    Howdy Lads,

    I have a wee bit of an unusual problem. I have a positive shower pump that feeds two Showers with mixer taps. Shower pump went and I replaced with the exact same model of Grundfos STR-1.5 C.

    Sometimes when I open the valves on the Shower Mixer tap in the ensuite nothing happens. Same with the Main bathroom. Nothing happens, I have to resort to waving a magnet over the sensor to kickstart the pump.

    Any ideas what's causing this? Its going a long time.

    Is it.

    1. the Shower Mixer Tap.
    2. The Pump.
    3. An Airlock.


    Cheers
