  1. Help me please!!!!!
    I have just bought another surflo pump 100psi on demand
    The problem is it will not cut out when I turn my tap off at the pole end
    Just keeps running making a funny noise and when I turn the tap back on the pressure built up is massive.
    Why won't it cut out like it should.
    Any help please
    Thanks

    Sounds like it needs a pressure switch
     
  3. I thought and was told by surflo that this would cut out if pressure built up?????
    The pump is on demand.
    Wasn't told about a pressure switch
    Where do I get this and is it easy to fit?
    Thanks

    Are you using it with a controller? If so, try calibrating it.

    I think they're standard on pumps but I've only ever bought one so don't know a lot about them.
    ve a look at the pictures on Window Cleaning Warehouse & see if it matches what you've got is all I can say.
     
  6. I am using a controller that is fitted in the van so it is a pain in the backside when I need to turn pump on or off.
    So I thought on demand would cut out if pressure built up when I turned the tap off at the pole.
    How do I calibrate it?
    Sorry if I sound thick but I'm pretty new to this I had my system fitted by K systems a year ago.

    Turn pump on and hold + and return together for about 3 seconds. That will bring up the setting your calibration is set to. Hit the + to higher the setting or the - to lower it.

    im sure some one else had this problem on a thread i read. I think you will need to adjust the pressure by the screw on the bottom of the pump
     
  9. My pump controller is just a box with a *** that turns there is no plus or minus buttons or digital display
    Guess I got sold the cheap one.
    Any ideas how to calibrate this ?
    Will look tomorrow for adjustment screw on pump.
