How to Fill & Empty the Flush Tank

This is a topic raised many times on Facebook and other forums, especially by newcomers to Camping, Caravanning and Motorhomes. How do you fill the Flush Tank and how much fluid do you need to add.

Thetford website states that the Flush Tank has a capacity of 15L

Here I show you what I do on our Conway Crusader Folding Camper and I'm sure it's not much different on other units.

Over the years I've tried many of the different toilet chemicals and now only use the Proshot range from Qualkem. Both the Blue and Pink fluids have a lovely Cherry Fresh fragrance which we think smells more like Bubble Gum. Now use their ECO Green liquid which can be used in both tanks.

Hope you enjoy the video and please click LIKE and also subscribe to the channel.

Thank you! 1st video in 20 that I've searched that covered how to fill/empty the flush tank.

Very helpful, thank you. First time Pennine owner, very confused as to how to fill the flush until your video explained all!

I've never had a toilet with a flush tank before so this video was very helpful, thank you.

Thank you so much for this video and information! I was desperately trying to drain our holding tank in anticipation of an out of the ordinary cold snap, and couldn’t find the relevant information in manuals or other searches. Saved us from a burst tank/plumbing!

Super clear instructions!! Thank you so much!

I have a blue and a pink bottle of fluid. Instructions for both are in German (Dethleffs!). Are they both the same thing?

Very good. A couple of observations on the top of toilet cassette there should be a small green funnel that fits on top of flush tank filler that makes it easier to fill also capacity us 15 litres to fill .
