A slow shower can be annoying, and you may be late for work!

Also, if water pressure is low, the bathtubs may take a long time to fill up, and the dishwasher may take forever to clean your utensils. All these can interfere with your daily routine, and you must find the root cause.

Common Water Pressure

We are here to help you understand the different causes behind low water pressure in the house. Once you have a clear idea, you can get a professional to fix the issue. Also, some of the problems can be sorted by you as well.

Read on to know more.

Common Causes of Low Water Pressure

1. Open Main Shutoff Valve

You should know that every house has two shutoff valves that control the water flowing in and out of the house. One of them is where the water supply line enters the house through the wall. In warm climate regions, it can be present outside the house as well.

Often during plumbing work, this valve is turned off partially to stop or adjust the water flow. If the plumbing team was not careful while working, they could have left this valve half-open. If you have recently had plumbing work done in the house, and the water pressure has gone down, this could be why.

Now, if you see a wheel-like handle of the valve, ensure it is turned entirely in an anticlockwise direction. If a lever handle is used, the lever should be parallel to the water pipe.

2. Corroded Steel Pipes

Have you noticed a slow drop in water pressure over the last few years? Then, that could be because of corroded steel pipes. Now, steel pipes usually get corroded over decades. The corrosion and the scale build-up ultimately block the entire pipe.

Corroded Steel Pipes Issue

But, if you have purchased an old home, the water pipes may already be corroded from the inside, and the water pressure may be low. In such cases, the only thing that you can do is to replace the pipes. You may also be able to opt for pipe relining, a less invasive form of pipe replacement.

However, you can replace the pipes with copper or plastic water pipes. These will solve the problem of low water pressure and ensure that you do not face this issue for decades.

3. Failing Pressure Regulator

Some houses have a pressure regulator attached to the pipes. This acts like a control valve and regulates the water pressure in the plumbing line to protect it from the increased flow of water. Not all houses have them, but if you do have one, it needs to be checked.

The water pressure can increase or fall significantly when the pressure regulator falters. The effect will be sudden, and you will notice a change in the water pressure in all the water pipes around the house.

Now, if the regulator falters, you can replace it with a regulator of the same brand and size. However, it is best to call professionals to handle this job. It would be best if you first shut down the main shutoff valve to change the pressure regulator.

Once that is done, you must turn on the valve and check the water pressure.

4. Open Water Metre Valve

A valve is placed right beside the water metre, known as the water metre valve. This is generally controlled by the city department and will primarily be handled by company personnel.

However, if you have had some repair work done in the house or the plumbing system has been changed, then the plumbing professionals may have fiddled with this valve. If the water pressure was perfect before the plumbing work, and you notice that it has gone down, the water metre valve may not be fully open.

You can find this valve on the outside wall of your house. It may also be in an underground box between your home and the street, basement, or garage. Find the location, and check if the valve handle is parallel to the water pipe. If not, the valve is not fully open, and the handle needs to be turned on.

Fixing Your Low Water Pressure Issues

If you want to check the water pressure, you can use a water pressure gauge. For this, the gauge must be attached to the outside hose spigot closest to the pressure regulator. If the water pressure is normal, then there is no further issue.

However, if it is still low, you will need to check all the valves and get professionals to check the water pipes for corrosion. Also, the regulator may be malfunctioning, which needs to be checked.

Even though you know about the common causes of water pressure, we recommend calling professionals if there is an emergency. They are trained to handle such jobs and can spot the issue immediately. Also, you will not have to spend time on it and can focus on your daily work.
