Not your standard plumbing question: pipework to plumb in pressure washer?

[crappy]

Ah. My intention is to have it permanently plumbed and connected to power but not powered. I don't mind opening a ball valve and hitting the on switch.

What I don't want is to faff with the extention cord, faff with (frozen?) hose or outside tap.

My plan is to mount it in the garage, drill a hole through the wall and mount a female connector (m22) so when I need to wash the bikes, I just plug the lance and pipe, into the wall, hit the power button and ball valve in the garage and wash the bikes.

Storage means either leaving the lance outside neatly coiled in summer or inside the garage in winter.

I kind of presumed that was the case but I believe there was a little ambiguity over what the actual intention was.

Surely just the existing hose needs poking through the wall with the machine kept inside, you can get external switches for power and water supply. I always "run my hose dry" before switching off to prevent freezing.
