How often do you empty a caravan toilet?

In this short guide, we will explain: How often do you empty a caravan toilet? We will tell you how to empty, clean, disinfect and properly use a caravan toilet. 

How often do you empty a caravan toilet?

A caravan toilet should be emptied at least every two days if you want to prevent bad odours or overspills.

The maintenance of a caravan toilet is essential to avoid the gradual deterioration of the equipment. To do this, you must not only make sure to use a specific product (blue or pink product) for the degradation of faeces and the disinfection of the toilets but also to empty the tank so as to keep it clean and ready to be used again.

Here’s how to empty a caravan toilet, step-by-step:

To empty a chemical caravan toilet, the first precaution to be taken is to identify the tank to be emptied. Typically, a chemical toilet is made up of two tanks: one containing water for flushing and the other for receiving materials to be dissolved by the chemicals.  In this case, the correct method is to dismantle the waste tank and locate a suitable site to empty your chemical toilet.

  1. Position the toilet vertically.
  2. Take out the drain tap (tilt it slightly)
  3.  Open the drain valve cover 
  4. Tilt the tank, orient the drain cock towards the side edge of the drain tank. Do not aim directly into the water to avoid splashing. Aim carefully for the edge and you should be fine.
  5. As soon as the water flows out, press the button, removing the vacuum effect during the flow.

Note: If you have access to the city’s wastewater network, you can plug a large funnel into the sewer so that the contents of the organic waste tank can be more easily drained.

Remember, it is not allowed to empty the organics tank anywhere.

Where to empty a caravan toilet?

When you are camping or on the road, it helps to educate yourself so you don’t commit bad acts like dumping in the countryside. The law prohibits the dumping of chemicals into nature and obliges all citizens to adopt environmentally friendly behaviour.

Camping or service areas are authorized places to empty a chemical toilet. These areas are known to accommodate specific spaces for this type of activity.

In addition, you can also proceed without consequence to emptying your chemical toilet into a wastewater network.

However, it is not recommended to empty your chemical toilet in a toilet connected to a septic tank. The chemical elements that result from the transformation of faeces are not compatible with the functioning of a pit because they can destroy the bacteria essential for it.

Where to empty the caravan grey water tank?

Gray water is water that comes from showers and sinks. The grey water tank has a capacity of approximately 100 litres and is located under the floor of the motorhome. To evacuate this used water, all you have to do is open the taps, valves or hatches which flow directly under the motorhome.

The service areas have a concrete emptying area equipped with an escape hatch (the size of a manhole cover) on which you will have to position your motorhome. An operation that may require a little skill during the first oil changes.

Allow ten minutes to evacuate the greywater. During this time, you can begin to detach your removable cassette from the black water.

Where to empty the caravan black water tank?

Blackwater is water that comes only from chemical toilets. They are stored in an extractable cassette with a capacity of 10 to 25 litres (to be emptied every two to three days), which is located outside the motorhome. For ease of transport, some are equipped with a handle and small wheels. 

Then simply take the cassette and empty it using its pouring spout into the receptacle provided for this purpose. Provide gloves because you will need to lift the cover. Use two litres of water and a mixture that neutralizes bad odours to rinse your cassette.

If you have not found an area, you can always use the sanitary facilities of the campsite or a gas station provided that your chemical toilets do not contain any chemical product. Make sure you clean everything up when you leave!

Drain without polluting! No emptying of black water or greywater should be carried out on public roads, in rainwater outlets or in nature. Even if you use biodegradable products (dishwashing liquid, shampoo …) which spill into your greywater, you must not empty them on the road while driving or in the middle of nature! 

Out of good citizenship, you must be prohibited from emptying anywhere in disregard of the essential rules of cleanliness and hygiene and out of respect for the municipalities you pass through.

Before leaving the service area, remember to close your valves so that the water does not continue to drain while driving.

How to properly clean a caravan toilet tank?

All or most of us know how to clean a toilet depending on the dirt it has and how it is presented. But knowing how to clean the caravan toilet tank is something very important that we should not leave behind, so today we will teach you how to do it.

To clean your caravan toilet tank you will need:

  • A bottle of white vinegar
  • Rubber gloves
  • A cleaning brush
  • Liquid cleaner or detergent

The cleaning process (step-by-step):

  1. The first thing we will do to clean the toilet tank is put on rubber gloves. Cleaners are full of chemicals and vinegar is very corrosive and harmful in direct contact with skin, so it is best to wear rubber gloves to avoid hurting the skin on your hands or getting dirty while cleaning the toilet tank.
  1. Remove the cap from the tank and pour all of the white vinegar inside. The vinegar will eliminate odours, disinfect, and kill insects, bacteria, and microbes that may be inside the water tank. It is convenient for you to carve the tank with the brush while the vinegar is inside since this will be more, but do not empty it yet.
  1. Let the vinegar sit in the tank for 50 minutes to 1 hour. After the time has elapsed, pull the lever on the toilet to empty the tank. It is a good idea to take advantage of the vinegar that falls from the tank to also scrub the toilet and thus remove scales and stains that may be on it.
  1. Turn on the faucet to get water into the toilet tank again, but don’t fill it, just add enough water to start scrubbing it. Time to use the cleanser and brush. Spray the cleaner on the brush. If you don’t have spray cleaner, then mix ½ cup of water for 2 tablespoons of detergent and add a tablespoon of vinegar or bleach to the formula, dissolve it well, and put it in a spray bottle. 
  1. With this formula, moisten the brush and the walls of the tank, carve it very well so that the toilet tank is better cleaned.
  1. Carve everywhere and make sure that all the soap goes down to where the water is. After this, with a gourd or with the same brush, take the water to the walls so that the soap comes down. Rinse again with plain water and empty the tank.
  1. Open the tank tap and let it charge again, let it fill up. If you see it necessary, place a deodorant and cleaning tablet inside the toilet tank so that the next cleaning is less frequent and more effective.

Now you know how to clean a toilet tank easily and effectively without needing a cleaning arsenal!

Final advice

When cleaning your caravan toilet bowl, remember to clean and disinfect the black water tank as well! The tanks or cassettes that collect the sewage have a rotating tube through which they are discharged into the corresponding drain, and which must be connected to a septic tank or the sewer. For cleaning, it is advisable to have a running water tap nearby, different from the clean water tap.
