Squirtgun,
That is a K-7 unloader with mounting block,
the KZ-1 unloader is optional. The black object is a
pulsation dampener.
I have the same skid, and it's a tank. It runs and runs. The mounting block is especially nice since K-7's seem to fail more often than pressure unloaders. Replacement time is reduced because everything is in the open, easy to get at, just plain better.
I bought this unit for hot water purposes only. I don't run it without the burner on. Mostly used for commercial work.
I have several cold water portables that do everything I expect cold water to do....decks, fences, house washing, etc. Basically used for residential work.
The 13hp Honda with General would be a great starter machine. My first machine was a direct drive, because I had to stretch every dollar I had.
After you see how things work out, you'll eventually want to upgrade to better equipment.
Mark is the guy to talk to for better equipment.
