I said 3" return line. Black ABS. Bulkheads vary. Amazon is decent, but activeaqua has the best prices on cheaper black ABS. Buy Threaded X Threaded and use 3" Male adapters on the ends of all your return line piping that connects between an all the totes and res. That way it's easy to take apart and clean after each use. The black oil filter wrench from harbor freight make tightening and untightening very simple. Then there's another website you can buy extra rubber gaskets to use on the bulkheads. Somehow I got the 2 I had to work and have never ever leaked but I remember it sucked to finally do it, cause the gasket kept squishing with tightening it. It needed to be thicker. I think wetting it during install would be smart. Silicone or sealant SHOULD NOT BE NEEDED If its done right.awesome, thanks
where did you buy your bulkheads?
so are we still using 2"abs as return lines still? or are you suggesting upping it to 3"?
