I have a 4 gpm belt driven cold water pressure washer. I am setting up my trailer now with a 125 gallon buffer tank.
I plan on upgrading my pump to a 8 gpm pump in the future so I’d like to not also have to upgrade my supply line.
I am thinking about a 3/4" interior diameter poly breaded hose.
What size hose would everyone recommend I use from the buffer tank to the pressure washer?
If 3/4" interior diameter hose is fine now but not for a 8 gpm, then maybe I could run dual 3/4" supply lines?
Thanks for your help!
