A pressure-assisted toilet is a type of high-efficiency toilet that uses pressurized air to generate a more powerful flush. Unlike gravity-based toilets that rely solely on the force of gravity to siphon water down the drain, pressure-assisted toilets use compressed air stored in a plastic tank inside the vitreous china tank to compress the water and force it down the toilet at high pressure. This results in a faster, more effective flush that cleans the bowl more thoroughly with less water.

Pressure-assisted toilets have become popular in recent years due to their increased flush power and efficiency. They can be beneficial in certain situations, but also have some drawbacks to consider before installing. Understanding how they work and their key features allows homeowners to make an informed decision about whether a pressure-assisted toilet is right for their needs.

How Does a Pressure-Assisted Toilet Work?

The key difference between a pressure-assisted toilet and a gravity toilet lies in the tank. Instead of containing just water as a gravity toilet does, the tank of a pressure-assisted toilet has a second inner tank that holds compressed air. Here are the steps in a pressure-assisted flush:

• When the flush lever or button is pressed, the flush valve at the bottom of the tank opens.
• The compressed air in the inner tank pushes down on the water in the outer tank with up to 25 PSI of pressure.
• This highly pressurized water creates an extremely powerful siphon effect as it rushes into the bowl.
• The forceful surge of water flows through the trapway and down the drain pipe, cleaning the bowl thoroughly.
• More water flows from the tank to the bowl to replenish the water level in the bowl.
• The flush valve closes and fresh water refills the tanks in preparation for the next flush.

The pressurized air tank is typically made of a tough plastic resin material that can withstand years of high-pressure flushing. It re-pressurizes after each flush when fresh water flows into the outer tank. This compressed air is what gives pressure-assisted toilets their boosted flush power.

Key Features and Benefits of Pressure-Assisted Toilets

Pressure-assisted toilets offer several notable features and advantages:

Powerful Flush

The pressurized water creates a high-velocity swirl effect inside the bowl that scrubs every surface thoroughly. This generates a strong siphon that can effectively clear waste with just 1.0-1.6 gallons per flush (GPF). Gravity toilets often require 1.6 GPF or more to provide adequate flush performance.

Enhanced Flushing of Solid Waste

The forceful flush provides superior clearance of solid wastes compared to gravity models. Pressure-assisted toilets are capable of handling a larger mass of waste and transporting it over longer drain lines.

Excellent Bowl Cleaning

Due to the scrubbing action of the pressurized water, the bowl stays cleaner longer between flushes. The smooth vitreous china bowl surface helps prevent streaks and stains.

Quieter Operation

With no flapper or chain, a pressure-assisted toilet flushes very quietly. The pressurized surge of water makes less noise than the turbulence created by gravity models.

Water Efficiency

Pressure-assisted toilets consume 1.0-1.6 GPF, qualifying them as EPA WaterSense certified high-efficiency toilets. Gravity toilets use 1.6 GPF or more. The pressurized flush allows pressure-assisted models to use 20-25% less water while still providing equal or greater flush power.

Lower Risk of Clogs

Due to the increased siphon effect that thoroughly empties the bowl, there is less risk of clogs compared to gravity toilets. The pressurized water can transport waste farther through drain lines.

Durable and Reliable

With fewer moving parts, pressure-assisted toilets are built to last for years of dependable flushing. The inner tank requires little maintenance besides occasional inspection.

Considerations Before Choosing a Pressure-Assisted Toilet

Despite their many benefits, there are some important factors to weigh when deciding between a pressure-assisted or gravity toilet:

Noise

Although quieter than gravity models, pressure-assisted toilets still produce more noise than gravity toilets due to the sound of the compressed air rushing through the tank. This can be an issue in smaller bathrooms.

Forceful Flush

The high-pressure surge of water entering the bowl can be surprisingly loud and splashy. The pressurized stream hitting the standing water causes more splashing than a gravity toilet.

Toilet Shaking

The pressure-assisted flush can cause the toilet to vibrate or shake slightly when flushing. If not properly tightened to the floor, this can cause the toilet to move over time.

Price

Pressure-assisted toilets typically cost more than gravity toilets. The additional inner tank and sealing mechanisms increase the manufacturing costs. Expect to pay $200-500 or more.

Repair Difficulty

Due to their more complex tank design, repairs usually require replacing the entire inner tank assembly. This can be more difficult and expensive than repairing a gravity toilet.

Accessory Compatibility

Some toilet accessories like slow-close seats may not be compatible with the more powerful flush. Homeowners should check for pressure-assisted toilet compatibility before purchasing accessories.

Lower Flushing Flexibility

Unlike gravity toilets that allow a light flush or full flush, pressure-assisted models only have one high-pressure setting. This can waste more water.

Risk of Tank Rupture

If the inner tank develops a leak or crack, the compressed air can cause the tank to rupture, requiring immediate replacement. Proper installation helps minimize this risk.

Choosing the Best Pressure-Assisted Toilet

Homeowners who decide a pressure-assisted toilet can meet their needs should compare the following features when selecting a model:

• Bowl Shape: Elongated bowls provide greater comfort versus round bowl designs.
• Comfort Height: Higher seating around 16-17 inches off the floor makes sitting down and standing up easier.
• Water Usage: Look for EPA WaterSense models that use 1.28 GPF or less.
• Flushing System: A fully glazed trapway helps waste slide through smoothly.
• Manufacturer Warranty: Lifetime or limited lifetime warranties provide peace of mind.
• Reviews: Check reviews for flush performance, reliability, and noise levels.

Top-rated pressure-assisted toilet brands include American Standard, Kohler, Toto, and Niagara. Prices range from around $250 up to $500+ for higher-end models. Carefully inspecting the inner tank and fittings during installation can help minimize potential problems down the road.

FAQs About Pressure-Assisted Toilets

What is a pressure-assisted toilet?

A pressure-assisted toilet uses compressed air in an inner tank to pressurize the water during flushing. This creates a highly pressurized siphon effect that generates a more powerful and effective flush compared to a gravity toilet.

How does the pressure mechanism work in a pressure-assisted toilet?

An inner plastic tank inside the outer vitreous china tank contains compressed air (generated upon refilling after a flush). When the flush valve opens, this pressurized air pushes down on the water in the outer tank, forcing it into the bowl at 25 PSI. This creates a surge effect that cleans the bowl thoroughly.

Why is the flush so loud on a pressure-assisted toilet?

The combination of compressed air rushing out of the tank and pressurized water surge creates more noise than a gravity flush. The forceful water stream hitting the bowl adds to the splashing sounds.

Do pressure-assisted toilets clog easily?

No, a pressure-assisted toilet is less prone to clogs than gravity models. The pressurized siphon effect creates a stronger pull that can move waste further through the drain pipes with each flush.

Do pressure-assisted toilets use less water?

Yes, pressure-assisted toilets consume 20-25% less water per flush compared to gravity toilets (1.0 – 1.6 gallons vs. 1.6 gallons or more). The pressurized surge allows them to fully clean the bowl with less water.

What are the advantages of a pressure-assisted toilet?

Benefits include increased flush power, superior bowl cleaning, excellent waste removal, quieter operation, water efficiency, smoother flushing, and lower risk of clogs.
