Why motor seems noisy. What do I do?

Make sure all the baskets are cleaned out. If there is too much debris in the baskets it could restrict the water flow and cause the pump to cavitate and thus make noise. Make sure that your pump O-ring has been lubricated. If not, this could allow air into the system and cause the pump to become noisy. Make sure the water level is mid-point on the skimmer. A water level that is too low could cause the skimmer to suck in air and cause the pump to make noise. Make sure all your equipment control valves are set properly.
