I am dealing with a boss that has no mechanical background and a coworker that considers himself to a mechanical God which is leading me to have some concerns about a piping system that they have installed. It consists of some fluid tanks that have overflow drainage leading to a pipe that runs along the floor which finally comes to a vertical rise of about 6 inches, then proceeds to drain to a pit in the floor. I suspect that there will be an issue at the 6 inch vertical lift due to the fact that there is no head pressure in the system. I have a hunch that the overflows will start to back up and not flow freely because of this vertical lift in the pipe which will be detrimental to the proper fluid exchange needed with respect to these tanks. I believe there will be a serious back up or serious flow restriction unless we somehow remove the 6 inch lift or install a booster pump. All input is welcome!!!
