I know in a previous thread (quoted below) you guys recommend the Oatey brand PVC cement to assemble the drain pipes. However (just to be sure and so I've heard it from you guys) can you advise as to the equivalent WeldOn brand cement to use on your line?
No. That's grey colored for electric conduit.
