be the cases for your reduced water pressure.
