So as you know, i use four pencil jets on my brush and for me this works well.
Before i added the additional jets, i simply connected the brush as it came and straight onto the pole hose with a straight push fit connection.
When i added the extra jets i connected my pole hose with a Y Push fit connection.  Then jet hose with a plastic Y Fitting which went to 2 jets a piece.  The picture may explain better;


I have used it this way without major problems, though it does look untidy. It also becomes slightly difficult when navigating juliet balconies. But i managed ok and need a flow speed of 70 -80 (pure freedom digi controller) to get an even flow through all four jets.

My spare brush n pole that i use with the backpack also uses 4 jets and i connect them easily with a 4 way push fit split connector


This is lovely and tidy and a good flow from all the jets using a gardiner latest backpack. 
However i cannot source the same push fit for lager than 6mm jet hose. But then i came across a picture of someone eles four jet set up and i thought it was neat and tidy and so gave it a go;

This is my main brush. Using a T Equal split push fit fitting and then simply connect to 2 Y push fits.  This has not only tidied my brush up and made it easier for juliet balconies but i have a equal split of flow through all four jets on a lower flow rate as well.
So by simply changing how i have connected the jets i have improved it greatly.
Thought this might be useful or if not, what have you guys found that works best for you? That others may benefit from learning about

I use 4 or 6 jets on a brush and I just cannot see the logic of having two jets side by side so close. More sense to space them out evenly so no need to wiggle the brush from side to side to get water coverage on the scrub, saves work. Have a Reach it brush or two with 31 jets evenly spaced including up to the edge of brush in corners and only need one pass up and one pass down the glass, job done.
