    I don't understand, if there is no hole in the suction pipe, and the suction pipe is submerged into the liquid, then its IMPOSABLE to suck air, are you sure its sucking at all, or perhaps you have the pipes wrong way round, suction pipe over tank and dilivery pipe into liquid......

    you see...cannot do mistake cos' the outlet pipe have non-return valve...i think may be the motor life finished...only turning but can't suck the liquid up....or do you have other way to test the motor.....
