Couple of times today my water shuts off midstream. Walk back to the van to find the red light on. Switch the controller power supply off then on and carry on.
I'm guessing the pumps pressure switch has cut the pump? Any help appreciated.

Re calibrate?

[dazmond]

set the calibration higher.that should sort it dave!

[Dave Willis]

  I thought it would need to go lower?

Hi Dave the high flow setting means the pump is driving quite hard and creating a lot of pressure in the system. Also the calibration setting means the control is slow to dead end the pump.

The high system pressure is activating the pump pressure switch before the control can de the pump.
There may be a restriction or grit in the jet meaning pressure builds higher than expected.

What size id hose are you using? Are there any angle adapter?
Is the pressure switch on your pump adjustable? If yes turn it up a little

If there is no blockage and you like high flow. I would suggest turning calibration down slightly so that the control dead ends the pump rather than the pressure switch.

You may also need to turn flow down slightly. Oddly with fluid dynamics a smaller bore id  can act as a restriction in the system combine this with high flow and you create a lot of back pressure.

This back pressure can limit flow. Turning the flow setting and cal down slightly reduces the back pressure and can improve water flow through the hose.

Thanks Ian, that's pretty much what I thought was happening. I use microbore and subsequently never quite have enough flow. I also have to use barbed inserts in the pole hose which restricts the diameter of that. On top of all this the pole hose tends to twist and is permanently flattened at the point where it bends around the exit point of the pole base.
As I can't get any more flow by adjusting the clock past about position eight I guess I'm on maximum anyway and the pressure switch is just coming into play now and again. I guess I need to back the dial down a tad.
I have a Flowjet pump and have not played with the pressure switch - probably there is a set screw I can alter.

The micro bore its self although increasing back pressure is not a problem. I would agree with you the twisted hose at the top of the pole and the barb connectors are the likely source of the high pressure.
If you can open the end of the pole hose more it would make a difference. Probably the flow setting could be reduced as back pressure is also reduced.

Is the pressure switched wired in on the pump?

[Dave Willis]

Yep

As I an said then

I was having issues with mine. I never had PS wired in though

Ian i am hoping you and Oliver are going to be coming up with a special controller for my electric reels
