IG pool with spa on the side. The motor seem to pull the water from the spa but dose not shoot out like it use to . Could this be the motor ? I have 2 intake at the bottom of the spa one that shoots the water from the heater works good but the other has not much suction but enough to dribble some water out. The blower works fine. When I turn the blower off you can feel little water flow coming out. Any help with matter!
