We have a campervan auto-trail v-line 670s 2021 

does anyone have a solution for water draining out immediately after filling the fresh water tank?

when I fill the freshwater tank ,it drains out of two blue pipes under the van as if syphoning 

I tried to time it so I stops the filling just as the first drop starts coming out 

this means we are only ever 50-25% full as is limiting our off camp site activities 

thanks

    Is the tank drain tap closed?

    Other than that, check your handbook and/or call your dealer.

    TW raises Pt1.

    Pt 2 have you fully closed the drain off for the Truma heater and pushed the button in?The yellow turnlever should be across the line lay of the piping and the dump button below it should be fully pressed back in.

    After drain off for Winter layup such things can be forgotten....

    Otherwise back to the dealer😏.

    As TW says. Our MH is a Hymer, but the drain on the fresh water has two positions. Unless it is fully closed the tank will only partially fill and then start venting.
