Discover the Most Common Causes of Low Water Pressure in Your Home
As plumbers we understand how extremely frustrating low water pressure can be for a homeowner, especially when you’re trying to wash dishes or take a shower. If you’re experiencing this issue, there could be a variety of reasons for it. In this blog, we’ll explore some of the most common causes of low water pressure and possible solutions.
Buildup of Debris in Pipes
One of the most common reasons for low water pressure is debris buildup in your pipes. Dirt, sand, solidified oil and grease, food particles, and foreign objects can all cause blockages in your plumbing system. Mineral buildup can also clog your pipes over time, reducing the space for water to flow through.
Over time, pipes can corrode, resulting in oxidation that restricts the flow of water. This is especially common in older galvanized steel pipes. Corroded pipes may develop holes that can eventually cause them to fail completely.
Water Meter Valve Problems
If you’ve recently had work done on your plumbing system and are experiencing low water pressure, it could be due to a closed or partially open water meter valve. This valve is usually owned by your local water supplier and controls the flow of water into your home.
Partially Closed Water Shutoff Valve
The water shutoff valve is another possible culprit for low water pressure. If it’s only partially open, you won’t have full water pressure. To resolve the issue, you can try reopening the valve. If it’s a lever-type valve, move the handle until it’s in line with the water pipe. If it’s a wheel-type valve, turn the wheel counterclockwise until it’s tight, then turn it a quarter turn clockwise to prevent it from getting stuck or springing a leak.
Faulty Pressure Regulator
A pressure regulator is designed to maintain a constant water pressure in plumbing systems that have one installed. If you have low water pressure, try adjusting the regulator. If it’s faulty, it may need to be fixed or replaced by a licensed plumber.
If you suspect or spot a leak in your plumbing system, it could be causing low water pressure. Water may be diverted or flowing out of the pipe, preventing it from reaching where it’s supposed to.
Water Supplier Problems
If your water supplier is experiencing water pressure problems, you may also have low water pressure at home. If your neighbors are experiencing the same issue, contact your water supply company to inquire about any ongoing issues and expected fix times.
