PRV Valve Replacement & Maintenance

Keep Your Water Pressure Balanced, Safe, and Code-Compliant

A faulty or aging Pressure Reducing Valve (PRV) can cause low water flow, burst pipes, and even damage your appliances. Whether you’re dealing with high-pressure surges or sudden drops in flow, Plumbing On Site offers full-service PRV inspection, maintenance, and replacement across the GTA.

Our licensed technicians test your pressure levels, adjust or repair your valve, and if needed — install a new unit that meets building code and lasts for years to come.

Common PRV Issues

We Fix

Pressure problems don’t always start with a bang — but they can end in one. Whether it’s a slow drop in water flow or a sudden burst from too much pressure, Plumbing On Site is here to help you catch and correct PRV issues before they cause serious damage.

Inconsistent Water Pressure?

Fluctuations in pressure from fixture to fixture?
We diagnose and repair malfunctioning PRV valves that cause surges or drops — restoring stable, even flow throughout your plumbing system.

Old or Failing Valve?

Is your existing valve corroded or leaking?
We replace outdated or faulty PRV units with code-compliant, long-lasting models — calibrated and installed by licensed pros.

Pressure Too High?

Appliances rattling or pipes knocking?
Excessive water pressure can ruin fixtures and lead to bursts. We test your system and install the right valve to keep pressure safe and steady.

Keep It Running Right

Don’t wait for failure to strike.
Our scheduled PRV maintenance includes pressure checks, cleaning, and valve testing to avoid unexpected breakdowns or water damage.

What Kind of PRV Issue

Are You Facing?

Whether you’re managing a home, condo, or commercial property, Plumbing On Site is your go-to partner for PRV valve solutions across the GTA.

From odd pressure drops to full-blown pipe bursts, a malfunctioning PRV can cause headaches you didn’t see coming. That’s why we’ve broken down the most common scenarios — so you can understand the problem and how our licensed plumbers fix it quickly, safely, and with long-term results.

Tap through the sections above to learn how we restore balance to your water system — one pressure valve at a time.

Leaking PRV Valve

Over time, valve seals wear out and begin to leak. We replace internal components or the full unit to restore safe, sealed function.

Fluctuating Water Pressure

If your pressure constantly rises and falls, your PRV may be malfunctioning or misaligned. We fine-tune or repair it for consistent flow.

Unusual Noises

Whistling or banging in the pipes? That’s often a sign of internal PRV issues — we inspect and correct pressure imbalances quickly.

Outdated or Corroded Valves

Old PRVs lose effectiveness and may no longer meet local plumbing codes. We install modern, efficient models built to last.

Code-Compliant Installations

We ensure your replacement valve is properly sized and located, and we provide full pressure testing before wrapping up the job.

High-Rise or Multi-Unit Solutions

For condos or commercial buildings, we handle centralized valve upgrades and coordinate pressure balancing across multiple zones.

Low Water Flow at Fixtures

Showers or taps running weak? We use calibrated gauges to test your incoming pressure and adjust the PRV to ideal settings.

Preventative Pressure Regulation

Even if you’re not having problems yet, regulating high pressure early can save pipes and appliances from long-term wear.

Thermal Expansion Issues

High pressure from hot water tanks can cause strain. We ensure your PRV works in tandem with expansion tanks for system stability.

Avoid Sudden Failures

Just like other critical components, PRVs benefit from periodic service. We clean, test, and adjust valves on a regular schedule.

Commercial & Property Management

We offer maintenance plans for buildings with multiple PRVs — ensuring pressure control and code compliance without the hassle.

System Monitoring & Recordkeeping

Our team tracks maintenance and replacement history, so you always know when it’s time for your next service.
