Toilets are an integral part of our lives, and we rely on them every day. There are two styles of toilet: two-piece and one piece. Macerating toilets are toilets that blend human waste into slurry to make it easier to pass through the plumbing.

An up flush toilet system flushes the slurry upwards, making it possible to have toilets in the basement. If you are considering purchasing a macerating toilet, please use this review to help decide.

How Does a Macerating Toilet Work?

Unlike standard toilets, a macerating toilet works by blending waste into a slurry with metal fans for around 15-30 seconds. Once that is complete, a drain pump pushes the slurry up to the nearest drain line.

Some great features of macerating toilets include:

  • Efficient pump system
  • Two different blades
  • Bowl sits on a pedestal
  • Large pipe in the back
  • Same flush as a standard one

It is worth noting that some models can be used in RVs and boats, as well as in homes and apartments.

Some of the drawbacks of macerating toilets include:

Macerating Toilet Buying Guide

Blade Quality & Pump Power

The main qualities of macerating toilets are the powerful pump and sharp blades; these two parts, in particular, need to be high quality. Lesser quality blades and pumps will only cause more problems in the future. Make sure to carefully read the customer reviews and product description to get the best upflush toilet for you and your home.

Ease of Installation & Maintenance

Macerating toilets are typically easy to install with the right equipment and clear instructions. Having the right gear, the product manual, and a video tutorial go a long way, but also confirming that your home can support an upflush toilet beforehand will save you a lot of potential headaches in the future. However, if installing a toilet seems overwhelming, we recommend bringing in a professional to help.

Wattage & Rated Voltage

While some macerating toilets run on battery power, a lot of them have various wattage or voltage levels. Each model has a different power level, so make sure to confirm what your home can support and read the product description carefully beforehand. This is the best way to ensure that you get the best upflush toilet for your money.

Water Consumption

Typically, macerating toilets are better at conserving water during use than standard toilets, but it is possible to adjust the water levels on some models.

Look carefully at the parts and manual to see if your macerating toilet’s water consumption can be adjusted. If you are unsure what GPM to get, 1.6 GPM is a great place to start.

Eco Friendly

Dimensions

There is not really a standard size for toilets, but they often range between 23 and 28 inches deep, 13 and 20 inches wide, and 15 to 18 inches high. The exact specifications will change depending on the shape of the bowl, whether it is a comfort or standard toilet, the brand’s personal preferences, and more. Measure your bathroom carefully and use your existing toilet as a guide when choosing a new toilet.

Bowl Type & Style

In America, there are two styles of toilets; round and elongated. Round toilets are the more traditional and 'standard' style, whereas the elongated toilets are a modern innovation that increases comfort while the toilet is in use. The size of your bathroom and personal preferences will let you know which style is best for your home.

Aesthetics & Design

When renovating a bathroom, we know that you choose every piece and item carefully to fit your design aesthetic. Do some research online to find your perfect toilet style and hunt around to see if a macerating version of that dream exists. A toilet that compliments the style of your bathroom will really tie the room together nicely.

Price & Warranty

Macerating toilets are designed to last as long as standard toilets, meaning that with proper care, they can last for up to 10 years. In terms of warranties, this will vary depending on brand, model, and store, but they typically last between one year and a lifetime.

Make sure to read the product descriptions and company warranty policy carefully before purchase. It is also worth remembering that, as with all toilets, there is both the upfront cost to consider as well as the maintenance and repair costs in the future. Typically, macerating toilets are more expensive upfront and then cheaper to maintain in the long run, but this can vary.

How to Clean & Maintain Macerating Toilets

Cleaning and maintaining a macerating toilet is key to ensuring that it continues to function flawlessly for as long as possible. Choosing a model with a powerful flush helps with passive cleaning, but inspecting and cleaning your toilet thoroughly every week is essential. Descale your toilet and check the fans every month to prevent blockages or other issues.

Common Upflush Toilet Problems & Fixes

Why won’t the toilet turn off?

Constant flushing means that there may be damage or blockage within your macerating system. Turn off the water supply and look for blockages in the macerator, pump, and waste outlet pipe. Alternatively, the return valve may be faulty and need to be replaced.

The toilet is running but not pumping out

The waste pipes may be frozen or damaged. Warm-up and insulate the pipes thoroughly and be prepared to remove part of the waste if necessary.

Why does the macerating toilet smell?

This could be caused by limescale or human waste buildup. Clean out your toilet and descale it a couple of times.

Why is the toilet making a horrible noise and vibrating?

Usually, this is caused by something lodged in the blade itself. Remove the blockage with pliers immediately.

Why is my toilet leaking?

Typically, this is caused by a substantial buildup of waste, a worn rubber membrane, an old motor, or a shrunken rubber waste outlet. The first cause can be cleaned up, but the latter three should be replaced as soon as possible.


Frequently Asked Questions (FAQs)

How long do macerators last? How long do the pumps last?

Macerators are designed to last as long as toilets, which can last 10-15 years with regular care and maintenance. The pumps can last around 5 years or so.

Are Saniflo toilets any good? Do they smell?

Macerating toilets are not designed to smell. If they do, this is typically caused by waste or limescale buildup. This can be avoided with regular descaling and cleaning.

Are batteries always required?

Not necessarily. Read the product description and instructions carefully before purchase.

What is the best Macerator pump for RVs?

While there are plenty of good macerator pumps for motor homes and RVs, we would recommend this particular model from Amazon.

Do I need to hire a plumber to install a macerating toilet? What’s the average installation cost?

The cost to install a macerating toilet varies depending on the time taken, your area, and how complicated the installation for that model is. That being said, it can cost between $150 and $800.

How can I unclog a macerating toilet?

If you need help unclogging a macerating toilet, please see this video for more information.

Where is the best place to buy upflush toilets?

While the brand store or your local hardware store are good places to look, we would recommend Amazon for its large selection, regular deals, and a wealth of customer reviews.
