I had a severe black tank leak, on a travel trailer that we used to have. Instead of buying a kit, I went to Lowes and bought a can of ABS cement and a short piece of ABS pipe. I used a reciprocating saw to make several cuts along the piece of pipe. I gathered all the cuttings and put them in an old cup. I poured some of the ABS cement in with the trimmings and stirred it up. I had already cleaned the crack as best as I could and scuffed the area around it with a wire brush. I put a couple pairs of disposable gloves on and spread my weld in and along the crack. That was 5 years ago and that tank has not leaked since.
this maybe the answer if it is ABS tank, I do read that some of the newer tanks may be polyethylene this procedure will not work with this cement mix. my freshwater(polyethylene) tank leaked and I paid someone to fix it with some type of adhesive, it lasted 1 year. then leaked, I took it out again and welded it up, I took an old big solder iron from my dad and silver soldered a stainless steel disc to the bottom and welded up the tank and it has been good for a couple of years now and has about 118 gallon of water in it right now. I now have fixed other plastic items and will melt in metal screen door wire for extra support. I have gotten pretty good at it not so pretty but strong.
