I am presently trying to find information regarding the design of a manifold system for underground storage tanks. Specifically the need to maintain constant vacuum to keep a manifold bar primed. This is usually accomplished by the suction from the pumping unit, however in this case due to poor design(improper equipment)it is being suggested that the bar be 'closed' and the tank(s) be pressurized to charge the line and hope the liquid levels never fall below the product lines in the tanks. This would obviously cause the need to repeat the process when needed. This , in my opinion, is an unacceptable poor design and is being rejected at the moment. Question: Does anyone know of technical or other recommended practices for this method. Any info wouldbe greatly appreciated. Mkeith1650@email@example.com
