unger n lite brush head ! ! !
My advice....Hose Reel with Wheels and 100 Metres of 8mm Hose.Rectus 21 connectors (Male on pole hose and female on reel hose)22ft pole - Unger N Litre Brush Head - Pencil Jets....maybe think about safety cones, something to hold your pole's in the van, handheld TDS Meter, misc spare's.....I assume that system has a 100 psi pump?
Unger brush was just a joke.
