Thought I was missing something here...but this methodology went the way of the 2lb cell phone...much has been learned/improved since the 80's as noted above. I would recommend investigating what many others are doing with their sumps on this board, and others boards, and I am sure you will find this practice is not used any longer. Not saying you can not achieve your goals using them, but I would research further. Cheers.
