Waste Tank

[Chris Gill]

Learn something new every day. Just found an entry to the waste tank from the garage in my Geist Phantom. By it there is a wire leading in to the tank through something with a blue top. Don't want to fiddle just yet, but would I be right in thinking this might be a heater, which presumably would turn on automatically?

...it might be, but, unless you can see one elsewhere, I'd be more inclined to think it is the (waste) water level probe.

Thanks Robin, just had a rethink on this and am inclined to agree

It’s definitely a tank level sensor.

 

These two adverts relate to the sensor that’s fitted to Burstner motorhomes

The asking-prices differ significantly and the 2nd advert refers to the item as a “fresh water tank sensor”. It’s certainly the case that this type of ‘multi-probe’ sensor is commonly fitted to motorhome fresh-water tanks, but waste-water tanks usually have a cruder arrangement. There’s no compelling reason why Geist should not have chosen to use this type of sensor for a waste-water tank though...

 

When a tank heater (example here)

is fitted, it will normally be installed low down on an external waste-water tank (and occasionally on an external fresh-water tank) with the heating element protruding horizontally into the tank’s interior through the tank’s sidewall. Alternatively a heating ‘pad’ can be stuck to the underside of the tank.
