There are many reasons why low water pressure can occur in a household. Sometimes, a minor inconvenience can end up becoming a real pain in the neck. Often your home’s water pressure issue may simply be a supply issue in your area and outside of your control. 

To give you an idea of what the problem might be, here are some common causes of low water pressure:

1. Clogged Pipes

When there’s an accumulation of debris or minerals in your pipes, it could end up affecting your home’s water pressure. This occurs because the diameter of the pipes reduces over time, limiting the water flow and pressure. Fortunately, licensed plumbing companies have the latest technology to help you resolve these issues and bring your water pressure back to normal.

2. Closed Shutoff Valves

Most households have two primary shutoff valves that control their water supply. The first is a water meter valve found next to the water meter, typically found at the front of the house, close to the street. In some cases low water pressure can be fixed by simply opening the water meter value, allowing a greater flow of water. 

The second valve is on your property. To ensure that it is fully open, turn it counterclockwise until it is entirely open. If it has a classic handle instead of a wheel-like fixture, make sure it is parallel to the pipe.

3. Many Taps Are Open at Once

Another common reason for low water pressure in a house is that many taps are open at once. Check all of your plumbing features to see if any taps are running, leaking, or dripping. Once you’ve done a full inventory, double-check the water pressure again.

4. Water Leakage

Water pressure problems can occur when there is a leak somewhere in your plumbing system. To verify that this is the issue, look for any flooding or wet spots near your plumbing fixtures and around your property. 

If you don’t spot any obvious signs of leaks, there could be a concealed leak underground or within the walls. If that is the case, you should contact professionals that offer 24-hour plumbing services in your area. They can quickly help you locate the problem.

5. Overused Water Heating System

Low water pressure can also be caused by a water heater struggling to meet the demands of a household. If this is the case, you can have an emergency plumber in Adelaide inspect your unit to troubleshoot and service it as necessary.

6. Ongoing Water Maintenance

Another factor contributing to low water pressure in your house is if some maintenance work is being done in your neighbourhood. You can perform a simple test to see if you are getting the right amount of water in your main system.

First, turn off all the taps and appliances that use water. Next, check your water metre and take note of the black and red numbers there. Turn on the taps in your front garden for a minute and recheck the reading on the metre. Subtract the first reading from the second to figure out how many litres of water are delivered within that minute. If you are getting more than 20 litres per minute, the internal pipework could be an issue. If you are getting less, you can contact your water provider for further information on the supply issue.


Many issues could be contributing to low water pressure in your home. There are many things to consider, from internal problems like leaks to external ones like maintenance work. If you are dealing with issues that you cannot solve on your own, it is best to consult an experienced emergency plumber in Adelaide.
