I am currently adding new tanks to the GT and as usual flying blind with no reference material. The new toilet mounts over a toilet flange and the new ABS tank needs a solid weld or bulkhead fitting to handle the compression and shock from being a roadworthy install.
I sourced a 3" ABS recessed tank fitting but am concerned that the ABS cement is not enough to hold this bad boy in place. Should I weld it? Why isn't this item made like a bulkhead fitting that clamps in place? The flange is bumpy and has a stippled pattern, does this indicate that it should be sealed in a certain way?
I'm no plumber, but know better than to trust some spray on ABS cement over a weld when it comes to a solid connection where I want keep my solid waste contained.
