How to Choose the Best Flushing Toilet
No one wants to purchase a terrible flush toilet. However, sometimes we find ourselves with a flawed model simply because we did not have enough information to help us make the right choice.
In addition to the above reviews of the top 10 flush toilets, we now provide you with additional information to guide you in making an informed choice. First, let’s discuss the types of flush toilets available in the market.
We can recognize three types of flush toilets. They all differ in design and flushing mechanism. You need this information to help you make the right decision.
Traditional Single Flush Toilets
Several years ago just about every home had a flush toilet. These older oval offices used pressure siphoning mechanism to flush waste from the toilet bowl. The moment you activate the flush mechanism, all the water in the tank would flow through siphoning pipe to eliminate the waste.
The problem with such traditional models was the tendency of the siphoning system to clog. They also tend to be noisier than modern types. While some brands have managed to create more sophisticated siphoning systems that have lower tendency to clog, newer models are much better.
Low-Flow Flush Toilets
The US federal government was not comfortable with the water wastage associated with the single flush toilets. In 1992, the Federal Energy Policy introduced an act that required all new toilets installed in the US to use water not exceeding 3.5 gallons per flush. This led to the introduction of the so-called low-flow toilet models that complied with the new act.
Initial productions also used a siphoning system that was made more efficient. They could use 4.8 liters or less per flush. However, their efficacy in performance was always dogged by the requirement to flush twice to eliminate waste. Many toilets today are low flush models that consume even lesser water per flush but do not require double flushing.
Dual Flush Toilets
There are new generation flush toilets that were invented in Australia. They usually use gravity assisted flushing system. Activation of a flushing system opens large a trap door (referred to as trapway) through which the waste materials from the toilet bowl flow out. The mere size of the trapway minimizes any chances of clogging.
The designation dual means it has two (dual) setting mechanisms that drive the operation. You might see a button and a lever or two buttons in a few cases. The lever operates low volume flush while the button operates high volume flush.
The low volume flush gets rid of liquid waste while the high volume flush expels solid waste. Thus you will conserve water when flushing liquid waste. Single flush models use a high volume of water for all types of waste.
Benefits of the Dual Flush Toilets
There are many benefits of dual flush toilets over conventional toilets. The benefits all boil down to environmental impact, cost saving and low maintenance. Here is a brief discussion on each of these benefits:
Wastage of water is one major contributor to environmental degradation. Humans use far too much water for their needs. All these at the expense of other natural organisms that also need water to grow and develop. The dual flush toilets usually feature high-efficiency flushes that use a minimal amount of water per flush to move waste mass.
This way, it saves a lot of water that could have been wasted with conventional toilets with single flushing mechanisms. Such toilets are usually compliant with NEPA and meet the WaterSense standards for water efficiency.
In a world where financial needs are limitless yet the resources to meet them are always scarce, wise people make savings by any means available to them. The lower water usage driven by the dual flush toilets translates into reduced water bills.
The initial cost of a dual flushing toilet can be high but ultimately, the toilet will save you thousands of dollars in water expenses.
The older toilets commonly referred to as single flush toilet use pressure siphoning system to get rid of toilet waste. This siphoning system may be efficient but extremely prone to clogging. At times, it may not mount enough pressure to move waste.
This way, it will require continuous monitoring to prevent dangerous clogging. Dual flush toilets normally use gravity. When the flushing system is activated, a trapway is opened and the wastewater flushes with pre-selected volume. This produces a clog-free operation.
How Do You Find the Best Flush Toilet?
We know that each person has his or her own taste and preferences. We have presented you our picks but we also understand that you may not find among them your desired model. Should that be the case, then use of this helpful buying guide to give your direction.
Here is what to look for the flush toilet:
Toilets are available in either of two styles: Single-piece or double-piece. The most common of these is two-piece style. It describes a toilet that has a bowl and a tank separately but bolted together. Such types are usually bulky and therefore occupy appreciable space. They also tend to be cheaper. Their spare parts are also easily available.
The single-piece models lack any seam between the tank and the bowl. As the name sounds, the tank and the bowl is one unit. The style is modern and compact with the ability to fit into smaller spaces. Since there are connecting parts where bacteria can hide, single piece toilets are generally easier to clean and maintain.
A rare toilet style that is gaining popularity with some individuals is a wall-hung or wall-mounted toilet. The only problem is that such models require unique plumbing that may prove challenging to add to an existing bathroom.
Waste modifications may also be necessary. The wall-mount style is gaining popularity, especially with new homeowners. If you are looking for the superior flush toilet then I would recommend a single-piece model.
Rough-in measurement is perhaps the most important consideration. The dimensions of the rough in will determine whether or not the toilet will fit into your bathroom space. Rough-in describes the distance between the wall in the rear of the toilet and the center of either the bolds that mount the toilet to the floor or the drainpipes.
This is especially important if you are replacing your existing toilet. Get the measurement of the rough in. Let it guide you in finding the best dual flushing toilet for replacement.
The new toilet’s rough in measurement should be a little bit lower than the original measurement. Standard rough-ins measure 12-inches but you can also find 10-inch and even 14-inch versions in traditional homes.
Toilet Bowl Shape and Height
There are two toilet bowl shapes you can choose from – round bowl or elongated (oval) bowl. Round bowls will save your bathroom space. They are also less costly. However, you may find them wanting when it comes to comfort and ergonomics. Elongated models are more comfortable and ergonomic. However, they tend to be expensive and consume a lot of space.
When it comes to height, you can choose between standard or universal height models. The standard height ranges from 14 to 15 inches rim from off the ground. The universal height (also known as comfort or right height) measures 15 to 17 inches off the ground to the rim. I would prefer the latter. An elongated bowl of universal height makes the best toilet.
The Flushing System and Tanks
The size of bowl tank is none issue because most models come with comparably sized tanks. What should tickle your curiosity is the flush valve size. It differs from one model of the toilet to another. The valve is located right at the center of the tank. It serves to release water reserved in the tank when the flushing mechanism is activated.
A larger valve releases higher flow rate with each flush compared to smaller valves. A higher flow rate translates into a powerful flush which is more efficient in eliminating waste materials. They work great with water-efficient models such as the ones we have included in our top reviews.
The two common flushing systems are pressure siphoning and gravity-assisted systems. The pressure assisted models to depend on pressure to force water down the valve into the trapway. Gravity assisted models are quieter and simply depend on gravity to move waste. Dual-flush models may allow both mechanisms to improve water consumption efficiency.
I believe you do not want to get yourself on the wrong side of the law. The federal government prohibits new toilets from using more than 1.6 gallons of water per flush. A good number of the high-efficiency models feature water consumption rate that’s much lesser than that the rate stipulated by the federal law.
Make sure you check the water consumption rate of your preferred flush toilet before you bring it home. Ensure you buy one that has low consumption rate. However, make sure that such consumption rate does not sacrifice the performance of the toilet. Also look for WaterSense and APA certifications on the toilet before you purchase it.
How to Fix Problems with Flush Toilet
You can be stranded if your toilet begins to have problems with flushing. Maybe flushing is incomplete, weak or inappropriate. Other problems may include leaky seals, clogs and slow emptying of the bowl. Here are some common problem and how to fix them:
Problem 1: Phantom Flushes
Phantom flushes define the water that trickles into the bowl spontaneously. This happens as though someone has activated the flushing mechanism yet no one did. Such toilets have a problem of cutting off and on spontaneously.
The problem is with what plumbers call a flapper or flapper seat. To solve the problem, just empty the bowl and the tank. Then you can check the flapper seat. Clean the flapper seat if dirty or replace it if damaged.
Problem 2: Water Trickling Into the Tank
This is the symptom of a leaky supply line. You will hear a hissing sound coming from the tank. In this case, look for any problems with the float, the bullock, and the refill tube or the inlet valve assembly. As water comes it the inlet valve, the hissing sound emanates.
It could be that the flat needs adjusting or is sticking. Go ahead and check the refill tube. Adjust it if necessary. If none of your efforts yield any results then you may be forced to replace the entire Bullock assembly.
Problem 3: Weak Flushes
A weak flush means the bowl empties slowly. This often results from clogged holes underneath the rim of the bowl. You can solve the problem by using a strong wire to gently poke into each hole to remove the debris. You can use the same wire to weaken any debris that may be blocking the siphon jet.
Problem 4: Leaky Seals
Any standard flush toilet has on it at least five seals. Each of these seals has potential to leak. In case of any leaks, check each of the five seals. If any of the seal’s leaks, tighten it or replace it altogether. Usually, the largest seal exists where the tank meets the bowl.
Any fault here will cause a major leak. To replace the seal, you will have to drain the bowl and the tank. You will be forced to turn the water up and down to access the seal better.
How To Fix Slow Flushing Toilet Tips
Problem 5: Clogs
Many people dread clogs for good reasons. They are simply risky to deal with. Unfortunately, clogs are the most common toilet problems. To remove a clog, you will need to have some sort of pump. You may use a force-cup plunger but it is only effective for small clogs.
For bigger and most serious clogs, use a closet auger. To unclog, insert the tip of the auger into the drain hole. You can then twist its handle while you push the rotor downwards. Be cautious not to damage your bowl.
At long last, we are in the last part. I hope you have found our review informative, comprehensive and thus helpful. If you agree then we are confident you are on the right path in your search for the flush toilet currently in the market.
