Knowing how to empty a motorhome cassette toilet is going to be an important bit of touring know-how. After all, even if you’re staying at a campsite, you may not fancy a trek to the toilet block in the middle of the night.
Our expert, Peter Rosenthal, advises that as long as you empty your cassette regularly and use the correct dose of the best motorhome toilet chemical, you should be able to avoid it smelling.
You’ll know when it’s time to empty it as the red ‘full’ light will come on. A word of advice from us – one motorhome mistake you will want to avoid dealing with is overflows, so when you see the red light, empty it.
The good news for those who are wondering about how to empty a motorhome cassette toilet is it’s relatively straightforward to do, as this guide explains.
First things first – make sure the blade is closed, if the cassette is fitted to the toilet, by moving the blade handle. The cassette toilet should generally slide out quite easily, with a push-down catch releasing it – if it doesn’t, don’t force it. The most common reason will be the toilet blade still being open, locking the cassette in place.
After closing the blade, head outside to the cassette locker, unlock it and open the hatch. To release the cassette, you generally need to nip yellow or orange handles together with the grey grip.
The orange grip will generally double up as an extending handle, allowing you to wheel or carry it to the designated waste disposal point. Never empty it anywhere but a dedicated facility – it’s not only unhygienic and bad for the environment, but also antisocial too.
Once you’re at the disposal point, retract the handle, twist the empty/fill nozzle and take the cap off. Another mistake to avoid – don’t leave the cap near the disposal point, otherwise, you could find yourself having to fish it out.
Now press the orange vacuum release button and empty the contents into the disposal point. The button lets air in, so should minimise any splashing.
After emptying the cassette, be sure to give it a thorough rinse, using clean water to freshen it up until it has next to no odour.
Then, before replacing it, reach for your blue or green toilet chemical and add a dose with the required amount of water, before popping the cassette back into place in the locker. Make sure you know how to choose the correct toilet chemicals for your motorhome loo to help here.
