    morning all,
    i have a shower pump which is running on and pulsing, only started after i had to turn off mains water, I've bled it several time, taken off inlet hoses and check float switches, no joy, funny thing as soon as u power off resets straight away and doesn't pulse, any ideas would be appreciated, thanks B

    pipes good, no change from original setup, only came into it since water turned off, suppose air seems to obvious cause but cant bleed it anymore ! thanks

    My guess is the little detector circuit in it is packing up or else the sensor. I havn't had a good gawk at that circuit but it could be worth bypassing to see if it runs OK. Else it is a water flow issue
