Water Pressure Low? 4 Causes and Solutions | Calhoun Plumbing

Low water pressure can be an irritating problem. It makes showers less enjoyable and makes it harder to get things clean. Low water pressure can also make some jobs take longer, like watering plants outside. If your home has low water pressure, whether it’s in one localized area or all over the house, the problem is worth fixing. Once you know some of the causes, you can decide what to do about it.

Low water pressure can have many causes, so if your home has this problem, you’ll need to investigate. Some of the most common causes of low water pressure are easy to fix, but some may require you to make big plumbing repairs or installations.

1. Clog in a Fixture

As sediment travels through your pipes, it can cause a clog in a single faucet or pipe, leading to low water pressure in a localized area of your home. Sometimes this sediment becomes trapped in the faucet opening where the water aerator is located. If this happens, simply unscrew the aerator and remove the sediment to fix the problem.

Other times, the clog is located farther down in the pipe and must be repaired by a plumber.

2. Water Leak

A water leak can cause low water pressure if the leak is significant enough. Sometimes water leaks of this magnitude happen if something damages your home’s pipes. Other times, water leaks because of corrosion or an incorrectly installed pipe. Identifying the problem is the first step. Signs of a water leak include:

  • Sound of constant running water in the walls
  • Wet areas and stains in the walls and floors of the house
  • Unexplained mold or mildew

Another way to tell if you have a water leak is to turn off all appliances and fixtures that use water in your house and then monitor the water meter outside. If the water meter continues to run when no one is using water in the house, this is a sign of a leak.

3. Faulty Water Pressure Regulator

A faulty water pressure regulator could also be the source of the trouble. Not all homes have water pressure regulators, but some do because their community’s municipal water source has high water pressure.

When water pressure regulators go bad, they can cause water pressure in the home to be either too low or too high. If the water pressure in the home is shifting back and forth between too high and too low, the cause may very well be a faulty water pressure regulator. Talk to a professional plumber to have a new one installed.

4. Clog in Your Water Supply Line

If the low water pressure affects more than one appliance, and you can’t find any leaks or problems with your water pressure regulator, the problem may be with your water supply line. You may have a clog or buildup of some kind in your piping that affects your home, or perhaps tree roots have grown into your pipes and blocked them.

If you suspect the problem is with your water supply line, contact a plumber right away. Don’t try to find and fix the problem on your own — you need a professional’s expertise.

If you’ve inspected your home’s plumbing and you have no idea what could be causing low water pressure, it’s time to work with a professional. A reputable plumber can identify the true source of your low water pressure and can also suggest possible solutions.
