Why Do I Have Low Water Pressure In My Home?

There is nothing better than stepping into a steaming hot shower after a long day’s work. 

But there’s nothing more disappointing than turning the tap full ball for a sad trickle to flow out of your shower head. 

Actually, no. It’s beyond sad. It’s depressing. 

Here’s your guide to diagnosing low water pressure issues Perth, what signs you should watch out for, how to measure it, and importantly, what you can do right now to fix it. 

Signs you’ve got low water pressure Perth

Low water pressure can manifest in several different ways. 

None of them are fun to deal with but should all be taken seriously. Here’s what to watch out for:

  • Low water pressure as soon as you turn on your tap or showerhead
  • A delay between turning on the tap and water actually flowing
  • Weak dribble coming from your shower head
  • Sinks and baths take an eternity to fill up

Causes of low water pressure Perth

Low water pressure can happen for a number of reasons. Annoyingly, it can be one small fitting that can cause a wealth of frustration. Alternatively, the problem could be unrelated to your property and could be due to a supply issue in your neighbourhood. 

Here are some common causes of low water pressure in Perth households and businesses:

1. Pipe Build Up

A build-up of debris or minerals in your water pipes can lower your home’s water pressure over time. It does this by reducing the diameter of the pipes, affecting the water flow and ultimately, your water pressure. 

Our team of licensed plumbers can use state-of-the-art drain cameras to assess the condition of your pipes and provide the best method to resolve any plumbing issues.

2. Main Shutoff Valves

Most homes have two major shutoff valves controlling the water supply to the home. The first is the water meter valve which is located next to the water meter on the city supply pipe. 

You do not normally use this valve as it is the property of the Water Corporation. However, if work has recently been completed, it may not be fully open. Check the handle is parallel to the water pipe, which indicates it is open correctly. 

The other valve is the property of your home. Make sure this is also fully open, by ensuring it is fully turned in a counterclockwise direction if it is a wheel-like handle or parallel to the pipe if a handle.

3. Too many taps on at once

Using more than one tap in the household simultaneously to access the water supply can result in low water flow through your pipes. Quickly walk around your home and ensure the other taps are tightly shut off before returning to check if the pressure has improved. 

4. Water Leaks  

If your water pressure problem has appeared suddenly, you may have a water leak in your plumbing system. Check for flooding or wet spots in and around your home. If there are no overt signs, you may have a concealed leak underground. We highly recommend you call your local Perth Plumbers immediately to locate and fix the leak. 

5. Stressed hot water system

Your water heater may be struggling to keep up with household demand. Alternatively, the water pressure valve located on the system may be faulty. It is worth calling the No Probs Plumbing team for advice and troubleshooting if this is the case. 

6. Faulty Pressure Reducing Valve

While these handy pressure regulator devices can ease the pressure on your pipes allowing them to last longer, they can also cause low pressure if faulty. If this is the cause it will affect the pressure of all fixtures in the home quite suddenly. Call in the professionals to organise a replacement. 

7. Water Maintenance Works 

The next step is to determine if there are any works in your area that may be contributing to your low water pressure. 

Check the Water Corporation’s Check Current Outages page to check if any works are being conducted in your area, or alternatively, give them a call on 13 13 75.

How to measure low water pressure

The Water Corporation provides 20 litres of water per minute to households across WA, but this can vary depending on the location of your water services on your property. 

Here is a simple test you can complete to check you are receiving the correct number of litres through the mains water system:

  1. Ensure all taps and water-using appliances are turned off. 
  2. Go to your water metre and note down the black and red numbers on your water meter. 
  3. Turn on your front garden tap for one minute and again note the reading on your meter. 
  4. Subtract the first meter reading from the second to determine the number of litres delivered during that minute.

If you are receiving more than 20 litres per minute, there may be an issue with your internal pipe-work. But if you are receiving less than 20 litres per minute, call the Water Corporation so they can further investigate your supply issue.
