You don't need this thing anyway - just go full flow.

i mean, when did anyone here actually VARY the water speed?

Exactly, never.

There's much more than flow rate to using a controller.

Yes its the flow master analoge controller I checked everything aswell and could find nothing wrong why would the pump run and then blow fuses if it was the diode. I suspect either the manufacturers or purefreedom are trying to get away with getting some more money out of us.

Ian IS the manufacturer

I suspect PF couldn't be arsed with you any more & blew it themselves!

Hi Liam in the 1st post it mentions that the problem is the diode has blown due to reverse polarity.

I have to work on the basis of the info given as I have not seen the control. If it is the reverse polarity diode it would only blow for one reason. The controls have a 12 month warranty form purchase so if the unit has failed due to a manufacture error we will repair it under the warranty.

This is why I ask if the unit has been returned so we can clarify what the issue is.

[Liam1990]

The unit was sent back because it kept blowing fuses no other reason.

[Ian Sheppard]

Ok Has the unit been returned to us At Spring?

The thread started with a comment about reverse polarity as well as fuses blowing. It is difficult to diagnose something I can not see.

There are a number of reason to cause a current surge and blow the fuse. As an example a pump with worn brushes in the motor would draw a higher current than a newer pump.

What size pump is being used in terms of PSI and current? also what flow rate and calibration was the control set at?

I suppose my comment could be taken two ways. I was serious, get out of jail free card for PF - just reverse the polarity & tell him it's his fault!!

[Ian Sheppard]

I would like to try understand why the unit was blowing fuses which is the initial issue. What is it that is causing the power surge? Hence my questions re the pump and control settings. 

It would also be useful to Know if the control is back with us and has been inspected by our engineer. This may have to wait until after the BH.

Exactly, never. flow is changed according to type of work - sometimes flow is changed 3 or 4 times during the day

[Liam1990]

The pump is a shurflo 100psi and was new with the controller the pressure cut off is set around half way. The unit was sent to pure freedom for the sole reason of fuses being blown one after the other. It was only today that we was told its our fault because the diote has blown and according to purefreedom the unit is at the manufacterer.

Paul do you know you don't have to return to tank you can just return to the inlet side of the pump instead? A tee on the outlet side, and a tee on the inlet side with a valve on the line is all that is needed.  I also don't believe in flow controllers, but I think a relay to protect the pump switch is a good investment.

That's exactly how I used to have mine set up, had it this way for 2 years. However, I would NEVER go back to it after using an electronic controller, just too many advantages with controllers.

There is nothing more simple than a proper controller, too many people use them for a day & decide they're no good because they don't understand how they work or know how to set them up correctly!

That's exactly why I don't supply them.  It is nearly impossible to trouble shoot a set up with a controller and a pump over the phone, should something go wrong with one of them.  I am also a great believer in running a pump on full power when cleaning windows, anything less than full and your wasting time.  My opinion, and I do relise that its not most people's.

You run your pump on full yet have spent your life creating devices to save water!!

There is only one way- electronic, anything else is constant compromise!!

[DG Cleaning]

What are the advantages of a controller other than saving water?
I know they are supposed to protect the pump but pressure switches are very cheap.

[Lee GLS]

I think there is an optimum spied that a pump should rind at before the water hits the window too hard and just splashes back off the glass, so a controller can save you water without it actually affect the rinsing speed.

[Peter Fogwill]

I know for a fact I am not wasting water having the pump on full blast. If I turn the pump down I am wasting time, and not saving water.  Remember I would only be using water when the brush is on the glass and cleaning.  I am not spraying water on the walls going from window to window, and not wasting water while putting the pole up and down.  A window takes a certain amount of water to clean, the faster that water is delivered the faster that window is clean and you can move on to the next one.

DG pressure switches are very cheap but you don't even have to replace them if you have a relay.  The relay is much meatier than the little flimsy pressure switches and last much longer.  They are also easier to replace as you just change over 4 spades with nothing to open.

Use less battery power, consistent pre-set flow regardless of height of pole, more accurate pressure cut off, press one button in the morning & that's it.
