Hot Water Booster Pump Problem

    Hi, I live in a single floor flat with a standard immersion heater hot water tank. As there is insufficient head between the water tank and the taps/shower the original plumber installed a single impeller hot water pump in order to drive them. The cold water is mains fed throughout. I replaced this pump a few years ago when the bearing wore out but I am now experiencing a different problem and was wondering whether anyone can point me in the right direction for trouble shooting.

    Normally when I turn on a hot water tap there is a slight delay and then the pump kicks in, what I am getting now is just a trickle and I can hear the pump humming slightly but it does not kick in. If I wait a while (anything from a minute up to an hour or more) and then try again it will work as normal. To my mind this seems to indicate a problem with the electronics controlling the motor but I am not experienced enough to be sure of this.

    I would like to avoid having to replace the entire pump as this will cost my landlord about £200 and when I can save him money it keeps my rent down and keeps him happy.

    I am a competent home electrician and a competent home plumber having done my own basic repairs for nearly forty years.

    There is no gas supply to the flat block so I do not have to worry about any issues relating to gas.

    Thanks in advance for any help that you can give.

    Eddie

    hi Eddie, there's not much you can do if a pumps not running, theres a sensor on the side that might need cleaning or a tap with a hammer but its unlikely, they're electronicly controlled by a PCB, here's one of my little video's i hope its informative and helps,
    tom,

    I know chippie but my dad had a bike and 8 miles is nothing to a northener, Bladley Wiggins lives in Wigan too i don't know if its just coincidence but he rides a bike and speaks northeren, albeit a bit posher :oops:

    Thanks Tom, turns out to be the capacitor - in contact with the manufacturer to see whether it is possible to get a replacement as the rest of the pump is OK and I hate waste.

    Think this thread has gone well off topic now :)

    hi Eddie, if its just the capacitor you should get one at maplins for a few bob, good luck,

    threads often take a tangent, its a fun forum as well as an informative one, I for one hope it stays that way, :)
