ive just got a bigger van and was going to put a 500ltr tank in it but i have already a 250ltr upright tank in my old van, and was wondering about getting another to fix together to make 500ltrs. i am going to join the two tanks via the outlets and have a "y " garden hose branch in between.
hopefully the two tanks will fill and empty together through the joined outlets, has anyone else done this, or have any advise on how to set it up.
thanks steven
