1999 Benimar Europe 6000 ST Fresh water tank

[Clankie]

Good afternoon,
I am assisting my son with a recent purchase 1999 Benimar.
I know this is an elderly MH but can anyone assist me with the explanation in the owners manual, regarding filling to 50litres when travelling and 125litres when on site. I can’t find an overflow valve which I assume could be opened to discharge to waste when the contents reached 50litres, then closing to fill to capacity. I’ve found a valve inside the MH between the outside wall and the tank located at bottom, I’m assuming this to be the drain. When I opened it, water did discharge to the road. I’ve opened the tank lid and taken photos of a float system which must be the contents gauge. Also I can’t find a drain valve under the van.
Any comments would be gratefully received.

Mine although a bit newer but might may use the same system,it has a short length of water pipe with a push on stop end next to the main fresh water drain. You just pull the stop end off and it drains or fills to 30 lts . I hope this is some help

Thank you, I’ll have a look when we get the van back
