What is A Marine Toilet?

There are different types of marine toilets, manual or electric-like the tmc electric marine toilet amongst others, and they are perfect for all types of marine vessels. Below is a quick review of the best marine toilets available.

How Do Marine Toilets Work?

Before you consider buying a marine toilet, you need to know the various types of marine toilets that are available in the market to know how they work, so you can choose the best marine toilet that suits your taste.

Manual Marine Toilets

Manual marine toilets are the types that require manual pumping to work. As the most common type of marine toilet, users can manually pump in either saltwater or fresh water to help drain the toilet.

A manual marine toilet is quite easy to set up as it does not require electric components and it’s also cheaper.

The major disadvantage associated with manual marine toilets is that they can clog easily and it takes some practice to know the proper way to use them as not everyone is familiar with them due to its hand pump system.

Electric Marine Toilets

Compared to a manual head, the electric marine toilets are electrically powered and the pumping function is automatic. With a simple push of the button, the entire pumping and waste system disposal cycle is done.

An electric head contains a built-in macerator in the unit which grinds up the solid waste for easy waste disposal and a scavenger pump.

Electric pumps are very easy to use thanks to the system inculcated into them, and this makes them a good choice for people who need a quick-action marine head.

On the downside, it has high power consumption as the electric pump requires a good deal of battery power and also uses a large quantity of water, that is why an electric marine head with a large liquid tank is advisable.

Portable Marine Toilet

A portable toilet is a perfect choice for small-sized boats and sea vessels or vessels that have small spaces for the bathroom.

The portability spans from their composition which is a combination of a water tank at the upper part and a holding tank which is the waste tank at the lower part.

They are good options for a short or one day-long trip, but not suitable for more extended trips as the waste tank needs to be emptied often.

Composting Toilets

Composting toilets are eco-friendly types of toilets and are the newest in the category of marine toilets.

A composting toilet contains two separate parts or compartments; one for liquid waste and the other for solid waste, a dry compartment.

Composting heads work on a mechanism that allows the solid waste to be mixed with components like peat moss, after which the composting process then commences in the composting tank.

Unlike electric toilets, manual toilets, and portable toilets, the composting toilets do not utilize water.

The entire composting process leads to less odor and it’s quite environmentally friendly.

The downside of a compost toilet is that if done wrong the entire process can lead to bug infestation.

How To Operate A Marine Toilet?

Marine toilets work like the usual products at home with a few minor differences, which nonetheless are set up to ensure proper functioning.

The minor differences in functionality are based on the various types of marine toilets. For instance, while the manual ones have most of their functionalities being carried out manually through a manual pump, the electric toilet requires some power to function. Most of its processes are automatic; some others come fitted with functionalities to prevent flooding, waste backflow, etc.

Be sure to find out the installation and function instructions set for each type of toilet to ensure that you operate it appropriately.
