I’m planning our next build and would like to move up from our 4k 4 GPM machine. We probably do 95-99% residential, mostly siding and decks, with some concrete here and there. I was looking into the bigger units, but came across this guy: https://www.3rpressurewashers.com/psi-b-k8025hc.html
8 GPM, 2k PSI and runs off the GX390 for around $2500 shipped. I just wanted to hear if anyone has some thoughts on what I’d be sacrificing to go with a unit like this, as opposed to the larger engines traditionally associated with 8 GPM units. Even though my current unit is 4k PSI, I almost never use it at that pressure. I looked up the pump specs, and ran the calculations online and everything is showing 13 HP is enough to get to those numbers. Any thoughts on whether a larger engine capable of a higher PSI will be better for mostly resi work? Any reason I’ll regret buying this and wish I’d have gone with a bigger setup?
