Dead simple

I keep a whole lot of spares in my shed. We use Cleantech alloy poles, put an alloy adaptor in the top with one or two plastic angle adapters, screw a Vikan on that we've drilled to accept jets, drill through the rubber bottom end cap and the top angle adaptor and feed the pole hose through, fit a "Y" piece and a couple of short lengths of hose to the jets, and hey presto!! 18ft WFP for about £75

All bits available from Cleantech and Gardiners.
