The main difference is how waste is moved. Traditional flush toilets use water to push waste away, while the Solarid Toilet uses a mechanical piston to do the job without any water.

This approach results in a lower environmental footprint and significantly reduces upfront costs because it eliminates the need for a septic tank or leach field.

The Solarid Toilet and incinerator toilet work very differently. An incinerator toilet burns waste into ash, which requires significant energy and has higher operating costs.

In contrast, the Solarid Toilet uses a mechanical flush system to move waste into a pit, chamber, or tank, with much lower energy use, fewer moving parts, and lower overall operating costs.

Once the toilet has been flushed, the system is completely sealed off from the waste tank and is odor-free. The tank has a separate exhaust to vent gases.

Yes. The toilet ends with a standard 6" PVC coupler. Most composting or holding tanks either have a 6" or smaller opening, or can be modified to fit this connection.

No chemicals required.

If you're using the toilet in an RV or enclosed space and need to add enzymes to help control tank odor, you may still continue to do so with the Solarid Toilet, though this isn't necessary for normal operations.

The Solarid Toilet works very similarly to a traditional flush toilet — simply step on the foot pedal, wait a few seconds, and the internal piston system pushes the waste away.

It’s simple, intuitive, and waterless. One key difference: Do not use the toilet while the piston is in motion (i.e., during its "flush" cycle). Doing so will cause waste to be pushed in the wrong direction.

Don’t worry! There’s a built-in safety system to manage this if it happens accidentally.

While the Solarid Toilet is more forgiving than a standard flush toilet, it’s best to follow the same rules about what can be flushed.

To keep the system running smoothly and avoid clogs:

Do not flush items that could clog the pump truck’s hose, such as diapers, cans, bottles, or other bulky objects.

Avoid flushing dirt, sand, or gritty materials, as these can get trapped between the piston head and the waste chute, potentially causing damage.

You’ll need to wait about 28 seconds between flushes for the standard model and 16 seconds for the compact model.

That’s how long it takes for the piston system to complete its cycle. Once the motor stops running, the toilet is ready to be used again.

Note: The toilet cannot be used while flushing. A pressure sensor in the seat prevents the piston from activating if someone is sitting, helping avoid accidents.

The emptying frequency depends on the type and size of the containment system connected to your Solarid Toilet — such as a pit, composting chamber, or holding tank.

We recommend consulting your specific containment system manufacturer for guidance tailored to your setup.

As an example, a typical household of 2 adults and 2 children, where one adult does not work at home, using a standard 250-gallon waste tank, will want to have the tank emptied an average of once per year. 

Yes! The Solarid Toilet can be powered by solar energy or any power source that provides stable 12V DC power.

You'll need to pair your solar panels with a battery system to ensure consistent operation. This allows the toilet to function reliably even when the sun isn’t shining.

It’s a great option for off-grid setups, cabins, or mobile homes.
