Col...What you have is "good flow"...everyone should have between 50 and 90 PSI mains water pressure.
Everyone gets mixed up between "flow" and "pressure"
Plumbers often turn down the stop **** or gate valve or ballofix fix to stop pipes banging or water splashing over your worktop when the cold water tap is turned on full. This reduces the flow....but not the pressure.
We have great 'pressure" and reasonable "flow" and the Gilmour doesn't come anywhere near this lance.
I'm not saying "Nah Nah...mines is better than yours" I'm only hoping that if someone reads this...has a power washer and has the choice between a Gilmour and a Power Washer foam lance...they think twice before buying a Gilmour.
I also noticed that I use less chemical with the foam lance...but as ever YMMV...
