i have a rio 3600 or somethign pump.. and basically it stopped working... it still makes the motor soudn that its working.. but its not pushing out any of the water. whats wrong...anyobdy know how to fix it?
not to familiar with that pump model, but check to see if the impeller is dirty. Try taking it out and cleaning it.... put it back in and see what happens. Not exactly a expert opinion although I have done it many times before when filters were going that and they worked after.
