House and pressure Washing Equipment

There seems to be two areas of thought when it comes to equipment for house washing, First is high pressure is better and we are talking 5000psi and up, The other is less pressure but higher water flow around 3000psi.

As we all know when you lift the pressure you always drop the water flow, you cant have both.. Now one of my competitors likes high pressure and advertises he uses 6000psi and it can cut concrete. Now i don't think that's a smart way to go as damage is always on the mind of the home owner and that's the sole reason the whole soft-wash industry has formed and grown where it is.

Now personally i use pumps that run 3500psi and flow 7 gallons a minute and i find this a great set up for washing house and the chemicals and soaps we use do most of the cleaning and if pressure is needed than 3500psi has always been heaps to get the job done.

Plus with high pressure above 5000psi i don/t know to many hot water systems that can handle that high a pressure so you loss that whole section of the market.

But in saying this a little bit higher pressure could come in hand when your cleaning concrete or stone.

I would like for you guys to comment on what you use and what you find that works.

Thanks
