Why is My Home's Water Pressure So Low?

There is nothing more annoying than looking forward to a nice hot shower only to discover that your water pressure is pathetically low- you can’t even wash the conditioner out of your hair properly! Low water pressure doesn’t just affect your shower, it can impact every aspect of your plumbing system from toilets to taps.

But why is the water pressure in your home suddenly so low?

Common Causes of Low Water Pressure

Understanding the root cause of your low water pressure is the first step in figuring out an effective solution. Our team of expert plumbers;

High Water Demand

We’ve all been there. You’re in the shower and it’s a perfect temperature when all of a sudden someone turns a tap on downstairs and your shower is freezing cold. When multiple water outlets are used at the same time, the pressure can drop. Water pressure can also drop during peak times like mornings and evenings.

Clogged Pipes

Without regular maintenance, your home’s plumbing system can become clogged due to the accumulation of mineral deposits, rust, organic matter or foreign objects. These blockages stop water from flowing freely.

Corroded Plumbing

Every plumbing system, especially those in older homes are vulnerable to corrosion. As your pipes break down and corrode, materials from inside the pipe restrict waterflow. This process can lead to a significant drop in your water pressure over time.

Problems with Your Water Supplier

Has your water pressure dropped without warning? Local governments and councils may be performing routine maintenance or repairs on the mains water supply in your area. To check if your suburb is having problems with its water supply, check out Sydney Water’s Outage map here.

What Should You Do When Your Water Pressure is Low?

Check the Main Water Valve

Your home’s main water valve controls the flow of water into your home. This valve is located near your water metre and should be fully open to allow optimal water flow. However, it can sometimes get left partially closed after routine maintenance or accidentally moved.

Look For Leaks

One of the most obvious and easy ways to check on your low water pressure is to inspect your plumbing system for leaks. Make sure to check your showers, taps, toilets and appliances such as dishwashers and washing machines.

Test During Low Demand Times

Is your low water pressure only noticeable at peak times? Try testing it when your house is empty or outside of peak times.

Talk to Your Neighbours

You never know, this problem might not be isolated. Double check with your neighbours to figure out if they are experiencing problems with their water pressure.
