Repair of Black & Grey Water H2O tanks. . . .

I have repaired several cracks etc on these tanks over the years. It is not difficult. Buy some fiberglass cloth, a can of MEK, and large can of ABS cement. All of the items can be found at Lowes type stores. MEK and fiberglass cloth in the paint dept and ABS cement in the plumbing dept. Clean the damaged area with the MEK. Cut your cloth to cover the area with about a 1 to 2 " overlap. Spread a good layer of cement over the area, lay the cloth over the area and work the cloth well into the cement. Next cover the cloth with a new layer of cement and smooth. After the cement has dried for a few hours,repeat the process with a second layer of cloth and cement. Cut the second layer of cloth larger than the first. Working the cloth and cement where the pipe joins the tank will take a little work and will be messy. The repair may not be pretty but will be strong. I have never had one of the repairs crack out again. The tanks are ABS material and you have more working time with the ABS cement than with a two part cement. If you need more info get back on the forum.
