# In some cases, debris may pass through the strainer and clog the pump. Non-typical noise, vibration and/or reduced flow (despite cleaning/backwash) may be indicative of a clogged pump. If this is determined to be the case, ensure that the main pump motor disconnect is switched to the off position. A lock-out procedure may be required. Once the motor is safely disabled, reach into the pump and clear of all debris. | # In some cases, debris may pass through the strainer and clog the pump.

Observe the water in the strainer some period of time after the pump has resumed operation. The water level should be near the top, with minimal turbulence. If there is a significant amount of turbulence, air is likely being pulled in through the seal and entering the system. The screws must be further tightened. Otherwise, operation of the boiler and sensor probes may be negatively affected. | |||
During the cleaning process, the Chemtrol sensor probes may no longer be in contact with water. If possible, shut off the bypass line outflow valve prior to stopping the main pump motor. This will keep the sensors submerged. Otherwise, be sure to minimize the amount of time the sensors are out of water, as they may be damaged if allowed to dry out. | |||
