Are you looking to hit the road in an RV but have no idea how to get everything up and running? One very important component of any recreational vehicle is understanding how its toilets work.

In this article, we will look at exactly how RV toilets work and provide helpful maintenance tips for keeping them performing optimally throughout your escapades.

Toilet trouble can quickly ruin a trip, so it’s essential to understand the inner workings of your RV toilet before you set off on your great adventure.

How does an RV toilet work?

RV toilets are different from traditional residential toilets in several important ways.

First, RV toilets use a combination of water pressure, gravity and suction to flush out waste. The force of the water creates a vacuum that sucks out the contents and sends them through a standard three-inch sewer hose into the nearby sewage system.

Additionally, most RV toilets use a storage tank located beneath the toilet to collect waste. This tank must be emptied and cleaned out on a regular basis in order to keep your RV’s plumbing system functioning properly.

Types of RV toilets

There are several different types of RV toilets available on the market today. These include:

Gravity flush

This type of toilet uses a combination of gravity and water pressure to flush out waste. The tank is usually located beneath the toilet and must be emptied regularly.

Vacuum flush

A vacuum flush toilet uses suction instead of gravity to flush out waste. These toilets usually require less maintenance than gravity flush models and can be more expensive.


A composting toilet uses natural composting methods to break down waste into compost or fertilizer. It is a great choice for those looking for an eco-friendly option.

Common RV toilet problems

RV toilets are prone to clogging and other plumbing issues. Fortunately, there are a few simple things you can do to help keep your toilet running smoothly:

  • Check the seals around the toilet for any leaks or damage.
  • Make sure that the sewer hoses are in good condition and free of blockages.
  • Empty the holding tank regularly and follow the manufacturer’s instructions for cleaning.
  • Avoid using harsh chemicals or abrasives when cleaning your toilet, as these can damage it.
