If your Pentair Water Pump isn't delivering water to its full capacity, it could be due to the following reasons. If steel piping is used, it may be corroded or limed, causing excess friction; replace it with plastic pipe where possible, or with new steel pipe. The piping might also be too small; use larger piping.
How to troubleshoot a Pentair AERMOTOR CT35 Water Pump that will not start?
If your Pentair Water Pump motor won't run, start by ensuring the disconnect switch is on. Check for a blown fuse or tripped circuit breaker and replace or reset it. If these steps don't work, the starting switch may be defective and need replacement. Also, inspect the wires at the motor for looseness, disconnections, or incorrect wiring; refer to the wiring instructions and tighten all connections after disconnecting power. The pressure switch contacts might be dirty; disconnect power and file them with an emery board or nail file.
Why does my Pentair AERMOTOR CT35 Water Pump motor overheat and shut down?
If the motor of your Pentair Water Pump runs hot and the overload protection activates, it could be due to several reasons. First, ensure the motor is wired correctly by referring to the wiring instructions. Low voltage could also be the problem; check with your power company and consider installing heavier wiring if the current wire size is too small. Finally, the pump might be cycling too frequently; consult the section on too frequent cycling for solutions.
Why am I getting air spurts from my Pentair AERMOTOR CT35 Water Pump?
If you're experiencing air spurts from your faucets when using your Pentair Water Pump, it may be picking up prime; once it has, it should pump solid water without air. The well could also be gaseous; consult the factory about installing a sleeve in the well. Another possibility is intermittent over-pumping of the well, where the water is drawn down below the foot valve; lower the foot valve if possible, or restrict the pump discharge.
How to fix a noisy Pentair AERMOTOR CT35 Water Pump?
If you're experiencing mechanical or noise problems with your Pentair Water Pump, it could be due to a bent shaft and/or damaged bearings; take the motor to an authorized motor repair shop. Alternatively, the suction and/or discharge piping may not be properly supported and anchored; ensure all piping is supported to relieve strain on the pump assembly.
