Mike- Try "burping" the system. That is, disconnect the outflow hose from the pump, turn on the unit and then reconnect the outflow hose to the pump. worth a try. Guru told me that some pumps/installations require burping every time the strainer is cleaned out.. Bob siegel annapolis

My one-pump-for-5-A/Cs system gets an airlock in the pump impeller over time...apparently all the Hatt LRCs have this problem. Your impeller should have a screw on the top to allow the pump to prime (AKA burp). Remove screw and allow pump to run until you get a VERY strong spray from the hole. Should solve it...(hope its that easy!) Bob ________________ Robert Calhoun Smith Jr M/V MARY KATHRYN Hatteras 58 LRC South River Annapolis, MD, USA
