Hi everybody, I've just purchased an 18 inch Whirlaway on castors (pressure washer 3000 psi, 4 gpm) and had a couple of questions I hoped someone could answer. 1. What height should the nozzles be above the surface of the ground? I had to adjust the castors to level it up and was wanting to know what the standard height should be. 2. How can you tell what degree nozzles you have installed in your surface cleaner and what is the best angle to use, or is it just trial and error? 3. Most of my work will be mainly cleaning concrete pavers which should handle 3000 psi but I am assuming I will be asked to clean a range of different surfaces, so what is the best pressure to clean: - Concrete (new) - Concrete (older and showing aggregate) - Concrete (sealed with a wet look sealer - would you treat this the same way as you would wash a house?) - Asphalt Thanks in advance, Brett

Hi everybody, First thing - what a great website! The amount of info and knowledgeable people on here is amazing. I have just purchased my first decent pressure washer, 3000 psi at 4.5 gallons per minute (cold water) and an 18 inch whirlaway on castors. I lay pavers for a living and thought I would expand my business by offering a cleaning service. For practise, I cleaned my own pavers at home. The whirlaway was pretty sensational but since my paving is surrounded by gardens with bark and pebble mulch, I couldn't clean right up to edge with the whirlaway and was left with a 2 inch strip around the outside perimeter. So I thought I would clean the rest with my wand, which cleaned the paving but unfortunately also ended up blasting all the dirt and mulch all over the house much to the annoyance of my wife. The question I have is, what's the best way to clean the edges around garden beds without blasting dirt or mulch all over the clients house? Thanks, Brett

Hi guys, Thank you all for the great advice. As someone just starting out in pressure washing I really appreciate you all sharing your tips of the trade. Cheers, Brett

Thanks for the replies. Brilliant. It's funny when you think about it - working from the outside makes perfect sense yet here I was trying to design some sort of special shield to attach to my wand! LOL One other quick question if you don't mind, how do you guys get on when rinsing off a job and there is nowhere to rinse to? In other words, the water is puddling and there is no appropriate place for the dirty water to run to. Thanks again, Brett
