Understanding Cassette Toilets

Casset toilette is normally a built-in part that is permanently fixed especially in motor homes, boats, and vans. It was built with the convenience of a home washroom in mind for occasional use in MWDs. The toilet consists of two main parts: a seat that is fixed and a waste tank that can be removed. It can be detached from outside the vehicle and dumped at the designated spots for waste disposal.

Some people say cassette toilets produce a strong odor, but this is not true nowadays. Green and yellow seals as well as clever venting systems used to make these toilets odor-free. They usually incorporate a flush mechanism that utilizes the vehicle’s onboard water to create a more conventional flushing procedure just like in residential toilets. The capacity to store waste in the size of cassette toilets is between 12 to 20 liters, therefore it is enough for use for several days if no one is using it or waiting for 2 days if one or more people are using it.

Exploring Porta Potties

However, a porta potty, another term for portable toilet unit, can be situated almost anywhere because of its “stand-alone” design. These are indispensable in situations such as parties, building sites, or any place where there are no permanent toilets. The portable toilets are completely self-contained houses of kinds that do not need connection to any outside sources. They are provided in a set of toilet seats which are fixed over a very big waste tank that contains the chemical solution which just reduces the waste breakdown and lessens the odor.

Porta potties come with a basic ventilation system and are usually not flushed. The sludge and chemicals go to a unit where they stay until the unit is serviced. Then a vendor comes and pumps out the waste chemicals and fills it with sanitizing chemicals. The volume capacity and maintenance needs can widely change per the model and the frequency of service in which the side is used, but this type of cassette toilet is usually less comfortable and less homelike than cassette toilets.
