Is this pump a 2 wire (or new 3 wire) or a 3 wire (or new 4 wire) pump? If it's a 3 wire it must have a control box in the line. For the pumps safety it really needs a pressure switch and at least a small tank or a Pside-kick installed. If there is no tank and pressure switch you must be sure that there is no way to cut the water off anytime the pump is running otherwise you will burn out the pump. My suggestion would be to get the pump working properly because without it I doubt that you will need the drains!
