Low Water Pressure in Taps: Troubleshooting

If you have low water pressure in your home, it can be annoying and inconvenient. However, there are several common causes and potential solutions to help restore your water pressure to optimal levels.

Identifying the Problem

One of the first steps in troubleshooting low water pressure is determining if the issue affects your entire home or just a specific area or fixture. If the low pressure is localised, it could be due to a problem with the fixture, such as a clogged aerator or a faulty valve. On the other hand, if the low pressure is throughout your home, it's more likely to be a systemic issue.

Potential Causes and Solutions

Leaks

Water pressure can drop a lot if there are leaks in your plumbing. Check for any signs of leaks, such as dampness on walls or floors, and have them repaired by a professional plumber.

Clogged or Corroded Pipes

Pipes can get clogged with mineral deposits or rust over time, lowering water pressure and flow. If you suspect this is the cause, having a plumber inspect your pipes and recommend a solution, which may involve unclogging or replacing the affected pipes, is best.

Faulty Pressure Regulator

If your home is equipped with a pressure regulator, it may be malfunctioning and causing low water pressure. A plumber can test the regulator and adjust or replace it if necessary.

Shut-Off Valves

Ensure your plumbing system's main shut-off valve and other shut-off valves are fully open. With some closed, it can slow the water flow and lower the pressure.

Distance From the Water Source

If your home is far from the water source or at a higher elevation, it may naturally have lower water pressure. In such cases, installing a water pressure booster pump can help increase the pressure.

Seeking Professional Help

If you've tried troubleshooting the issue and are still experiencing low water pressure, it's best to contact a professional plumber for assistance. They can accurately diagnose the tap problem and provide the most effective solution to restore water pressure.

How can I identify if my low water pressure is due to a leak or a faulty valve?

To determine if a leak or a faulty valve causes your low water pressure, you can perform a simple test:

1. Turn off your home's tools and fixtures that use water.

2. Find your water meter and write down what it says.

3. Don't use any water for a few hours, or better yet, overnight.

4. Look at the water meter again. If the number has changed, your plumbing system leaks.

If the reading remains the same, the issue may be related to a faulty valve. Check if your plumbing system's main shut-off valve or any other valves are partially closed, as this can restrict water flow and reduce pressure.

What are the common signs of a plumbing leak that I should look out for?

Here are some common signs of a plumbing leak:

1. Dampness or moisture on walls, floors, or ceilings

2. Mold or mildew growth

3. Peeling paint or wallpaper

4. Cracks in tiles or grout

5. Unexpectedly high water bills

6. Running water sounds when you don’t use fixtures

A professional plumber should check your plumbing system to find and fix the leak if you notice any of these signs.

How can I measure my water flow rate at home accurately?

You'll need a bucket or container with a known volume and a stopwatch to measure your water flow rate at home. Follow these steps:

1. Place the bucket or container under the faucet or showerhead you want to measure.

2. Turn the water on to its maximum flow rate.

3. Use the stopwatch to measure how long it takes to fill the container to a specific volume (e.g., 1 gallon or 4 litres).

4. Calculate the flow rate by dividing the volume of the container by the time it took to fill it.

For example, if it takes 10 seconds to fill a 1-gallon container, your flow rate would be 6 gallons per minute (GPM).

What steps should I take if I suspect a problem with my internal stop tap?

If you suspect a problem with your internal stop tap, follow these steps:

1. Locate your internal stop tap, usually near where the main water supply enters your home.

2. Turn the tap clockwise to shut off the water supply.

3. Open a faucet or fixture in your home to release any remaining water pressure.

4. Contact a professional plumber to inspect the stop tap and determine whether it needs replacing or replacing.

Refrain from attempting to repair the stop tap, as specialised tools and expertise are required to ensure a proper and safe installation.

Are there any specific maintenance works that might temporarily reduce water pressure in my area

Yes, some maintenance works can temporarily reduce water pressure in your area:

1. Water central repairs or replacements

2. Fire hydrant testing or maintenance

3. Water meter installations or replacements

4. Valve exercising or replacement

5. Water treatment plant maintenance or upgrades

Suppose your local water authority is performing any of these maintenance works. In that case, they may need to temporarily reduce water pressure in your area to ensure the safety and efficiency of the work. In such cases, the reduced pressure should be restored once the job is completed.

Even after the maintenance work is done, if you still have this issue, you should call your local water authority or a professional plumber to investigate it further.
