OK, so I'll apologise straight away if this post offends anyone. We're all human so I'm hoping that more experienced caravanners (and motorhomers)may be able to help.

Just got back from my first trip of 2016 and because I had my dog with me I decided to use all the onboard 'facilities' rather than the shower block & toilets  -- my dog is a rescue and has separation anxiety.

On packing up obviously the watermaster needs emptying as does the Thetford holding tank for the chem toilet ....

Hence the main question :

Is there a 'trick' or can anyone share their experience on the best way to empty a tank which contains ..... erm ..... solids ? ! ?

Presumably others use their toilet for both 'options' (ie, not just a pee) so no doubt you have experience in getting the solid waste out of the tank !

Admittedly its not one of the more glamourous questions about caravanning, but hey, I struggled so I thought I'd ask

Not sure about the bio pods so you make your mind up on that one. My best tip is do not empty it on a full stomach, certainly for the first time.

Badgerboy,

It could be that the flush pump has seized or has failed in some way. This is most likely the case if this is your first trip in the 'van after a winter layup.

To check if it has seized turn off the mains charger so that you are using purely the leisure battery.

Switch on a 12volt light in the caravan

press the toilet flush button

If the 12 volt lamp dims slightly it tells you that current is being drawn by the pump even though it does not function.

If the pump is seized you can reach it by carefully prising up the panel around the blue flush button. It is held in place by mastic. Then there is a bracket to remove [4 screws I think] and then you can put you hand into the flush tank and raise the pump.

BTW in my van [2008] the handbook says that the full lamp is powered by a battery but in fact mine seems to be wired to the main caravan wiring ant on to the leisure battery. I have never seen that lamp lit as I always empty the cassette before it gets too full as I would find a full cassette too heavy to manage comfortably.
