How the system works

Ive been looking for awhile now but I cant really find anything. Even on YouTube that does a good job.

Can someone explain how the plumbing on power washing set up works? I see threads about set ups all the time, but I dont understand how the plumbing works.

Thanks yall

What do you have? Feeding from garden hose or buffer tank?

I dont have anything just yet. Trying to learn how everything operates first. But I would have a buffer tank most likely.

1 inch line from buffer to a canister filter to the machine. Jump line from unloader to injector to reel.
