Devilbiss 1750PSI @ 2GPM, 5HP B&S, $297 at Home Depot about 5 yrs. ago. Countless uses, by me and quite a few friends.
No problems, until this year. It would not start on the second or third pull like it always used to. It would start when the water supply and the hose were disconnected. So I tore down the pump. When the pump was apart, the lube inside looked like silver paste. I started picking out a few pieces of flat metal, and about 10 or 12 roller bearings. Hmmm- there is another roller bearing intact, so I guess there were two once upon a time./w3tcompact/icons/tongue.gif Looking at the owners manual was no good as there is no parts information. I thought, no problem the DeVilbiss website will have this stuff online. Nope, they have a number to call and to get parts info. I'll let you know how it goes.
One thing I did notice in the Owners Manual, that I did not tell the other operators, was that you should not let the unit run without pulling the trigger for more than 2 minutes. (doh)/w3tcompact/icons/blush.gif The pump will become overheated if there is no water flow. I wonder if some of the more expensive units have the same issue?
