To begin, our "onboard" fresh water system consists of two, 5 gallon plastic cube type water jugs from wallyworld. I modified the lids and they work ok, giving us 10 gallons feeding into a pressure pump.
With that said, when I did my RV junk yard scavenge almost two years ago, I found a 38 gallon, standard RV, fresh water tank and got it for $10. It has been sitting on a shelf, fully cleaned and sealed, since I got it. And that drives me crazy. Here is a perfectly good, but admittedly very large water tank and it does nothing but sit on a shelf. So my thought is to modify it, to cut it down to say, 10 gallons or maybe a bit more. Its circumference measurement fits perfectly in the space where I presently keep the two water jugs, it is just really long.
So, the idea is to cut it down, then to seal the end up to make it a smaller tank. Does anyone know the proper way to "weld" one of those white plastic (I assume poly) water tanks? Or am I asking for trouble?
