The best toilets for not clogging rely on wide trapways (usually 2.37 to 2.5 inches), massive flush valves, and pressurized or gravity-fed flushing technology. Top models include the American Standard Champion 4, TOTO Drake / Drake II, and American Standard Cadet 3.
The most clog-resistant toilets feature a wide trapway (at least 2.125 inches), a fully glazed interior to prevent waste from sticking, and a large flush valve. The American Standard Champion 4 and TOTO Drake are widely considered the industry benchmarks for preventing clogs.
Powerful flushing system: Look for toilets with powerful flushing mechanisms. Pressure-assisted toilets and dual-flush toilets are often known for their strong flushing performance, which helps prevent clogs. Larger trapway: The trapway is the channel that carries waste from the bowl to the drainpipe.
A toilet usually clogs easily because of excessive toilet paper use, flushing non-flushable items (like wipes), mineral scale buildup blocking the flushing ports, or a partial blockage trapped in the curved P-trap. It can also be caused by an older, low-flow toilet that lacks sufficient flushing power.
The strongest and most reliable flushing toilets are evaluated by their MAP (Maximum Performance) scores. The best-performing models fall into two categories: high-power gravity toilets, which are quiet and require less maintenance, and pressure-assisted toilets, which offer commercial-grade power but can be noisy.
Plumbers recommend sticking to three major brands: Toto, Kohler, and American Standard. They value these brands for their durable parts, reliable flushing mechanisms, and the ease of sourcing replacement components years down the line.
To instantly increase your toilet's flush pressure, maximize the water volume in the tank and clear out any blocked water jets. Most "weak" flushes are simply caused by the tank holding too little water or mineral buildup blocking the water flow.
Plumbers typically use a specialized plumbing tool called a toilet auger (or closet auger) to break up or retrieve stubborn clogs. If the blockage is easily cleared, they rely on a heavy-duty flanged or bellows-style plunger to force the obstruction through the pipe.
To prevent your toilet from clogging, flush as you go by pressing the handle halfway through a long session. Avoid putting excess toilet paper in the bowl at once, and stay hydrated and eat enough fiber so your stool is softer and easier to pass.
Dual-Flush Toilets
These eco-friendly toilets offer a choice of flushes, typically a half flush for liquid waste and a full flush for solid waste. Using the appropriate flush option reduces water consumption and the risk of clogs.
Dish soap has the ability to lubricate and break down the bonds of fats and grease. When poured into the toilet, dish soap helps lubricate the waste causing the clog, while also breaking down its structure, allowing it to easily flow down the drain.
While they share a similar base material, porcelain toilets are a premium, denser type of ceramic fired at higher temperatures. This makes porcelain highly durable, stain-resistant, and non-porous. Standard ceramic is more porous and budget-friendly, making porcelain the superior, long-lasting choice for bathrooms.
The most common toilet clog is excessive toilet paper. Using too much wadded paper at once—especially with low-flow toilets—overwhelms the system. Other frequent culprits include non-flushable items like "flushable" wipes, which do not break down in water.
Both Kohler and American Standard are high-quality, reliable brands, but the "better" option depends on whether you prioritize design and luxury (Kohler) or raw flushing power and value (American Standard). Kohler is better for aesthetic-focused, modern designs in primary bathrooms, while American Standard shines with efficient, clog-resistant, budget-friendly options.
I was wondering about the origin of using the terms "number one" and "number two" for going to the bathroom (for those unaware, number one is urinating, number two is defecating, at least in the US). I have used it several times myself without actually thinking about it and heard plenty of others use it as well.
Whether a 1.6 gallons per flush (GPF) toilet is better than 1.28 GPF depends on your priority. 1.28 GPF toilets are better for water conservation and lowering utility bills. 1.6 GPF toilets are historically better for heavy-use bathrooms where flushing power and clearing solids on the first try is the absolute priority.
People often put aluminum foil in the toilet tank as an internet cleaning or plumbing hack, usually claiming it softens water, prevents rust, displaces water to save on utility bills, or freshens the bowl.
Why are some poops so big they clog the toilet? Occasionally, a person may pass poops that are larger or longer than usual. Some causes of this may include constipation, IBS, and fecal incontinence.
To fix a toilet that constantly clogs, first address the immediate blockage, then troubleshoot the root cause. Clearing foreign objects in the drain, adjusting the water levels in the tank, and changing user habits will usually restore proper flushing power.
Green Gobbler Powder Plunger Toilet Clog Remover is here to help get rid of stubborn clogs and slow-moving drains to keep your toilet flowing properly. EASY TO USE: Grab a pre-measured Green Gobbler pouch and pour the entire contents into the toilet. Wait at least an hour or allow it to sit overnight, if possible.
A toilet that fills up and slowly drains almost always indicates a partial blockage in the trap or drain line, or clogged rim jets/siphon jets limiting water flow. You can usually resolve this yourself using common household tools without needing a plumber.
What NOT to Do When Unclogging a Toilet
If your toilet flushes but the waste stays behind, it is usually caused by a partial blockage, insufficient water in the tank, or blocked rim jets. This prevents the water from creating the proper siphon effect needed to pull waste down the drain.
Yes, some toilets flush significantly better than others. Performance varies widely depending on the internal engineering, valve size, and trapway design. Modern toilets use less water than older models, but advanced technology allows them to clear waste much more efficiently.
To make your toilet flush better, you should put a mix of dish soap and hot water in the bowl, or vinegar directly into the tank. These break down clogs and dissolve the mineral buildup (like calcium and lime) that restricts the water jets responsible for flushing power.
