    Pumps and thermal cut outs

    @Itsmoked interesting idea. not sure whether practical for me: the pump controller is secured to a cross strut about 100cm from the top of the well. and it's mounted on the vertical (making the button accessible only from the front). I also don't relish the idea of drilling this manhole...

    Pumps and thermal cut outs

    yes - possible that I could sense whether there is a connection to the relay and then implement my own relay providing power to the pump. But that bypasses the cut-out device, rather than allows a reset. Big difference. the well will partially refill continuously. so if I fire the pump every...

    Pumps and thermal cut outs

    @LittleInch they are nothing special, no. I am on my fourth in fifteen years (they don't survive the winter very well). essentially they are low pressure switches. you turn a tap on, the machine senses a pressure drop and kick starts the well pump motor. I know that I have the box on top...

    Pumps and thermal cut outs

    Artisi it doesn't matter what mechanism causes the trip, sod's law dictates that it will need resetting from time to time and almost certainly when I am not around to do it. So there is still a paramount need for a remote reset. @rotw The diameter of the borehole is 100cm. I don't recall...

    Pumps and thermal cut outs

    thanks. that would be my response to a typical electronics question too. However these well pump tops are so common that I felt sure that someone in this forum would know about them. They are sold everywhere in France so I assume that is the case elsewhere. good point on the thermal cut...

    Pumps and thermal cut outs

    Thanks. And whilst I appreciate the practicality of your post (and i already do something similar) it is not an answer to my question. Which relates to remote resets of thermal cut outs.

    Pumps and thermal cut outs

    yes - it is low water. the water table drops radically when the farmers over water during july and august. i'm happy for the pump to cut out. but i want to be able to reset it sensibly, without taking the man-hole cover off each time. and yes, the reset button on the pump controller...

    Pumps and thermal cut outs

    Hi i have a well pump about 23m down a well. It's under a quarter ton manhole cover ... at certain times of year the pump cuts out, needing a manual reset. the reset is on the low pressure head at the top of the well - but under the manhole cover. there is no scope (budget wise) for...
