Just got this, been working away.
I regularly run long extensions of pressure washer hose. 160 metres last week in Leicester.
I have done this now for several years with no faults on any machines and will be going back to Leicester today to do much of the same.
There is a loss of 23psi per 100 feet of hose, so if you start out on 3000 or 4000psi there is still plenty at the business end!!!!
This is the more expensive way of doing it though, if it is only for the odd job (that you need the extra hoses for)
Any problems you can always ring me, cheers
