Types of Flushing and Flush Ratings
The hallmark of a quality toilet is having enough flushing power for waste and toilet paper. A flush performance rating system classifies toilets from low to high based on their ability to remove solid waste and resist clogging. Look for these scores displayed on product packaging and on signs in your local store. Higher ratings mean better waste removal and clog resistance.
Here are some types of toilet flushing systems:
Single-Flush Toilets
- Standard single-flush toilets use the force of gravity to create a strong siphon during flushing
- These gravity-fed toilets are easy to repair
- The most common type of toilet
- Often cost less than other models
Dual-Flush Toilets
- Dual-flush toilets have separate flushes for solid and liquid waste
- Uses a larger diameter trapway design to resist clogging
- Needs less water to flush efficiently
- May require more frequent cleaning
Pressure-Assisted Toilets
- Pressure-assisted toilets have a special flushing mechanism within the tank that creates a siphon jet action
- Produces more forceful flushes than standard gravity-fed toilets
- Flushing action is boosted by air pressure and is less likely to clog
- Good choice for families because it uses less water per flush
Power-Assisted Toilets
- Also known as macerating toilets or up-flush toilets
- Best toilets to buy for new bathrooms in basements
- Pump permits flushing from below the sewer line
- Macerating pump liquifies waste during flush to reduce clogging and promote flow in lengthy waste lines
- Some models designed for boats or RV use
