What Is A Macerating Toilet?

A macerating toilet is a type of toilet that chops up and liquefies solid waste to make it easier to move through pipes. Macerating toilets have a rotating blade that grinds solid materials like toilet paper and solid waste, so its far easier to pump thru small pipes with little pressure. This makes them the best toilets for basements.  (Source).

How Long Do Macerating Toilets Last?

Macerating toilets typically last about 15 years. They last as long as any other toilet, despite their extra equipment. All Saniflo toilets are guaranteed for up to 50,000 flushes.

How Much Do Macerating Toilets Cost?

Also referred to as Macerating toilets, macerating toilets are designed to on top of your floor, so there’s no need to install new plumbing.

The price of a toilet basically depends on its make and model. Most Macerating toilets cost between $800 and $1,600 each.


How Does A Macerating Toilet Work?

These toilets grind up solid waste and liquefy it. It can then be carried to the waste drain pine as small as 1 inch in diameter.

A macerating toilet features a blending or grinding mechanism that is designed to reduce human waste into a slurry before moving through plumbing. Macerating toilets are useful in cases where the water pressure is too low, or the toilet is being installed a considerable distance below the sewer drain pipe.

In contrast to conventional toilets, these toilets send the waste into a macerating unit that is situated either behind the toilet or in the wall.

Once in this unit, high-powered blades liquefy the waste, which is then pumped out of the unit through a normal pipe connected to the main drain line.

Is It Hard to Install A Macerating Toilet?

Macerating toilets aren’t generally hard to install, but some models may prove tough to install on your own because of their weight. These toilets are actually easier to install than conventional toilets because you don’t have to cut into the floor to install them.

Buyer’s Guide: What To Look For Before Buying 

Water Consumption

You want a toilet that does the job you bought it to do, but ideally, you also want a unit that’s efficient. The less water your toilet consumes, the less each flush will cost you in water bills.

The water consumption of toilets is measured in gallons per flush (GPF). Around 1.6 GPF is a good standard to aim for. This won’t be a big drain on your water supply, but it’s enough for the toilet to do its job effectively.

Consider The Power Required

Regular toilets don’t require a power supply to work. But due to the pump and spinning blades they contain, macerating toilets do.

It’s important to consider how much power your toilet needs. Higher power usually means a stronger toilet that can push waste further to where it needs to go. However, it also means higher water bills.

Some macerating toilets run on batteries. This makes installation a breeze and means that such toilets can be used in areas where the power supply is unreliable or non-existent.

Be aware though, that batteries need to be replaced, which can add to both the time and expense of maintaining your toilet.

Macerating Toilet Design

If you’ve spent a lot of time making your bathroom look nice, you don’t want to ruin it with an ugly toilet. Luckily, macerating toilets these days are available in a wide range of different sizes and styles to fit in with bathroom decor. Specifically, you don’t want to choose a toilet that takes up too much space or one that’s hard to clean.

Comfort Of Macerating Toilets (Macerating)

The comfort of your Macerating toilet is an aspect that is often overlooked. But it does matter, and it’s worth thinking about before you make a purchase.

In particular, the height of your toilet has a big effect on its comfort and usability. And this is even more important for families, where multiple people of varying sizes and ages could be using the same toilet.

Where possible, it’s a good idea to at least sit on any toilet you’re thinking of buying. There’s no need to feel embarrassed.Using the toilet is something every one of us does every day, so you want to make sure you’ve made the right decision.

How To Install A Macerating Toilet 

Macerating toilets use a rather unique waste discharge mechanism but are easier to install.

Check to see whether you need one, as building regulations mostly apply to drainage, plumbing, and ventilation systems.

Macerator Placement Considerations

For most macerator toilet systems, the macerator is a tank that sits behind the toilet itself. The toilet feeds directly into the macerator, which processes the waste and wastewater before evacuating it through a discharge pipe with the aid of an electric pump.

The macerator may also serve other bathroom fixtures, including a sink or shower, but can serve only one toilet. In many cases, the tank and its plumbing are all visible in the bathroom, but they may be concealed as well.

You may install the tank in the wall behind the toilet. To do this, you will require a longer extension piece to connect the toilet.

Go Vertical With The Waste Pipe

If your waste pipe needs to travel up at any point, keep the vertical portion as close to the macerator as possible.

There are limits to how long a discharge pipe can be. Again, note that every foot of vertical height is equivalent to 10 feet of horizontal run.

Lay the pipes strategically to avoid running out of allowable distance. The discharge piping can have only one vertical section.

Horizontal runs use gravity to move the waste, hence it should be installed with a standard 1/4 inch per foot downward slope as you approach the main drain.

Electrical Connections

Even with some of the best macerating toilets, this type of toilet requires a connection to electricity. To make this easier, you need to have an outlet installed close enough.

This outlet should be located more than 40 feet  away from the shower. Since it is a bathroom installation, you need to make sure that the outlet is a Ground Fault Circuit Interrupter (GFCI) outlet.
