I recently replaced our twin impeller shower pump and being very concious of the fact that these mustn't be allowed to run dry I made quite sure that the power was turned off throughout the process.
However when I tested the new pump and found the hot water flow to the shower be rather low I thought that I ought to check that the new rubber washers on inlet and outlet to the pump were seated properly and weren't blocking the flexible hoses.
I therefore turned the water off and started to undo the the hose connection to the pump but forgot to turn the power off again. As a result the pump started to run for a very few seconds as the water pressure dropped before I was able to fully tighten the connection again.
Whilst the pump now seems to be performing as it should I would be grateful to know if I could have caused it any damage.
Many thanks, GSD
