Cheers Jeff..that is exactly what i was after.
The pressure washer from northern tools is not adjustable pressure so is this a problem if you use the low pressure nozzle.....
Also on domestics will you get water ingress under the soffits/fascias ?
Sorry for all the questions....
No it doesn't have adjustable pressure but watch the video and I tell and show you to stand back to reduce the pressure.
The black one is useless for any thing apart from applying your detergent, once you applied your detergent use the white Jet for normal cleaning and the yellow one for heavy duty cleaning but be very careful with the yellow one it can strip off paint.
This is a question asked by all newcomers to the lance regarding water ingress into the roof space but I'll be very honest, I have never had that problem or at least never any complaints and I also do my own and checked the roof space after and its always was bone dry, Don't direct the jet into the vents but if you have to then stand underneath because the soffit overhangs a house and any water sprayed into the soffit will not go into the roof space but Just like any Job be aware of your work procedure and you'll be fine.
Take care with the round disk type vents because if your not careful you can dislodge them and you have the fun of putting them back in, if it ever does happen then a small piece of a used bar of soap stuck to the back of your brush, stick the vent onto the soap and stick the vent back into the hole but its best to avoid blowing them out in the first place.
