Pressure Reducing Valve (PRV) Installation in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
If incoming city pressure is too high, fixtures wear out faster, fittings leak more often, and water heaters and dishwashers fail prematurely. A pressure reducing valve (PRV) drops the pressure to a safe range — usually 50 to 60 psi. Tornado Plumbing & Drains installs and replaces PRVs across Toronto and the GTA where pressure tests show the supply is over the recommended range.

When this page makes sense
A good place to start for low pressure, underground leaks, shut-off problems, or supply-side upgrades tied to renovations and older services.
Most common signs
- Whole-home low pressure, visible underground leaking, or unreliable shut-offs usually point to supply-side work.
- Older lead or galvanized services often need long-term planning, not repeated spot fixes.
- If pressure changes after nearby construction or renovation, the diagnosis needs a broader system view.
What the visit usually includes
- 1. Pressure test: Confirm incoming pressure with a gauge.
- 2. Locate install point: Usually right after the main shutoff.
- 3. Install PRV: Cut into the line, install valve and required gauge.
What changes price and scope
- Repair versus replacement scope, access route, and excavation needs.
- Pipe material, shut-off condition, and whether permits or coordination with utilities are required.
- Whether the job includes pressure regulation, service upgrade, or restoration work after access is opened.
How a professional visit usually unfolds
1. Pressure test
Confirm incoming pressure with a gauge. PRV only makes sense when pressure is actually high.
2. Locate install point
Usually right after the main shutoff. Protects the entire home.
3. Install PRV
Cut into the line, install valve and required gauge. Permanent installation.
4. Set target pressure
Adjust output to 50 to 60 psi. Right pressure for fixtures.
5. Add expansion tank if needed
When closed system, an expansion tank prevents thermal pressure spikes. Required by code in many cases.

The written terms are provided with every quote. If our work fails within 25 years of the install date, we come back and make it right.
Signs of high water pressure:
- Banging or hammering pipes when valves close.
- Repeat fixture leaks (faucet cartridges, toilet fill valves).
- Toilet fill valve hisses or runs constantly.
- Water heater T&P relief valve drips.
- Appliances (dishwasher, washing machine) failing prematurely.
- Spitting at faucets when first opened.
PRV installation cost
Pricing depends on whether the work is new install or replacement, whether an expansion tank is required, and how accessible the supply line is at the install point. Replacement of an existing PRV is the lowest range. New installation with expansion tank is higher.
What to share when you call
- Pressure symptoms.
- Whether a PRV already exists.
- Approximate age of the existing PRV if there is one.
- Photos of the main shutoff area.
- Any expansion tank already installed.
- Recent water heater issues.
Toronto context
Toronto street pressure can swing 60-100 psi depending on neighborhood and elevation. A PRV protects the home's plumbing from the high end — preventing premature failure on dishwasher hoses, toilet fill valves, and aged solder joints. We size the PRV to the home's flow demand, not just the line size.
When this is not enough
A new PRV protects the plumbing going forward. It does not undo damage from years of high pressure. If high pressure has already failed valves, weakened supply lines, or cracked fixtures, the right next step is a repipe or supply-line repair scope alongside the PRV install — not just the valve.
What to confirm before approving PRV work
- Pressure should be tested before recommending a PRV.
- Expansion tank requirements should be addressed for closed systems.
- Output pressure should be set to the right range and verified at fixtures.
Useful info on the call: pressure symptoms, existing PRV status, and water heater behaviour.
Frequently asked questions
What is the right water pressure for a home?
Generally 50 to 60 psi. Above 80 psi is too high for most fixtures and appliances. Below 40 psi feels weak.
How long do PRVs last?
Typical residential PRVs last 10 to 15 years. Failed PRVs often cause sudden high pressure, leaks at fixtures, and water heater issues.
Do I need an expansion tank with a PRV?
Often yes. A PRV creates a closed system, which means thermal expansion from a water heater has nowhere to go. An expansion tank handles that pressure spike. Code requires it in many situations.
Will a PRV fix low pressure?
No — a PRV only reduces pressure. Low pressure usually points to the buried service line, the city tap, or interior pipe restriction. Different fix.
