Thats what I'm looking for Clinton, had it on my old lower pressure ninja, only the float wasn't working too well so didn't shut off when full like it should have so you had keep an eye on it and manually turn off. Hose onto tap running to machine that had a screw on tap adapter connected to the float inside. Remember it roughly just can't remember how it all set up.
Got a smaller van so haven't really got the room for a water tank.
Can cope with the emptying Rob, got 2 large (plasterers style) buckets I use. Just the filling, most houses around here seem to have low water pressure as well which means filling each bucket can be minutes.
