A couple of weeks ago I bought a 1/2" air pump from Lori at Pressure Washer Services along with 200' of 5/8" hose and a reel. We also bought a 9HP, 150psi 30 gallon air compressor that we mounted in the bed of our pickup that we pull our trailer with. We use this setup strictly for soft wash applications. Now we can reach the peaks on a 3 story townhome. We have always had an independent soft wash system run by a Honda motor but we were always having problems with it leaking. Our new pump is completely bleach resistant and we never have to worry about the bleach hurting the pump. It's a great system and has cut out time for doing home or building exteriors dramatically.
