The Best Toilets for Flushing Away All Your Heavy Waste

Clogged toilets and double flushing are a nuisance that no homeowner wants to deal with. When facing the challenge of eliminating large or excessive waste, you need a toilet with maximum flushing power to get the job done right.

We'll also recommend some of the top-rated models on the market for handling heavy loads with no clogs or obstructions.

Flush Power Basics

Key Factors That Determine Flush Strength

Not all toilets are created equal when it comes to flushing performance. Here are the main specifications that give a toilet exceptional waste removal strength:

• Flush valve size - A wider 3" or 4" valve diameter allows more water to flow into the bowl for a stronger flush.
• Bowl trapway width - A wider trapway leaves more room for waste to exit smoothly.
• Gravity-assisted vs. pressure-assisted flushing - Pressure-assisted uses air compression for added power.
• Flushing technology - Siphonic models create a stronger siphon effect than wash-down.

Features That Help Move Waste

Along with valve size and bowl design, extra features inside the bowl and tank can maximize flushing efficiency:

• Inner channels and jets help propel water into all areas.
• A spacious bowl shape prevents clogging and sticking.
• The tank/bowl connection should allow complete water flow.

Valve Types

Flapper Valves

Flapper flush valves, while very common, have some drawbacks:

• Prone to warping and leaking over time
• The flapper can obstruct water flow from tank to bowl

Flapperless/Canister Valves

Flapperless valves like the KOHLER AquaPiston are superior for flushing power:

• Unobstructed water flow for increased pressure
• Last longer than flapper models

Buying Considerations

Along with maximum flush power, also factor in:

• Bathroom size - Choose the right dimensions to fit.

• Budget - Prices range from $100 into the thousands.
• Toilet height/comfort - Standard is 15"-17" high.

FAQs

Typical causes of clogged toilets

Clogs most often result from large masses, excess toilet paper, or trying to flush inappropriate items. Tree roots invading underground lines can also obstruct waste flow.

DIY vs professional drain cleaning

For accessible clogs, a plunger or augur can clear simple obstructions. But severe or recurring clogs in tricky areas beyond the toilet trap require a professional's snaking tools and expertise.

Saving water without sacrificing flush power

Toilets with at least a 1.28 GPF rating provide a strong flush with less water. Dual flush models save water by using a lower volume for liquid waste.

Choosing electric vs gravity-fed models

Electric pressure-assisted units have added flushing power but tend to be noisier. Gravity models are quieter and more popular for residential use.

Troubleshooting a weak flush

A weak flush can stem from low water pressure, aged components like flappers, blockages, improper venting, or issues with the water inlet valve. Always check for leaks too.

Choosing a powerful flushing toilet is essential for effectively clearing waste and avoiding annoying clogs and double flushing. With the right valve size, bowl design, and flushing technology, models like the TOTO Drake II and Kohler Highline can tackle even the heaviest loads.

Consider your bathroom layout, water pressure, usage frequency and other factors along with maximum flush performance as you shop for the perfect clog-busting toilet.
