Causes of Low Water Pressure | Boston Plumbing

August 26, 2016

Low water pressure can be caused by a number of factors, but it takes the keen eye of a professional plumber to determine the exact reason. Daily activities like showering or washing dishes can be absolutely time consuming and stressful due to low water pressure.

Take a look below at some common causes of low water pressure.

Partially Closed Valves

Sometimes all you need to do is adjust a few valves but this only occurs when a partially closed water meter valve, main water shutoff valve or water supply valve is stopping water flow. While you may have these adjusted counterclockwise, contact our plumbers to regulate water pressure.


If a water main is damaged, debris can get into the pipes which can stop water flow in the pipes, faucets and showerheads. Even the smallest amount of debris can decrease the water pressure. We suggest cleaning the faucet or showerhead aerators to fully remove the buildup.

Corroded Water Pipes

Pipes will typically start to corrode after 20 years and this will happen from the inside out, in turn, blocking the water flow. The only way to remedy this situation is by replacing the pipes.

Municipal Water Supply Issues

In some instances, your entire neighborhood could be experiencing low water pressure due to the municipal water supply. The upside to this is that you don’t need to worry about paying for the repair!
