Called a friend of mine in Independence after I remembered he had a to replace an air pump for his septic tank a few months back. He couldn't recall the name of it, but got the pump from Desoto Concrete Products here in Olive Branch. Quick search and it will give you their number. Not sure what brand they carry or service, but they may can point you in the right direction. Also, found this on the web, may give this number a call on their site.
