Why Do I Have Low Water Pressure?

Wednesday, December 14th, 2022

Have you noticed less water coming from your faucets when you turn them on? This decrease in water from your plumbing system can mean you have low water pressure. This issue may mean you spend more time at the sink or bath getting the water that you need, which may frustrate you.

Sometimes, changes in water pressure occur due to issues with the water supplier. You can confer with your neighbors to see if they experience the same problems that you do to confirm this.

If this is not the case, there are several other reasons you might experience low water pressure on your property. Read on to learn about three of these causes and how to resolve them.

Common Reasons for Low Water Pressure

Valve Blockages

If you have ever had a clog in your drain before, you know that this type of blockage can disrupt the flow of water through your plumbing system. Your system contains valves that can open and shut to control the flow of water in and out of your building.

If the main shutoff valve or the water meter valve is not open all the way, this creates enough of a blockage to impact your water pressure. Check the levers that control these valves to make sure they are in the open position.

Failing Pressure Regulator

Not all properties feature a pressure regulator. But if you do have one, and it is no longer working, this could force your system to have a lower water pressure. This device monitors the pressure passing through your water supply line and ensures it remains at a safe level.

If it does not take this measurement properly, it may let through a low pressure. You can test the pressure yourself, but it might be a good idea to consult with a plumber about this concern. They can replace the regulator if needed.

Pipe Damage

Your pipes carry water to and from your property. So if these fixtures sustain damage, you might notice a drop in the water pressure in your building. Like valve blockages, you might see low water pressure when the pipes form clogs. You should talk to your plumber about this possibility and how to remove the clog in question.

Pipes can begin to corrode after several decades of use. You might not be able to see this type of damage as it could exist in the pipes’ interior. Your plumber can use video technology to inspect the pipes for signs of this damage.

A leak in your plumbing system means that the water starts to redirect through this damaged part of the pipe, taking away from the water meant to flow where intended. You might spot leaks if you see accumulated water on your property. But you should contact a plumber to properly fix this issue. Temporary patchwork will not last long and could lead to structural damage to your property.
