[VAC] Re: Black Water Tank Repair

["Dr. Gerald N. Johnson, electrical engineer" <geraldj@xxxxxxxx>]

The best tank making plastics, generally polyethylene, don't allow
adhesives or resins to stick to them. They were originally either molded
or heat welded. Heat welding can be used to repair them, but not by me.
It involves hot air and filler rod, precisely the same procedure as gas
torch welding but at a lower temperature.
