NOTICE BY SPECK PUMPS: Before turning the pump on after a long period of disuse (e.g. winter), check to make sure that it can be moved easily. To do this, rotate the motor shaft lightly with the help of a screwdriver. Should the motor stick at all, this will loosen it. Should the pump still remain tight or an unusual noise become audible, have the pump examined by a trained professional
