Macerating Toilet: What is, How it works, Pros Cons

Macerating toilets are suitable for residences that wish to build a toilet where it might otherwise be impractical. Since they do not need special plumbing and can be mounted wherever there is an electricity and water connection, macerator toilets go in easy, seamless, and cost-efficient – there is no need to demolish floors or pour hundreds of dollars into the plumbing.

This article explains how the macerating upflush toilet system functions and provides you with an in-depth look into its applications, benefits, and drawbacks. Plus, many of the commonly posed questions about macerating toilets have been answered.

What is a Macerating Toilet?

The term macerate means to break, crack, or melt something into tiny pieces. Macerating toilets send the waste to a macerating machine situated behind the toilet or inside the wall. There is a high-powered stainless steel spinning cutting blade within the maceration device, which shreds and disintegrates human waste and toilet paper into a fine, liquified paste. When the waste has been liquefied, it is forced through the pipe attached to the main sewer line.

Macerating Toilet vs Standard Toilet: What’s The Difference?

A standard toilet, when flushed, sends the waste down into the drain lines. Since the drain line is below the bathroom floor, gravity draws the waste material towards it. The same goes for sinks and bathtubs.

Macerating toilets, on the other hand, transfer waste to a macerating machine positioned behind the toilet. Inside the macerating unit, there are high-powered blades that mash the solid waste into liquid form. The waste is then pumped out of the macerating unit into the standard pipe that is connected to the main sewer line.

How Does A Macerating Toilet Works?

If you flush a toilet with a macerator toilet, the waste is first transferred to the macerator behind the toilet. It is encountered there by a spinning grinding blade that runs with an amazing pace, smashing solid waste and stuff like toilet paper into a liquefied paste.

Below is a comprehensive description:

  1. First, the waste leaves the toilet bowl as usual.
  2. The waste is then guided to the macerator unit behind the toilet, rather than immediately to the outflow.
  3. When the waste enters the macerator device, the internal receptors of the unit are triggered in the macerator unit. And hence the cycle of maceration begins.
  4. The blade within the macerator unit spins at a rate of up to 3,600 rpm and slices solid waste into a fine liquid paste.
  5. Once this step is finished, the unit pumps the liquid fluid into the pipe attached to the main drainage lines.

*Each macerator toilet has a separate pumping power to discharge liquid waste through the pipe into the drain line. Depending on the model selected, most will reach vertical pumping distances of five meters (15 feet) and horizontal distances of 50 meters (150 feet), or maybe more. In addition, certain toilets also have a one-way valve in the unit to avoid any risk of backflow of liquid waste.

Where To Use A Macerating Toilet?

If you are located far from the main sewerage line for your plumbing or the toilet needs to be installed in the basement with drain lines that are on the ground floor, a macerating toilet has got you covered.

They are perfect for a variety of scenarios, for example, whether it is a basement-turned-bedroom or a workshop toilet outside of the property, provided they are placed inside the main drain line radius.

*This range is calculated by the pump’s strength and ranges from model to model, typically about 10-15 feet of vertical lift and 100-150 feet of horizontal run. Most units have external inlets to connect up a sink or tub. Macerating toilets can also be used with septic systems.

It’s not too costly and can be built in your living space without needing to execute a massive plumbing upgrade to get another toilet.

Can macerator toilets smell?

Yes, and No. A good quality macerator unit has the power to pump liquefied waste as far as possible into the main drain line. A poor-quality macerator may smell on several occasions. This is because of the accumulation of human waste in 2-3 inches of water that is left in the pipes due to the inefficiency of the macerator unit to transfer the waste deep into the sewer lines.

The Benefits of Macerating Toilet

1). It can be installed anywhere in the house.

Saniflo toilets can be installed virtually everywhere in the household, independent of the drainage system or plumbing configuration. Because the toilet system is upflush, it is an ideal complement to a cellar bath with an upward waste flow. You may also mount them in places not originally designed for a bathroom, such as an outside workshop, a spandrel under the stairs, or a similar spot. The waste goes straight to the outside drainage or septic tank.

2). It is portable.

Macerating toilets are portable. Unscrew it and transfer it to a new location. That’s why they’re beneficial for households that shelter the aged or disabled. Most of the systems need zero drillings or breaking.

3). It makes it possible for you to have a toilet, even though there is no underground drainage system.

You can mount this toilet basically anywhere, due to the special architecture of the Saniflo system (within a particular range of the main drain line). To function properly, other toilets need an underground drain line of some kind. That ensures that when a full-time extra toilet can not be appropriate for your house, a macerator toilet may still fulfill your temporary needs.

The Drawbacks of Macerating Toilet

1). Produces loud noise.

For a normal toilet, the noise levels are restricted to flushing, draining, and refilling of the tank. But Macerator Toilets feature one more additional step of motors grinding the solid waste – that is pretty noisy as well.

2). Macerating toilets appear to get clogged more frequently than not.

Upflush toilets need a particular pattern of usage to protect them from being clogged. Not only is the waste going upwards, but the dilemma of waste not being adequately macerated in the tank is still present. When using this sort of machine in every household, you must be vigilant about what you flush. If there are clogs, you are restricted to the items available to return the machine to its proper function. Many owners of a Saniflo toilet feel that with this device choice, their repair or maintenance costs are greater, contrary to that of a standard gravity toilet.

3). Can’t be used without electricity.

Macerator toilets can’t work without electricity. This is because, without electricity, the grinding pump would not work.

4). You have to abide by the building codes.

Before constructing a macerating toilet, you must validate the municipal building codes. While according to national and foreign building codes, macerating toilets are allowed, there are many areas where local housing codes prohibit them from being used.

5). They have a short life span.

For the typical household, most good quality Macerating toilets last for 10 to 15 years only.
