By using Inside Drops from RELINER/Duran in lift stations, pump life can be extended by preventing aerated influent from being directly drawn into the pumps. Their use can help dramatically reduce pump-related problems, as well as reduce general maintenance and odor complaints. The drop pipe should be extended below the low limit level and cut to follow the slope of the base fillet. If there is no fillet, cut the pipe at 45 degrees, one pipe diameter from the floor or fillet. This will create a diffuser by directing the flow back against the structure, thus de-aerating the influent. Do not direct the incoming flow towards the pumps. This simple arrangement is easy to maintain, as there is nothing to collect debris. It can be cleaned from above. 800/508-6001; www.reliner.com.
