Hello all,
I have a small leak in my graywater tank that has been patched by a PO
and is now leaking.
I wonder what the tank is made of? Is it ABS that will respond to a
fiberglass and ABS cement patch or is it something else ?
I didn't find much of relevance trying to search the archives. I have
just replaced the black tank and would rather patch the graywater one
instead of replacing it if that is a viable option.
Thanks !
Stu

Abs plastic will accept almost any kind of adhesive patch you just have to
make sure it is very clean and dry. The easiest patch I have come across
using readily available materials is abs glue and fiberglass mat. The mat
works way better than mesh.
