Thinking of buying supreme medium hybrid 35cm brush and not sure what would be the best jet option. My reel hose is 8mm.
I borrowed a Gardiner 45cm brush with 4 x 1.4mm jets from a friend of mine. The 1.4 jets are about 1/2 the size of 2mm jets.
I found my current flow controller setting (4 to 5 on a Varistream) gave a nice rinse. This is the same setting I use on my standard brushes with 2mm jets. I would imagine the smaller brush will give a better coverage as the distance between the jets is smaller.
You would really need a much faster flow with 2mm jets to keep up.
The water trickles out of my brush with 2 x 3mm jets at that setting on the controller.
Personally, I would order 4 x 1.4mm jets.
