What Is a Pressure Assist Toilet?

A pressure assist toilet uses a sealed pressure vessel inside the tank that stores compressed air. When you flush, that air forces water into the bowl with high velocity—creating a stronger, faster flush than a traditional gravity system. In short: instead of relying only on gravity, it uses stored air pressure to propel water into the trapway.

The technology results in a powerful flush that clears waste more effectively, reduces clogging, and often uses less water per flush than older toilets.

Why Choose a Pressure Assist Toilet in Canada?

Canadian homeowners and property managers choose pressure assist toilets for several region-specific reasons:

• Stronger flush for heavy use: Families, rental units, and commercial bathrooms benefit from fewer clogs and less double-flushing.
• Water efficiency: Modern pressure assist models often operate in the 1.0–1.6 gallons per flush (GPF) range—helpful in provinces with conservation programs.
• Cold climate advantages: Faster clearing reduces buildup and potential freezing risks in older drain lines during harsh winters.
• Long-term durability: The sealed pressure vessel typically requires less frequent attention than aging gravity parts.
• Value: Higher upfront cost but savings from fewer plumbing calls and lower water bills.

Gravity vs. Pressure Assist — Quick Comparison

Top Benefits of Pressure Assist Toilets

1. Fewer Clogs

Because of the high-velocity flush, waste clears the trapway more reliably—ideal for busy households or multi-tenant buildings.

2. Cleaner Bowl

The forceful water flow helps keep the bowl cleaner between manual scrubs, reducing staining and streaks.

3. Water Savings

Many pressure assist designs reach strong flushing performance while using as little as 1.0–1.28 GPF—helpful for water conservation and utility costs.

4. Low Maintenance

Sealed vessel designs have fewer everyday moving parts (no standard flapper chains), which can mean fewer repairs over time.

5. Great for Rental Properties & Offices

Owners and managers appreciate the low clog rates and durability, translating into fewer service calls and happier occupants.

Are Pressure Assist Toilets Loud?

Yes — pressure assist toilets are typically louder than gravity-flush models. The noise is the quick release of compressed air and fast-moving water. For many homeowners the trade-off—reliable flushes and fewer clogs—outweighs the increased sound. Modern designs have reduced noise compared to older models, but if quiet operation is a top priority, consider a high-performance gravity model or install the toilet in a bathroom where the sound is less disruptive.

Where to Buy Pressure Assist Toilets in Canada

Common retailers and channels:

• Home Depot Canada — wide selection and in-store pickup options.
• RONA — popular in many provinces for plumbing fixtures.
• Lowe’s Canada — national chain with online/in-store availability.
• Wayfair.ca — online options and customer reviews.
• Amazon.ca — convenient for shipping, but check returns/returns policies for big fixtures.
• Local plumbing supply stores — often have pro-grade models and expert advice.
• Direct from manufacturers — occasionally better pricing, warranty and support.

Installation Tips

• Hire a licensed plumber: For most homeowners it’s the safest route — installation must meet local building codes.
• Confirm rough-in size: Common sizes are 10", 12", and 14". Measure before ordering.
• Check water pressure: Recommended minimum ~25 PSI for optimal performance (verify your model's requirements).
• Consider comfort height: If accessibility or comfort is a priority, choose chair-height/comfort-height designs.
• Septic systems: If on septic, tell your plumber—low-flow and pressure assist can work well, but tank sizing matters.
• Noise placement: If sound is a concern, placing the toilet in a bathroom away from bedrooms reduces perceived noise.

Common Questions (FAQ)

Do pressure assist toilets need electricity?

No. They use compressed air and water pressure; no electrical hookup is required for flushing.

Can they be installed in older Canadian homes?

Yes—provided water pressure and rough-in size are compatible. Consult a plumber if you have very old plumbing or undersized water lines.

Are replacement parts easy to find in Canada?

Parts availability depends on brand. Major brands like American Standard, Kohler, and TOTO have good distribution; smaller brands may require ordering from specialty suppliers.

Do pressure assist toilets splash more?

No—modern bowl designs minimize splash despite the stronger flush. The water enters in a controlled way to clear the trapway efficiently.

Are they good for septic systems?

Yes—because they use less water per flush in many models, they can be septic-friendly. Always confirm with your septic contractor if you have an older or undersized system.
