Hey Tim, yes it is safe to assume that since your tank is black it is made of ABS and ABS glue like the # A05-0303 will work. Are you installing a new valve or pipes?

we broke the flange on our fresh water tank where it is embedded into the tank, that uses that flange above how do I install a new one without dropping the tank. I want to saw out old one and put new one in but how do you tighten the back of it without dropping tank and reaching inside
