    hi all, my pump sometimes idles and trickles out for a few seconds and then goes back to the correct pressure, the controller says DE which means blockage i think, checked everywhere there and seams to be ok, any ideas ?

    also what should i charge for a average semi-detached driveway clean, and an average 3 bed semi gutter clean.
    thanks in advance Tom

    How long does it take for the pump to stop after turning the flow off?

    straight away when i turn it off, but when its on and flowing as it should its like it having a breather for 3 seconds and then goes back to correct flow again, probably pumps well for 7 seconds and then dribbles out for 3 then back for 7 and so on

    You need to calibrate your controller to increase the dead end.

    What kind of controller do you have? It sounds like you need to manually increase the dead end.

    Auto calibration doesn't always work.

    I don't think Tom understands what setting the calibration means.

    Its confusing as the Spring controllers are divided into 100 segments and as a Shurflo pump is 100 psi, users assume that when they switch the controller on, the figure shown is the psi.

    It isn't, its the speed you want the water to flow out of the brush head at. The pressure is calibrated either manually or automatically to work correctly at the water flow rate you want at the brush head.

    While you're here spruce, I have something similar going on. When I turn the tap to the off position on the pole and then turn it on, the water comes out slow for about 3 seconds and then comes out as it should and stays constant until I turn flow off and on again. I re-calibrated from 45 down to 35 and it's still the same.

    I think that will just be the dynamics of your set up. Once you turn the flow on, the water that is coming out at the brush head is the pressure in your system.

    Then it takes a few seconds for your pump to "pulse" and check if it's lost pressure, and your pump will start to work again.

    To instantly have your pump kick in when you turn your flow may not be possible.,it might always take 2-3 seconds.
