Just saw this on YouTube with Ian Sheppard advising on best settings for Pump Controller, very interesting.

Probably the best test of all is brush on glass cleaning windows when your working. You find your sweet spot for everyday cleaning and this is your go to flow setting. Lot's of water isn't always best an example is poorly maintained sash windows where you need to keep water contained to avoid it leeching out dirt once you've finished and causing spotting.
Thanks for posting though interesting viewing.

Interesting video. Thanks.
And I think we all know Ian is one very clever & helpful guy.
Nice to be able to put a face to the name also.

I think the main point that has been missed by theses boffins is if you want more flow rate increase your jet size from 2 mm to 3 mm and reduce your controller number and get more flow . Simple really there is no need to make it complicated

I wouldn't use 6mm microbore hose with any reach-it rinse brushes for the simple fact it wont produce enough water flow at the brush head unless the flow controller is turned up nearly to maximum which in turn would drain the battery in no time.
I use 12/10mm flat hose on a hosereel coupled to 10/8mm pole hose which is ample flow and pressure for rinse bars, even in winter on medium settings which doesn't draw to many amps off of batteries.
Microbore and 5mm polehose is fine if using pencil jets but not with rinse bars unless everything is on full flow.

So just put it on full flow then
Absoloute nonesense about draining battery. I used to have 2 pumps running all day full flow with nothing more than a split charge relay. Dont even need to bench charge battery

Yep, 3mm jets make all the difference, I love em’

They give an illusion of the flow rate forcing water through a smaller jet,listen to what the bloke says it gets to a point that you won’t get anymore water through the hose lol.
Do the bucket test with different sized jets you’ll end up with the same amount of water.

Did that years ago and can assure you 3 mm will give more volume of water than 2 mm

You get fatter water for better rinsing, 2mm jets fire the water at the window and it bounces off, 3mm gives slightly more flow and fatter, heavier stream down the glass. Less splash back.

I use the black standard pencil jets from Gardiner not the smaller blue ones I used to have my controller flat out on 99,after calibrating the pump properly I’m getting the same flow at 70 and it’s running half as hot as it was.

The black jets are 2 mm and at 70 instead of 99 your water will be hotter not half the temperature . As you will be using less water so it’s going through the heat exchangers slower thus getting hotter

Yeah when I can get a new fuse holder sent to me so I can turn it back on again lol,we’ve been getting away with it last couple of months tbh on regular cleans.
-
I have mine on 50 or 60(microbore and 2mm pencil jets).plenty of flow...
It's interesting that no more water is being used past 70 on the flow controller

Fluid dynamics - you can only force a certain amount of water though a small hole

I am very grateful to Dave and Sam Peden for the opportunity to make the Video. It was very useful to do these tests on WFP Van system that is in use every day

Hi Ian for the new V16 to work as a split charger what do you need just a couple of wires fed through from the vehicle battery,I also saw Dan Smithson visited you’re premises was that the one in Crowborough.

Certainly true with an Ionics diesel heater.
We have mixer valves on our heat exchangers that keep the hot water at a fairly constant temperature. So in theory, slowing the flow down will just reduce the temperature at the brush head as the water has more time to cool down in the hose.

Thank you for the video, very informative and I actually enjoy that geeky side of stuff!
Personally, I use about 30m of Gardiners 5mm reinforced pole hose on my main reel (the other 60m is microbore), because I had tennis elbow (rather painful) and the 30m is really easy to pull and move around.
So technically the smaller diameter of the 30m pole hose does restrict the volume of water.
However, I have just fitted a new sureflow pump which re-calibrated to 35. (I know, this sounds very low) but this gives me about 7-8 feet jet of water using 2mm jets and a Gardiners extreme sill brush, which I think is a fairly decent flow.
This is just my opinion, but I like a good amount of water under the brush when I'm scrubbing; so I'm sort of agitating and 'partly' rinsing at the same time. I find I can achieve this 'good amount of water', whether it's pencil jets, fan jets (which I sometimes use) or Xline rinse bar (which I sometimes use).
So, for me, providing I have a good amount of water under the brush, for scrubbing, I don't mind which method I use. Having said that, I do prefer the standard 2mm jets. For large areas of glass the longer bristles and rinse bar of the Xline brush is brilliant.
So the final rinse is 'a bit of a gesture', ok I use that term rather badly, but hopefully most of my work is done with the scrubbing and same time rinse. For me the final rinse is a rather quick affair.
And, in this weather, it's easy to check your work.
Thanks again for the video.

im using 2mm jets but like my flow set at 53 but my heater wont cut in till its set at 67 i find it to powerfull as you get water going were you dont want it up vents ect im guna try 3mm jets next
