Well.....there's a ton of threads on here about equipment but before the equipment.......there's the need for knowledge.
AC has several modules you can watch and pick up the basics from and there's also a ton of reading you can do right here on the forums.

The Power Wash Store has a double pump system that's not a bad starter set up but the quick connects they send probably need to be replaced before you even start....none the less it's a start.
