Most Common Low Flow Toilet Problems

Low flow toilets use less water per flush compared to their full flow counterparts, and while this allows homeowners to significantly reduce their water consumption and save on water bills, it can sometimes lead to bothersome issues.

Double Flushing to Move Solid Waste Out

Since it uses only about half the amount of water most full-flush toilets do per flush, low flush toilets may have problems moving solid waste down the trapway. This can lead people to flush twice, using twice as much water which eventually defeats the purpose of having a low flow toilet. Perhaps one possible solution to this is to get dual-flush toilets that give users an option to use little water for flushing urine, or more for a forceful flush. A dual-flush toilet is one of several models under the low flow category.


Some low flow toilet models may be good for flushing down urine, but when it comes to moving solid waste out to the sewer, these may get clogged and result in a vexatious headache. With this in mind, it’s imperative to always read the manual and follow the care instructions properly to make sure your low flow toilet works at its very best. With the amount of water you can potentially save over time, the pros of getting one far outweigh the cons.

How to Unclog a Low Flow Toilet

No matter how carefully we adults use our toilets, small children will somehow manage to get rubber duckies and Lego blocks into the bowl. Seeing the water level rising instead of going down as you flush can cause you to panic, but before you do, remember you can always unclog using a plunger instead of calling a professional right away.

To unclog a toilet, wait for the water to go halfway down before you submerge your plunger. If it doesn’t, I’m afraid you will have to use a disposable plastic cup to scoop out excess water from the bowl before you can begin pumping. Trust me, you won’t like splashing this liquid all over the place as you plunge.

If you are using a flange plunger, carefully position the flange down the drain trap to ensure a tight seal. As soon as you achieve a nice seal, gently but firmly plunge down and up vertically whilst making sure not to break the seal. Repeat this process for 20 seconds and flush the toilet again.

Sometimes, the reason why toilets don’t flush well is inadequate water supply from tanks. This usually occurs in leaking tanks, which means that the flapper in the flush valve does not close properly. You can easily have these parts replaced by consulting an expert or doing it all by yourself.

Disadvantages of Low Flow Toilets to Be Aware of

We hope you enjoyed reading about the best low flush toilets on the market right now. However, there are some disadvantages to these types of toilets we want you to be aware of before making a purchase. 

First, low flow toilets don’t have the same strength as ‘normal’ toilets since they don’t contain as much water and can’t generate a powerful flush. As a result, this may require two or more flushes to get rid of your waste, thus leading to the same, if not more water waste than typical toilets. If your main purpose of purchasing a low flow toilet is to reduce water waste, this type of behavior isn’t exactly beneficial to your bill or benefiting the environment.

Also, as low flow toilets are typically kinder on the environment, they don’t produce a powerful flush, which can mean you’re more liable to blockages in your toilet and need more maintenance requests. Also, if your house is built on a slope or uneven surface, you might discover that the water cannot follow the direction of gravity, thus meaning you have to acquire several flushes. Newer houses tend to be more equipped and designed for low flow toilets, whereas older homes can struggle when it’s time to flush.

Fortunately, these disadvantages shouldn’t alter your thoughts on purchasing a low flow toilet, although they’re certainly considerations to bear in mind if you have a large household who will regularly use the toilet or lie in an old house with outdated plumbing facilities.

Other Things to Consider When Buying a Low Flow Toilet

Toilets are perhaps the busiest and most important utility in the house as far as sanitation is concerned and although you can get one at very affordable prices, it is still best to choose one that suits all your needs and preferences as replacing the one you’re not happy with can cause so much inconvenience.

Fortunately, there are several high-efficiency toilets in the market that allow consumers to save both water and money while enjoying the aesthetics and convenience they provide.

If you are about to buy one soon, these are the top most important things to consider:

Size and Space

No matter how excellent a toilet is if it doesn’t fit in your bathroom, you’ll never be able to use it. It is, therefore, important to determine the size of your bathroom before going out to purchase a toilet.

Toilet bowls come in different shapes and sizes. The standard elongated unit is between 18 to 19 inches long and fits in most full dimension bathrooms. The standard round-shaped toilet bowl, on the other hand, is between 16 to 17 inches long and is ideal for compact bathrooms.

Type of Flush

Low flow toilets use different flushing systems but are all designed to save on water. The toilets we see in most homes are siphoned toilets that use a siphonic action to flush, but this is also the type that’s most prone to clogging. Other households prefer wash-down toilets as these have wider trapways and are less prone to clogging. The only drawback with these types of toilets is that they require more frequent cleaning. Choosing between a siphonic toilet and a wash-down toilet is a lot like choosing between the plunger and the toilet brush. If you dislike plunging, then perhaps the wash-down toilet is best for you.


The most common type of toilets we see in homes today reveal the trapway, or that S-shaped route wastes take before completely going down the sewer. Usually, these are also two-piece toilets that include a bowl and a tank. There is no problem with “naked” toilets or those whose trapways show, but these are more difficult to clean than the skirted toilet or those with a concealed trapway design. Skirted toilets also offer better aesthetic value as they are nice to look at.

Tankless toilets are now getting more popular, and they are most suited for small or compact bathrooms. The tankless toilet we see in homes are not the same as the ones we see in commercial bathrooms though. Commercial bathrooms use flushometer toilets that use flushometer valve to flush down waste.
