[VAC] Re: Fixing Black Water Holding Tank

["chyde" <brownhyde@xxxxxxxxxxxxxx>]

Joel,
If your tank is "plastic" it is most likely rotomolded polyethylene. Andy
could confirm this. Polyethylene is weldable. It can not be repaired with
anything other than the material it is made out of. Some polyethylene
welders are ultrasonic and some are glorified soldering irons with a hole in
the tip to allow polyethylene rods to be used as filler during the welding
process. You should check for plastic tank manufacturers in your area. These
places often do repair work. A lot a of bodyshops use this type of  welder to
repair bumper covers on modern cars. They may be able to help out as well.
Which ever route you take make sure the weld is more than just a mild
skinning over of the crack. If the weld is inferior it may hold in water for
a while but will probably split over time.
Good luck with it,
