salamander shower pump problems

Salamander shower pumps are known for their efficiency, but like any mechanical device, they can experience problems. In this article, we explore common issues with Salamander shower pumps, particularly the CT75X 250w model, and discuss potential solutions.

Identifying the Problem

  1. Symptoms:
    • Pump fails to start despite various attempts.
    • A trickle at the shower head, indicating insufficient water pressure.
    • Previous issues with air locks due to the pipe work layout.
  2. Attempts at Resolution:
    • Bypassing pump switches to purge the system.
    • Replacing the capacitor.
    • Checking for voltage supply with a multimeter.

Potential Causes and Solutions

  1. Air Locks in Pipework:
    • Air locks can significantly affect the pump’s ability to function.
    • Solutions include reconfiguring pipe runs to eliminate high points where air can be trapped or using a wet/dry vac to start water movement.
  2. Pump Failure:
    • If bypassing the switch does not start the pump, it may have burnt out or seized.
    • Manually spinning the impeller can indicate if the pump is seized.
    • A burnt-out pump will require replacement.
  3. Negative Head Pump:
    • Considering the complexity of the pipework, a negative head pump might be more suitable.
    • This type of pump is designed to work in situations where the water supply level is not sufficiently above the pump.
  4. Pipe Run Design:
    • A challenging pipe run design, with arcs and right angles, can contribute to airlock issues.
    • Using nail-in pipe clips to secure and flatten pipes in the loft may help minimize airlocks.

Conclusion

The key to resolving issues with a Salamander shower pump often lies in understanding the specific installation and any unique challenges it presents. Air locks due to complex pipework are a common issue that can impede pump function. When a pump fails to start despite various troubleshooting efforts, it may indicate a more significant problem, such as pump failure or seizing. In such cases, pump replacement may be necessary.

For rental properties, where extensive modification is not an option, understanding the existing installation and adapting to its constraints is crucial. When considering a new pump, factors like the complexity of the installation, the height of water supply relative to the pump, and the overall design of the plumbing system should guide the choice of the pump. Regular maintenance and attention to potential problem areas can help ensure the long-term functionality of the pump.
