Hello together, in order to prejudge the question of sense or nonsense, I just want to know if someone has already done it. Since apparently the multifunctional carrier of AL-KO was taken from the market, there is currently no solution known to me of a permanently connected waste water tank. So I thought accordingly to install a waste water tank firmly under the caravan floor and empty it by water taxi if necessary. I would have the possibility to install a tank sensor Is there any regulations to be observed here which I have to observe and has already done this and can provide reports? Greeting Manfred
