High water pressure in your home can be dangerous, but low water pressure can be just as dangerous. Sometimes reduced water pressure can be an easy fix, while in other cases it can be a permanent problem. For this reason, it is important that you contact your plumbing expert to solve the problem. Below are the six most common reasons for low water pressure and ways to fix the problem.

Low Water Pressure: What’s Causing It and How to Fix It

1. Clogged Pipes

One of the most common causes of low water pressure in many homes is clogged pipes. When water flows through your pipes, mineral debris, sediment, and other debris can accumulate on the pipe walls. Over time, debris can impede water flow and reduce water pressure.

The best way to prevent your pipes from clogging is to schedule regular line maintenance. During maintenance visits, your plumbing expert will flush the pipes and clean all your drains to keep the pipes clear.

2. Partially Closed Shutoff Valve

The other cause of water pressure problems is a partially closed shut-off valve. This valve is located near an appliance or the appliances it controls, such as a washing machine, dishwasher, toilet, or sink. If the shut-off valve is not fully open, it may restrict the flow of water to the plumbing fixture or appliance, resulting in reduced water pressure.

Not only can a partially closed shut-off valve reduce your water pressure, it can also lead to other problems, including leaky lines that can wreak havoc on your home. It can also damage the device or devices controlled by it. The best way to avoid all of these problems is to make sure all of the shut-off valves in your home are fully open.

3. Leaking Pipes

Leaking pipes can significantly reduce your water pressure by diverting water from a specific fixture to another part of your home. While large water leaks are easy to spot, small leaks can be hard to spot until they get bigger. To determine if a water leak is the cause of the reduced pressure, you must first determine if there is a water leak in your home.

To do this, turn off all appliances and plumbing in your home that use water. If your water meter works even when no water is being used, then there is a leak somewhere. A plumbing professional can help you check your lines for leaks and repair leaks to restore water pressure.

4. Partially Closed Meter Valve

A partially closed meter valve can reduce water pressure because it impedes the flow of water through your home’s plumbing system. The job of a water meter valve is to regulate the flow of water into your home. If the valve is not fully open, the flow of water through your home will be significantly reduced, causing the pressure in most of your plumbing fixtures to drop.

A partially closed valve can not only reduce water pressure but also cause other problems related to the water supply. The only way to fix this problem is to make sure the dispensing valve is fully open. If the water pressure does not improve after fully opening the valve, have your plumbing professional check your plumbing to determine the source of the problem.

5. Faulty Pressure Regulator

A pressure regulator controls and reduces the pressure of the water flowing through your home to prevent it from damaging your plumbing. However, if the water regulator is not working, it can lead to a drop in water pressure. Among other things, this results in slower water flow and longer waiting times for heated or lukewarm water to reach your taps. If you think the pressure regulator might be the reason for the reduced water pressure, you should call your local plumber to have the unit checked and replaced.

6. Municipal Water Issues

Sometimes water pressure problems have nothing to do with the plumbing in your home. These can be municipal water supply problems such as water treatment problems, major water disruptions or high water demands. If your neighbors are having the same problem, contact your provider to see if there is a problem and when they will fix it.

FAQs about the Most Common Causes of Low Water Pressure:

Q: What are the most common causes of low water pressure?

A: The most common causes of low water pressure are:

• Clogged pipes: Grease, sediment, and other debris can build up in pipes over time and restrict the flow of water.
• Low water pressure from the water main: If the water pressure from the water main is low, it can affect the water pressure in your home. This can happen during peak water usage times or if there is a problem with the water main.
• A faulty water pump: If your water pump is faulty, it may not be able to deliver enough water to your home. This can cause low water pressure throughout your home.
• A closed valve: A closed valve can restrict the flow of water to your home. Make sure that all of the valves in your plumbing system are open.
• A faulty faucet or showerhead: A faulty faucet or showerhead can also cause low water pressure. If you notice that the water flow from one of these fixtures is weak, it may be time to replace it.

Q: How can I tell if my water pressure is low?

A: There are a few ways to tell if your water pressure is low. One way is to check the water flow from your faucets and showerheads. If the water flow is weak or intermittent, you may have low water pressure. You can also check the water pressure gauge on your water meter. If the water pressure gauge is reading below 40 psi, you may have low water pressure.

Q: What can I do to fix low water pressure?

A: The best way to fix low water pressure depends on the cause of the problem. If the problem is clogged pipes, you may need to have the pipes cleaned or replaced. If the problem is low water pressure from the water main, you may need to contact your water utility company. If the problem is a faulty water pump, you may need to have the water pump repaired or replaced. If the problem is a closed valve, you may need to open the valve. If the problem is a faulty faucet or showerhead, you may need to replace the faucet or showerhead.

Q: When should I call a plumber for low water pressure?

A: If you have tried the above steps and you are still experiencing low water pressure, you may need to call a plumber. A plumber can diagnose the problem and recommend the best course of action to fix it.
