  Kathleen RichAug 2, 2025
  If your Bell and Gossett Water Pump has inadequate circulation, consider these steps: First, vent the system if it is air-bound. Second, check for any clogs in the impeller or piping and remove any obstructions. Third, if the impeller is damaged, replace the pump. Fourth, if the pump is too small, replace it if it is single speed, or switch to a higher setting if it is a three-speed pump. Fifth, vent the pump casing if the pump is partially air-bound. Finally, check the wiring and voltage if the motor speed is improper.

Why is my Bell and Gossett NRF-25 making noise?
- C
  Christopher GibsonAug 12, 2025
  Pump or system noise in your Bell and Gossett Water Pump can stem from a few issues. It could be due to entrained air, in which case you should vent the system. Pump cavitation might be the problem, requiring you to lower the pump, raise pressure, or relocate it. Excessive water velocity can also cause noise; consider installing balancing cocks or parallel piping. Lastly, pipe vibration can be a factor, so ensure adequate pipe support.

  Premature failure of components in your Bell and Gossett Water Pump can be caused by several factors. These include using an improper pump size or type (in which case you should replace it), an improper pump location (relocate the pump), excessive water treatment (check the manufacturer’s instructions), the pump operating close to or beyond the end point of curve (balance the system), or excessive piping load (provide proper pipe support).
