Let me see, I have bought quite a few parts from Paul and Bill at The Powerwashstore. Two hot water machines. If you haven't tried his Water Dragon Hot water machines, you ain't lived. Narrow profile, tanks come in the size you want, and they are very easily serviceable. Awesome machines, for a fair price. I also have a surface cleaner I got from them, although if I remember I bought two other surface cleaners earlier in the year, and all of my spare parts, nozzles, unloaders, etc. When you pretend to have 24 rigs on the road, it takes some stuff to keep them going and a distributor you can rely on.
