Low water pressure in your home is more than just an inconvenience — it can signal deeper issues within your plumbing system. Whether it’s a slow shower, a trickling faucet, or trouble running appliances efficiently, decreased water pressure can affect your everyday routine.
At Atlas Plumbing, we help homeowners identify and resolve the root causes of low water pressure before they lead to bigger plumbing problems. Below, we break down the most common reasons your water pressure may be lower than it should be.
1. Mineral Buildup in Pipes
One of the most frequent culprits is hard water. Over time, minerals like calcium and magnesium can accumulate inside your pipes, reducing the interior diameter and slowing down water flow. If you live in an area with hard water and don’t have a water softener, this could be a leading cause.
2. Hidden Leaks in the Plumbing System
A leak doesn’t have to be dramatic to make an impact. Even a small, slow leak behind a wall or under your home can reduce water pressure. Leaking pipes divert water away from the fixture you’re using and can lead to water damage and higher utility bills if left unaddressed.
3. Corroded or Aging Pipes
Older homes with galvanized steel pipes may experience corrosion inside the plumbing system. As pipes deteriorate from the inside out, the buildup restricts water flow. If your home is over 40 years old and you’re experiencing pressure issues, it may be time to consider repiping.
4. Partially Closed Shut-Off Valves
If your water pressure recently dropped after plumbing work or a major appliance installation, check your main shut-off valve or the water meter valve. If either is partially closed, it can limit how much water is flowing into your home. Ensuring both are fully open is a quick fix many homeowners overlook.
5. Issues With Your Pressure Regulator
Some homes have a pressure regulator (also called a pressure-reducing valve) that controls water pressure from the main line. If the regulator fails or is set too low, it can cause inconsistent or persistently low pressure. Replacing or adjusting the regulator may resolve the problem.
6. Problems With the Municipal Water Supply
Sometimes, the problem isn’t in your home at all. Local water main issues or municipal maintenance can temporarily affect water pressure. You can contact your water provider to see if there are any reported problems in your area.
Don’t Let Low Pressure Lead to Bigger Problems
While low water pressure can be frustrating, it’s often a symptom of something deeper. Ignoring it could result in costly damage or repairs later on. Whether it's a clogged pipe, a hidden leak, or an issue with your water pressure regulator, our team is here to help.
