Not sure if someone has told you but you can get the same soil pipe Health uses in his tubes in the states. It is call SDR-35, it is all gasketed not bad prices if you call around to you local plumbers suppy houses etc. I am gearing up to build 1 myself so have researched a bit lol They should all the fittings he uses they will just be a light blue.
Hope I helped a little.
