Water pressure problems affecting your home’s plumbing system can be very inconvenient. They make it difficult to enjoy a comfortable shower and may not remove all the gunk from your car when you’re washing it. If you're dealing with this problem, there are many reasons why your pressure might be reduced. To help you diagnose the issue, below are some of the most common causes of low water pressure.

Reasons Your Home May Have Low Water Pressure

1. Closed Valves

Before calling a plumber, make sure your water valves are completely open. If one is even partially closed, it could reduce the amount of pressure throughout the home. One valve is usually located right below the water meter outside your house, and the other might be in your basement or a utility room, located on the exterior wall facing the street.

2. Failing Pressure Regulator

The purpose of a pressure regulator is to reduce input pressure to prevent pipes from bursting. Not all households have one, but if yours does, a pressure regulator failure can result in either sudden pressure spikes or decrease in water pressure. It happens all at once, immediately after the device fails. In a cold-weather climate like Wisconsin, the regulator valve should be located inside the house, between the plumbing entry point and the water heater. If yours looks corroded or cracked, it may need replacement.

3. Clogged or Corroded Pipes

If the valves are fully open and the pressure regulator is working, you may have a clogged or corroded water pipe. If the unit it clogged, it will restrict the flow of water, reducing pressure. If it’s corroded, it may have cracks along the system that are leaking along the way. If you’ve noticed an increase in your water bills, you may be facing the latter issue.
