How Does a Tankless Toilet Work? 

Tankless toilets are a modern option for homeowners looking for a cost-effective bathroom renovation option. These toilets do not have a water storage tank that standard tanks have.

Instead, they are connected directly to the plumbing system. As such, most of them require the supply line to have enough pressure to cleanse the toilet bowl.

With the best commercial tankless toilets, this will not be a problem as water supply lines in commercial buildings operate at higher pressure levels.

However, installing one at home is a bit tricky as the pressure in most residential plumbing systems is too low to cleanse the bowl effectively.

To overcome this challenge, the best residential tankless toilets use a small electric pump to boost water pressure as it enters the bowl.

When the toilet lever is operated, water rushes into the pump where its pressure is increased instantly (before being discharged into the toilet bowl).

Added Pressure

In their design, most tankless toilets for homes feature a small electric pump built into the main toilet chamber. Water has to go through this pump before it is flushed into the toilet bowl.

Leading commercial tankless toilets do not require a pump because the pressure in commercial solving systems is high enough to cleanse the bowl thoroughly.

Flushometers

Tankless toilets use approximately the same amount of water as a tank-type toilet, but the water enters the fixture at a greater pressure.

This is often achieved by sending the water through the line at a higher rate of speed. However, the size of the feed pipe is also an important consideration in this case.

While commercial buildings and some residential buildings have enough water pressure to power such a flush without any mechanical assistance.

Such tankless toilets are commonly referred to as Flushometers. Flushometers vary in requirements, with most of them requiring water pressure of between 15 and 20 psi.

Types of Tankless Toilets

As the name suggests, tankless toilets do not have a bank. As such, they fall into the category of one-piece toilets.

These toilets do not have a seam in between the tank and the actual toilet. This means that the toilet is easier to clean and does not require much installation space.

Wall Hung Tankless Toilets

wall hung tankless toiletAnother type of tankless toilets you should consider buying is the wall-hung tankless models.

Rather than being installed on the floor like conventional toilets, these models are hung on a wall in the bathroom.

Such models are best suited for bathrooms that have a limited footprint. Most of the modern wall hung tankless toilets feature an easy to clean, sleek design.

With such a toilet, the toilet bowl and flushing plate will be installed on one of the walls in your bathroom. This results in a more streamlined appeal that will save up to 12 inches of space in the bathroom.

Floor-Mounted Tankless Toilets

If you would rather have a model that sits on the bathroom floor, there are several things you should consider.

The toilet has to be of the right size for your bathroom. This is because floor-mounted toilets require more space, as compared to wall hung tankless toilets.

One of the measurements you should take into account is the rough-in measurement.

This is essentially the measurement from the bolts that attach the unit to the floor to the wall behind the toilet. Most floor-mounted toilets in the market today have a 12-inch rough-in.

However, older homes may require a toilet with a 10-inch rough-in. If bathroom space is not a problem, you may also experiment with the best 14-inch rough-in tankless toilets.

Tankless Toilet Design

The design of a toilet is not just important for enhanced appeal. It also has a functional role to play. Again, toilets meant for public bathrooms must meet certain requirements.

While choosing the right tankless toilet for your bathroom, you also need to consider other aspects that will impact on spacing as well.

The design of your preferred tankless toilet model will also affect it’s ease of cleaning and use.

As such, you need to consider the following design aspects.

Seat Height for Tankless Toilets

How high is the toilet seat from the bathroom floor? This measurement should be taken from the top of the toilet seat to the bathroom floor.

Different tankless toilet models have varying toilet heights, ranging from 15 inches to 19 inches.

Basically, the various tankless toilet models available today may be classified into three broad categories based on their height.

Here are the main tankless toilet height options you should consider.

Standard Height

These are the toilets that have their seats positioned less than 17 inches above the bathroom floor.

Such tankless toilet models feature a low profile. As such, to they are only suited for people of smaller or average stature.

Chair/Comfort Height Tankless Toilets

In these tankless toilet models, the toilet seat is usually positioned higher than 17 inches above the bathroom floor.

Most of comfort height tankless seats have a height if between 17 and 19 inches. According to ADA requirements, such toilets are ideal for disabled people.

With the toilets positioned this high above the bathroom floor, people of all ages groups will have an easy time sitting and standing. As such, most of the best chair-height tankless toilets available today are ADA compliant.

Custom Height Tankless Toilets

What if you could have the toilet seat positioned at your preferred height? Well, this is now possible with the best wall hung tankless toilets in the market today.

Such toilets may be installed at most any height, between 15-3/8 inches to 28-1/2 inches.

As such, such a toilet will allow you to set the seat at a height you find preferable and comfortable for people of varying statures. Again, a raised toilet basin saves on space and makes it easier for you to clean beneath the toilet.

Bowl Shape of Tankless Toilets

This is the other design aspect you should bear in mind while shopping for the best tankless toilet.

You may have noticed that these products have bowls of varying shapes and sizes.

So, what toilet bowl shape and size is ideal for your installation or replacement project?

The right tankless toilet bowl shape and size will depend on several things. Here are the three main shapes you should consider, in this regard:

Round Front Bowls

Most traditional toilets have a round front for the bowl shape. In most round-front tankless toilet models, the bowl measures between 28-1/2 and 31-3/4 inches from the nose to the back.

Though considered to possess an older look, such toilets are known to save on space. However, such toilets are not as comfortable to use as the models discussed below.

Elongated Bowls

If you are looking for enhanced comfort in your tankless toilet, you should consider getting one that has an elongated bowl.

In this case, the bowl measures between 28-1/2 and 31-5/8 inches from nose to back. Such models are known to be very comfortable for people of different statues and ages.

Compact Elongated Toilets

Would you rather get a tankless model that couples a compact design with enhanced comfort?

In such a case, a tankless toilet with a compact elongated bowl would be the right choice. The comfort offered by such a bowl may be compared to that of an elongated bowl.

Even so, such a tankless toilet will save you about 10 percent of space in the bathroom.

Tankless Toilets Vs Tank Toilets

Whether tankless floor-mounted or tankless wall-mounted, tankless toilets differ from the standard two-piece tanked toilets in a number of ways.

The most evident difference is the design; while tanked toilets cone in a two-piece design, tankless toilets feature a one-piece design.

Discussed below are several other ways in which these two toilet types differ.

Tank Toilets

Traditional tanked toilets have two main parts: the tank and the bowl. The tank is often raised above the bowl. This allows for a powerful gravity-aided flushing effect.

When flushed, a valve at the bottom of the tank opens, allowing water from the tank to flow down into the bowl and push the wastewater out through a siphon, situated at the bottom of the bowl.

With regards to design, you will have a choice of two-piece and one-piece tank toilets. In either case, to will find tank toilets to be relatively cheaper, as compared to tankless models.

Tankless Toilets

These are costlier but more appealing than tank toilets. Similar to the tank toilets, water has to be delivered at high speeds to force the waste down the drain in a tankless toilet.

Since these units are connected directly to the plumbing system, without a water storage tank, they have specific water pressure requirements.

In this case, the water has to enter the fixture at high pressure. In cases where the plumbing pressure is low, water pumps are used to boost it to the required pressure.

Tankless toilets come in a number of appealing, sleek and space-saving designs. This makes them a preferred choice for many bathroom renovation projects today.

Tankless Toilet Pros

A tankless toilet, whether commercial or for residential application has a number of benefits to offer.

Saves on Water Consumption

Modern tankless toilets have outstanding water efficiency ratings.

This alone makes them an ideal choice for homeowners looking forward to visiting water efficiency in their homes.

Again, tankless toilets feature a dual-flush mechanism, which has been proven to save even more water. This is especially true with the more expensive models, like the ones made by TOTO.

Compact Design

The fact that these units do not require a tank means that they can be used in tight spaces.

If your bathroom is small, this type of toilet can save you a considerable amount of space. This is particularly the case for the best wall mounted tankless toilet models.

Fewer Complications

As compared to tank toilets, tankless models have fewer parts, hence are less likely to break down.

With a tankless unit, you will not have to worry about the floating balls, valves and inlet valve maintenance issues associated with a tank toilet.

This makes tankless toilet models cheaper to maintain in the long run.

Aesthetically Appealing

Modern tankless toilets feature sleek and appealing designs to complement any bathroom décor.

These toilets are renowned for their beauty and space-saving benefits. They will give your bathroom the modern appearance you desire.

Tankless Toilet Cons

Although they are a preferred toilet option for many homeowners, tankless toilets have a few downsides.

On average, tankless models are available at higher price points especially when they come with additional luxury features.

Again, the mist action is noisy in action in comparison to other toilet types. This is something you need to consider if you live in apartments where the shared walls are rather thin.

Common Issues and Problems Associated with Tankless Toilets

Ranging from leaks and toilet overflow to endless flushing, a tankless toilet is prone to a number of complications.

Here are some of the problems you should expect while dealing with a flushometer toilet.

Flush Issues

In rare cases, the tankless toilet may fail to flush entirely. This problem may be caused by a number of things, including a malfunctioning handle assembly.

The handle assembly on the toilet may jam or just break down, in which case the toilet fails to flush when the lever is operated.

This problem may also be caused by a faulty water supply valve or relief valve.

In other cases, the toilet may flush, but fail to deliver an adequate amount of water to complete the flush. When this happens, the toilet will initiate the flush successfully, but shut off almost immediately.

Another flush-related problem is when the ticket continually flushes for long periods without shutting down.

This results in lots of water rushing into the tankless toilet and may even splash bowl contents all over the bathroom floor. This problem occurs when the stop valve in the toilet fails to activate.

Toilet Leaks

Similar to conventional tank toilets, tankless toilets are known to leak from time to time. In most cases, the toilets leak from the handle.

Some are also known to vibrate abnormally while flushing, causing water to leak from various points.

Regardless of the problem you are having with your tankless floor mounted toilet, it is advisable to have a skilled professional inspect and repair it in time.

Tankless Toilet FAQ’s

Tankless Toilet Won’t Flush – What Should I Do?

This is often caused by a poorly seated flapper—a part that opens to let water flow into the toilet bowl.

The flapper is often attached to your toilet handle arm by a chain. This chain can sometimes become unhooked through rough usage.

You may also discover the chain or handle arm has broken; in which case it should be replaced. Finally, the flapper itself may be stuck due to corrosion at the joint or warping.

How to Flush a Tankless Toilet Without Water

The solution to this would be to flush the toilet with a bucket of water. You will need about a gallon of water to pour directly into the toilet bowl.

You should start slowly at first, then quickly add the remaining water into the bowl. The shape of the toilet and the pressure from the water in the bucket will push everything through the pipes.

Tankless Toilet Keeps Running – What Should I Do?

This problem may be caused by a number of things, all of which have different remedies. For instance, it may happen because the relief valve is not seating properly or the bypass orifice in the unit is clogged.

If this is the cause, you should disassemble the working parts and clean them thoroughly. Running toilet may also occur if the inside cover is damaged or cracked.

In this case, you need to replace the inside cover. If the line pressure has dropped too low, it may be insufficient to force the relief valve to seat. This will also cause a tankless toilet to continue flashing.

If this is the problem, you should shut off all control stops until the pressure has been restored, then open them again.

Noise Coming from Tankless Tank

This may also be caused by a number of things. If you find your tankless toilet to be too noisy, the problem could be a leak in the toilet valves.

A malfunctioning fill valve or just accumulation of calcium deposits in the pipes. Once you have ascertained the real cause of the noise, you should either clean or replace the affected part to reduce the noise.

Low Water Pressure from Tankless Toilet

With continued use, tankless toilets may develop a lazy or weak flush. This is commonly caused by a buildup of minerals such as calcium and lime, along with debris particles such as rust in the rim feed and jet holes.

To clear the jet, you may use a wire hanger. You need to make a small hook at the end of the hanger. Push the hanger up into the jet hole to fish out any debris that may be trapped in the jet passageways.

Tankless Toilet Installation Tips

As important as they are, toilets get old or break down with time.

When this happens, you will need to replace them with the best commercial tankless toilet models.

Whether it is a toilet replacement or are installing a toilet for the very first time, you just have to do it right.

For DIY tankless toilet installations, here are a few pointers to help you install the unit correctly:

Inspect and Replace the Flange

For replacement projects, you need to inspect the old flange for damage. If the flange is damaged or cracked, you have two choices; replace the flange or use a flange repair ring to reinforce the cracked one.

Though a temporary solution, this will hold the bolts to the floor more securely. Once complete, reattach the new flange or flange and repair ring to the floor using screws.

You may also use a drill bit to place your new bolts inside the flange before removing the rag from the sewer pipe.

Set the Toilet Bowl

You need to ensure that the closet bolts set are upright within the collar slots of the flange.

If so, place a brass washer around each bolt. While doing this, you have to ensure that the wax ring is thick enough for the floor beneath the toilet.

You may now proceed to line it up with the flat side down over the flange while pressing it into the pipe.

You should then line the bowl of the toilet over the ring and bolts carefully, probably with the help of a friend, before lowering it into position.

Be very careful not to twist or rock the bowl in the process, as doing so will break the wax seal and cause the toilet to leak.

With the bowl in place, press the bowl firmly into the wax seal and use a level to ensure that it is sitting evenly on the floor.

If the bowl is uneven, you may add waterproof or stainless-steel shims beneath to balance it out. For minor variations, a few stainless-steel washers will suffice.

Attach the Bowl to the Floor

Having positioned the bowl, you should place another washer and nut on top of each bolt and tighten them to secure the bowl.

Tighten the nuts alternatively so as not to apply too much pressure to one side of the bowl (this may loosen the wax seal).

Be mindful of the direction of the wrench as well to avoid cracking the porcelain. Once you are done, cover each bolt with a bolt cap.

At this point, you may also trim each bolt using a hacksaw. Having installed the bowl, you should now connect the toilet to the supply line.

For this stage, you should follow the manufacturer’s instructions as the procedure varies from one model to another.

Ready to Install a Tankless Toilet in Your Bathroom?

Affordability, ease of use, water efficiency and performance are some of the most important things you should consider while shopping for a conventional toilet.

The choice of a tankless toilet is even more depending; requiring you to consider even more aspects—as you have learned throughout this guide.
