I fixed mine with a repair kit, specially made for this. the tanks are ABS. You might get by with some ABS glue and mesh.
A fresh water tank should be polypropylene that is only repaired by welding...?
ABS = holding tanks?
If it's black like mine it's ABS. The poly tanks are white/greenish.
They can be a lot of colors - mine poly tanks are black (slick to the touch).
If it is ABS - I repaired a cracked grey water holding tank made out of ABS:
- empty the cracked tank and allow to dry with the drain open
- fill a pint glass jar about 1/2 full with acetone
- allow new clean ABS plumbing fittings to dissolve over a day or two until the mixture in the jar is a brushable consistency paste that is not runny.
- stop drill both ends of the crack
- rough up the area around the crack a couple inches each side with coarse sandpaper or scuff pads
- wipe the area with a clean cloth dabbed in pure acetone
- cut some pieces of fiberglass window screen to cover the area of the crack
- apply some of your ABS paste with a brush to the crack area and embed the screen in the paste. Allow to cure.
- repeat applications of layers of screen and paste until you are happy with the strength needed in the area of the crack.
- clean the brush in acetone between coats
- store your mixture with an airtight lid if you want.
- I believe Home Depot in the US stocks various "grades" of ABS cement which contain more ABS - they are thicker - you may find some. They no sell in Alberta so I made my own ^
