Upflush toilet problems, Repair Tips

Let’s talk about upflush toilet problems. Upflush toilets are now becoming widespread in homes with basements, or limited space for traditional bathrooms. These unique toilets permit the elimination of waste by flushing at the bottom of that line. But, there are some frequent issues with the flush of toilets that you must learn how to handle.

For instance, constructing an efficient macerating system that’s efficient and quiet, while remaining small enough to fit in tiny areas is often a major challenge. Macerating pumps have many advantages and disadvantages.

While they need only a little plumbing and work well in bathrooms in basements, they can break, block or break in the course of time which is why you’ll need to master a few tricks to resolve these issues.

Upflush Toilet Problems

Although they are highly regarded by people due to their ease of use they also have some drawbacks. Among them:

1. Costs that are high at the beginning

Upflush Toilet Problems, Repair Tips

The set-up costs associated with an upflush toilet are higher than a traditional toilet. Especially in the case of most well-known brands such as SaniFlo upflush toilets (here are some upflush toilets reviews). The cost for the same toilet is around 1,000 dollars. A gravity toilet that is standard costs approximately 500 dollars, making the upflush model about two times the price of a gravity model. While it is possible to install the upflush toilet on your own, many will require a qualified plumber to set up and it will cost more.

2. Needs frequent priming

The pump that is used in upflush toilets has to be primed at least every day. The priming process is completed with flushing. It means that you only require the toilet at least once per day to ensure that the pump is fully primed. If you do are away from your home for a time it is necessary to be able to prime manually the pump in order to get it to work.

3. The loudness of the environment is high

The loudness of the environment is high

The gravity toilet has only one flushing procedure where water is pumped from the tank of the toilet into the toilet bowl and then into the drain. Upflush toilets are comprised of two main steps. The first is that the toilet flushes in a similar way as a gravity toilet. The waste ends up in a tank in the wall or another suitable place. The second phase will involve the pump that pumps the wastes through the drain, the main sewer line (even the shower drain).

The second one is quite loud due to the fact that it involves the pump working. For some it can be irritating and using a toilet in the evening can be noisy and chaotic. Therefore, it is important to pick the right location for your house where the noise of the toilet will not be an issue.

4. It is important to comply with building codes when installing the toilet.

Even if these types of toilets are approved to be installed at a national level, local regulations may make it difficult to install these toilets since some people aren’t comfortable with their use. This is different from gravity toilets, which have no restrictions on their installation.

5. Predisposed to blocking

Predisposed to blocking

Upflush toilets are made to hold waste and toilet paper. There is only that. If you insert any other items the toilet could get clogged with debris and cause it to be difficult to use it. If, during the construction phase, you didn’t include an easy way to clean this toilet could need to tear down the wall in order to access the pump and clear it.

The solution is to get an upflush toilet system that has the ability to break up debris into small pieces. This allows you to place in the toilet things like diapers and other items while the toilet is working to cut them into pieces and then send them down the drain.

6. Are there warranties for short durations?

Are there warranties for short durations?

Although upflush toilets can have a long life, however, the majority of vendors provide around 2 years of warranty. Also, since the warranty begins when you purchase the toilet this means that the warranty you get is smaller. Toilets with gravity typically come with at least three years of warranty, which is a lot more durable.

In addition, the warranty only covers the use of the toilet when water is utilized. That means other liquids aren’t covered.

7. Power outages can adversely affect your

Since the pump in the toilet with the upflush function requires electricity for its operation and it is dependent on the power supply to function effectively. If your region is prone to a lot of blackouts, and you own one or two bathrooms, you might think about investing in an electric generator or another backup source of energy. If however, you only have one flush toilet, there is no need for it as you can utilize the other toilets if there’s no power.

They won’t, however hinder you from purchasing upflush toilet, given the advantages listed given below.

Breaks Of The Upflush Toilets, Tips For Fixing

1. My Macerator Keeps Starting Randomly

My Macerator Keeps Starting Randomly

If the pump continues to fire randomly throughout the night or day, even without pressing the button it could be an issue in the microswitch.  This is one of the common upflush toilet problems. The issue could be due to an issue in the membrane of rubber which triggers the switch, or it could be caused by debris that has accumulated between switches and floors.


  • Microswitch not firing: If the issue is caused by a microswitch that is not firing, look for an external object in the space that is between the switch and the tank floor. This could make the switch think it is full, and initiate the flushing. Make sure to remove any waste that is accumulating near the microswitch before resetting the pump.
  • The membrane of the rubber is damaged: When the membrane’s rubber is worn out or loses its seal the water that is leaking out can get into the switch, causing it to fail. If this happens it is necessary to replace the membrane as well as the switch. Check whether you can determine if the switch is at the incorrect place.

2. My Macerating Toilet Keeps Running And Will Not Switch Off

One of the biggest issues that plague Macerating pumps can be that they sometimes fail to shut off. If you know how upflush toilets a working, there is will be no problem to fix it. The pump could flush and continue to flush, even after the macerator has been cleared.

Most of the time, identifying the cause of this issue isn’t simple. It could be caused by a single issue or a mix of problems, such as:

  • A blockage of the macerator or pump.
  • Blockage of the drain, waste pipes that leads to the drain system that is external
  • The pump’s rubber membrane
  • A microswitch that is not working properly


  • The macerator toilet is blocked: Shut off power to the pump from the mains supply, and determine if there’s an obstruction within the macerator unit of the pump. If there is, you can clear it by using a pair of small-nosed pliers, as you move the blade counter-clockwise.
  • Blockage of the pump: Check to see for cotton buds or other debris is blocking the impellers. Remove the obstructions. To get access to the pump, pull the motor from the unit, then turn it upside-down.
  • The waste pipe is blocked: Be sure to check whether the return valve is blocked since this could be able to bring the waste back in when it passes through the blockage. To remove this waste outlet pipe blockage you can use pliers with a thin nose to take off the lid from the upflush unit. Clear any obstructions within the valve for return. Sometimes the return valve may be damaged and requires replacement.
  • The microswitch is not firing: A microswitch that’s not firing is another frequent issue for upflush toilets. Solid waste can be entangled between the switch and tank floor causing the switch to believe that the tank is filled and requires flushing. In this case, it is necessary to clean the tank by hand and then restart the pump.
  • Rubber membrane that is damaged: The unit’s rubber membrane could be damaged and result in endless flushing. The membrane of rubber is the thin layer of rubber that water presses against to turn on the pump. If it gets damaged or loses its seal in the event of a leak, water could enter the switch, causing the switch to malfunction. However, if your macerating toilet remains in its warranty it is expected that the manufacturer will pay the cost of replacing it.

3. My Upflush Toilet Is Vibrating Violently

If your macerator/pump makes an unsettling sound every time it is flushed, there may be an unintentional object stuck in the blade of the macerator. It is possible to work on the problem and repair the problem yourself or contact a service plumber.


Switch off the power supply to the pump from the mains source (Never take off the lid of the macerator in the event that the pump is not turned off). Take the cover off and inspect the inside of the macerating toilets to see if there’s an object of foreign origin that has tangled the blade. Make use of a pair of thin-blade pliers to cut off the obstruction as you turn the blade counterclockwise.

4. My Macerator Is Running But It Is Not Pumping Out

This issue usually arises when the pipe that is used to dispose of waste is frozen, particularly during winter.


The first step is to turn off the macerator unit, then try to eliminate any waste by hand particularly if the waste is about to overflow. Apply hot towels along each side of the pipe to aid in releasing the blockage, and then eliminate the waste.
