If your house is experiencing low water pressure there are a few common causes such as a leak, a burst pipe, and water works in the area. Follow our top troubleshooting tips for diagnosing low water pressure in your home.

Check For Simultaneous Use

The simplest explanation to a sudden drop in water pressure is that water is being used simultaneously in another area of the house. So the first thing that you should do is walk through your home and check if anyone is showering, using the dishwasher, doing a load of laundry, or anything else that could be affecting water flow throughout the house.


Once you’ve ruled out simultaneous water usage as the cause of low water pressure in your home, the next step is to assess the scope of the problem. For example, is it only hot water that is affected or both hot and cold water? If low water pressure is only as problem for hot water outlets there is likely a problem with your hot water system. To fix this you will need to contact a professional.

If the low water pressure affects both hot and cold outlets, check the water pressure in other areas of the house. If the entire house has water pressure issues there is more than likely a problem with the water lines that may not have anything to do with your property. If this is the case, wait an hour or two and then test the water pressure again. If the problem persists, contact your local plumber.

Check Water Quality

A simple check you can do when water pressure is low is filling a clear glass with water. If the water is discoloured or there is debris it could be an indication that there is corrosion or a clog in your pipe.

If you suspect that there is corrosion in your pipe consult a professional plumber immediately as avoiding the problem could lead to a burst pipe and thousands of dollars of property damage.

Check For Leaks

Leaks can reduce the amount of water that reaches your taps causing low water pressure. Check inside cabinets and on the walls and floor near the affected outlets for possible leaks. If your home has multiple storeys, check the walls and ceiling on the lowest level for water damage that could indicate a leak.

If you have located or suspect that there is a leak, book an appointment with your local plumber to prevent further water damage.

Check Water Supply Valve Is Fully Open

Once you have ruled out rusted and leaking pipes, check that the water supply valve is fully open as this controls all water flow to your house. This is typically located in the same place as your water meter, usually near the front of the property. Gently turn the valve in the direction of the arrow until you feel resistance, without forcing it. If the valve doesn’t move it is already open.

Check For Works In Your Area

Another possible explanation of a sudden drop in water pressure is that there are works happening in your area. Your water company should give you notice of any upcoming works in your area, however, there may be unplanned work happening such as repairs on a burst water main.

If your home’s water pressure is affected for more than an hour or two, contact your water company to see if there are any works happening in your area. Or if you’re unsure whether it’s a problem with your private plumbing or the water mains, check to see whether or not your neighbours have been affected.
