Can an uninstalled shower pump be tested?

[ShaunCorbs]

The outwards ones eg in your pic they have couplings on them

Can you activate the reed switch with a magnet on this pump? After standing idle for 5yrs I would expect the bearings to have a small "flat spot" which would increase the noise and vibration of the pump when installed and shorten the lfe span.

Thank you all very much for all your advice on my problem. As to this latest post I have a VERY powerful magnet, but do not know where the reed switch is located, nor what opening it would achieve. Please understand you are helping an idiot.
