Buying Guide
Key Considerations For Pressure Assisted Toilets
Understand how pressure-assisted systems differ from gravity-fed toilets. Pressure-assisted models use a sealed tank to build air pressure and drive a powerful flush that can clear waste with less water. Look for models that offer a WaterSense or CSA/cUPC certification to ensure efficiency and safety standards.
Water Efficiency And Flush Power
Evaluate GPF (gallons per flush) ratings and real-world performance. Models in this selection range from 1.1 GPF to 1.6 GPF, balancing flush strength with water savings. If you want maximum efficiency, prioritize 1.1–1.3 GPF options, while still ensuring reliable clearing power for your household needs.
Size, Height, And Bowl Shape
Choose between chair height (comfort height) and elongated bowls for user accessibility and space compatibility. Elongated bowls provide more seating area, while chair-height designs aid mobility. Consider rough-in distance (12 inches vs other measurements) to ensure a proper fit with existing plumbing.
Rough-In And Installation Details
Rough-in distance, outlet type (top, back, or floor), and the two-piece vs. one-piece configuration affect installation complexity. Ensure you have the appropriate supply lines and flange compatibility. Some models offer specific features like bedpan slots or flow-style tanks that impact cleaning and maintenance needs.
Maintenance, Cleanliness, And Certification
Look for surfaces that resist staining and ease of cleaning—EverClean surfaces are a plus. Certifications such as EPA WaterSense, CSA, and cUPC reflect compliance with efficiency and safety standards, which can influence long-term reliability and warranty coverage.
Brand, Availability, And Replacement Parts
Brand reputation and the availability of replacement parts matter for long-term maintenance. Some models are designed as replacements for specific systems, which can simplify upgrades and reduce installation costs. Verify compatibility with your existing rough-in, tank, and bowl configuration before purchase.
