The Hidden Dangers of High Water Pressure in Your Home.

You turn on the shower and feel that strong blast of water — it’s satisfying, right?

But here’s the thing: when water pressure is too strong, it’s not just wasteful… it’s dangerous.

At UPR, we help homeowners across Toronto and the GTA who didn’t realize their plumbing was under stress — until a pipe burst, a valve failed, or a fixture cracked.

High water pressure is one of those silent threats. It doesn’t make noise. It doesn’t leak. But day after day, it puts your entire plumbing system under pressure — literally.

What’s Considered “Too High”?

Most homes should have water pressure between 40–60 psi (pounds per square inch). Once it climbs above 80 psi, you’re in the danger zone.

In some Toronto neighborhoods — especially where homes were upgraded or old pressure regulators were removed — we’ve measured systems pushing 100 psi or more.

That might make your shower feel great…
Until your pipes disagree.

The Real-World Damage High Pressure Causes

When pressure is too high, your plumbing starts aging faster:

• Washers in faucets wear out

• Valves start leaking

• Pipes develop tiny cracks

• Water heaters get strained

• And appliances like dishwashers or washing machines break down early

One UPR client in East York was replacing washing machines every 3 years — the culprit? A pressure regulator that hadn’t worked in a decade.

How to Know If It’s Happening in Your Home

Here are a few warning signs:

• Loud banging noises when you turn off taps (aka “water hammer”)

• Toilet fill valves hissing after flushing

• Leaks or dripping faucets that never fully stop

• Plumbing components wearing out faster than they should

• Showers that feel too powerful — or water blasts from hoses

And if your pipes are older — cast iron, copper, or even plastic — high pressure can weaken them beyond repair.

What UPR Does About It

We test your pressure. Simple as that.

If it’s high, we install or adjust a pressure-reducing valve (PRV), usually near your main water line. This keeps everything in that safe 40–60 psi range, protecting your pipes, fixtures, and appliances long-term.

And the best part? You still get great water flow — just without the silent strain.

Toronto Homeowner Tip:

Live in a two-story or high-elevation home? Pressure might fluctuate between floors — one of the first signs that your system needs regulating. We’ll test every level to make sure you’re safe.
