10 Causes of Low Water Pressure in Your Home

13 December

Are the faucets in your home taking much longer to fill a bucket or bathtub? Or is a showerhead offering a weaker spray?

Either way, the culprit is a lower water pressure, which can arise for several reasons and manifest in many other ways, some you can blame in your internal plumbing issue. So, to get rid of this problem quickly, you’ll first need to understand its probable sources. That’s why we’ve prepared this simplified guide to help you out. Let’s start!

10 Causes of Low Water Pressure in Your Home

1. Issues With The Water Supplier

Before examining your plumbing system, know whether your neighbours are reporting similar issues. If so, then the low water pressure is probably not the result of any problem in your house. You can also reach out to the water supplier to figure this out and know whether they are trying to fix any issue in their supply system.

2. Partially-Open Main Shutoff Valve At Home

If your house is the only one in the block that’s witnessing this problem, it’s an indication that the issue lies in the house itself.

If the main shutoff valve is not fully open, the water supply can be adversely affected in many ways. That’s why it’s essential to locate the valve and check whether it’s fully open.

After you find the valve, figure out whether it has a wheel-shaped or lever-shaped handle. Accordingly, it would be best to open the valve by turning it fully counterclockwise or making it parallel to the pipeline.

3. Failing Pressure Regulator

A regulator adjusts the pressure at the source of your water supply to a level that’s ideal for the house pipes. However, remember that all plumbing systems aren’t equipped with this fixture.

A simple test can help determine whether the fixture is working correctly if you have it. Add a water pressure gauge to the external hose spigot, preferably closest to the regulator.

The gauge will instantly give you the water pressure reading when turning the water supply on. If that’s lower than that indicated by the regulator, the latter is indeed the source of the problem.

4. Clogged Pipes

Clogs can build up beneath the drains and deep within the pipelines. And the smallest of clogs can mess things up enough to result in reduced water pressure. 

Since such an issue can occur anywhere beneath the house, it’s among those situations when calling a plumber is the best way out. After all, trying to fix it on your own might make things worse.

5. Closed Water Meter Valve

The second valve that controls the water consumption in your home is the water meter valve. Since this belongs to the company, most residents won’t have to deal with it directly.

But if you had a plumbing job done recently and that’s when the issue was noticed, the chances are that the valve wasn’t opened fully after the work was finished. So, someone will have to open it to normalise the water pressure.

6. Changes In Water Regulations

The lower water pressure also might result from changes made in the water regulations applicable in your city. In that case, the water supplier doesn’t choose to comply with the changes. But installing a water-pressure boosting system at home can help solve this issue effectively.

7. Shared Pipelines

As the name suggests, shared pipelines supply water to multiple homes. This will cause the water pressure to fall when neighbours sharing the pipeline use the water for their needs. It implies the water supply is getting divided between more than one household.

However, if you can roughly estimate when the neighbours aren’t using their water, the water supply at your home should have the ideal pressure.

8. Corroded Pipes

Most pipes come with an expiration date, beyond which they might start corroding. And for those made from materials such as galvanised steel, the corrosion might start manifesting in just about 20 years. However, copper and brass pipes are relatively more long-lasting.

Note that older houses are more likely to have galvanised steel pipes, so you must track when they need replacement.

9. Faulty Fixtures

If you notice low water pressure in most of the plumbing fixtures in your house, the issue lies with either the pipes or the water supply system. But if a few fixtures have a low flow, you might want to check them out.

A limestone or dirt build-up might affect the aerators on faucets that reduce the volume of water released without changing the pressure. As such, you need to remove the aerators and find out if they need cleaning.

10. Leaking Pipes 

If the foundation or basement of your house is flooded, it’s obvious one or more of the pipes are leaking. However, a minor leak can also mess with the pressure by misdirecting the water supply. This implies even if all the other parts of the plumbing system work properly, you won’t get the normal flow.

Why Are You Experiencing Low Water Pressure?

Now that you’ve known all about the causes behind low water pressure in any home, you’ll surely be able to tackle such situations efficiently. Just be alert enough to notice any irregularity in the plumbing system, and if need be, don’t hesitate to call a licensed plumber to fix your residential plumbing issue. Most emergency plumbing situation just can’t be procrastinated. Reach out immediately to a qualified plumber for professional service on your water pressure issues and other plumbing problems. Better be safe than sorry, right?

On that note, it’s time to wrap up. See you soon and take care!
