Leaky taps. Toilets that never quite stop running. Burst pipes in the middle of the night. If you’ve dealt with any of these more than once, you’re not alone. In fact, one of the most common (and least known) causes of recurring plumbing issues is something hiding in plain sight: high water pressure.
At first, it might not seem like a problem. Strong pressure in the shower? Great. Fast-flowing kitchen tap? Even better. But here’s the thing—when the water pressure in your pipes is consistently too high, it puts your plumbing under strain, and over time, that strain causes fittings, joints, and seals to break down.
The Hidden Damage Of High Water Pressure
Water pressure in Australia is meant to sit between 350 and 500 kPa (kilopascals). Anything above that can slowly damage your plumbing system—especially the weak points like tap washers, toilet inlet valves, and older pipework.
You might not notice it straight away. In fact, high water pressure can go undetected for years. But during that time, it’s quietly forcing your plumbing to work harder than it should. Taps begin to drip. Pipes start to rattle. Seals wear out faster. Toilets begin to run constantly.
Eventually, one leak turns into two. Then three. Then a burst pipe.
What It Feels Like To Live With High Pressure
There are some subtle signs your water pressure might be higher than it should be. The most obvious is the way your water feels when you use it. Do your taps spray aggressively when you turn them on? Does your shower feel uncomfortably powerful, almost like a pressure washer? Does your washing machine make a knocking noise when it fills?
Over time, you may also notice a pattern of recurring issues—particularly with taps and toilets. You replace the washer, only for it to start leaking again within a few weeks. Or you’ve had more than one pipe repair in a short period, even though your plumbing isn’t especially old.
Why Pressure Testing Matters
You can’t guess water pressure by feel alone. That’s where pressure testing comes in. A professional plumber uses a gauge to measure the actual pressure inside your pipework and determine whether it’s within the safe, recommended range.
This one simple test can explain why you’ve been dealing with so many recurring issues. It takes minutes, requires no invasive work, and gives you a clear picture of what’s really going on inside your plumbing.
If high pressure is detected, your plumber will recommend a long-term fix—usually in the form of a Pressure Limiting Valve (PLV). These devices are fitted at the water entry point and ensure that water flows into your system at a consistent, safe pressure. Once installed, they silently protect your plumbing 24/7.
What Happens If You Ignore It
We often get called out for tap repairs, toilet leaks, and burst pipes—only to find the root cause is the same every time: unchecked high pressure. When left unaddressed, it can lead to:
- Constant drip repairs that never last
- Toilets that refill endlessly and waste water
- Hot water units that age faster than they should
- Increased stress on joints and pipework, eventually causing bursts
- Higher water bills and unnecessary energy use
The worst part? Most of this damage is preventable.
The Difference A Small Fix Can Make
Fitting a PLV or making minor pressure adjustments can significantly reduce your plumbing headaches. Instead of constantly reacting to leaks and bursts, you’re proactively preserving your system.
The result – longer-lasting fixtures, fewer emergency repairs, and a much more efficient household overall.
