Interesting theory on brush jets.

I always get Gardiners to fit the larger 3mm jets to my brushes to avoid splash back. Much nicer as I rinse off the glass.

this relates to a post i put up about flow rates and splash back
im starting to think along the lines of a wider jet and less pressure,if possible

A wider jet will give you greater volume of water at a lower pressure. Also allowing you to reduce the strain on the pump and connectors. Some of the techniques used in the states have benefit here.
Typically the US windy has no water management issues as there are using an on demand RO with a external water supply.

Th ability to adjust water volume is very beneficial as it will give additional water for rinsing and still allow water management with a tank based system.
