KEW pressure washer question - Contractor Talk - Professional Construction and Remodeling Forum

I have a old (1985) Kew "hobby" pressure washer that works great for what I do. I had to replace the hose unit complete. The problem is that the new hose will not fit onto the pump. I think it might be a metric thread.Can I purchase an adaptor to make the new hose fit.

I have the same unit and need to know how you regulate the pressure on it?

Not sure what you mean regulate the pressure: the tip on mine turns to make the pattern change.

Ok I have been able to attach the new hose and wand to the machine. The new hose is 25 feet 5/16 the old hose is 25 feet 1/4 inch. With the new hose the machine will bulid pressure but pulsates all time ,back to the old hose all is good ,whats up with that.

Lot of difference in the diameter of the hoses in terms of volume. I may be wrong, but I think I have seen Teetor post something on this. Seems like it goes something like a quarter increase in pipe equals more than a quarter increase in volume of liquid being delivered through the hose or pipe, so I guess the pump/engine has to work harder.

I bet someone in the plumbing section could answer this.
