What Causes Low Water Pressure in Bathroom Sink?

Low water pressure in the bathroom sink can be a frustrating issue that can make everyday tasks difficult. Understanding the causes of low water pressure can help you troubleshoot and resolve the problem.

Faucet Aerator Clogged

The faucet aerator is a small screen located at the end of the faucet spout. It helps to control the flow of water and prevent splashing. Over time, the aerator can become clogged with minerals and debris, which can restrict water flow and reduce pressure.

Pipe Corrosion or Blockage

The pipes that supply water to your bathroom sink can become corroded or blocked over time. Corrosion can narrow the diameter of the pipes, reducing water flow. Blockages, such as mineral deposits or sediment, can also restrict water flow and cause low pressure.

Water Pressure Regulator Issue

A water pressure regulator is a device that helps to control the water pressure in your home. If the water pressure regulator is not functioning properly, it can reduce the pressure to your bathroom sink.

Shower Diverter Valve Malfunction

If your bathroom has a shower and sink that share the same water supply, a malfunctioning shower diverter valve can cause low pressure in the sink. The diverter valve is responsible for directing water to either the shower or the sink. If the valve is not working properly, it can restrict water flow to the sink.

Cross-Connected Plumbing

Cross-connected plumbing can occur when two different water sources are connected to the same plumbing system. This can cause water from one source to flow back into the other source, which can reduce water pressure in your bathroom sink.
