Can anyone help me please, im pretty novice at pressure washing but get quite a few jobs, i have a petrol 13hp pressure washer, 3500 - 4500psi i think and off top of my head cant remember gpm it gives but can get that tomorrow, 3.5gpm rings a bell.
I did a big pressure washing job today and think its time to invest in a FSC, how do i go about getting one, i know this might sound dumb but are they all the same? Do couplings vary much?
Sorry for being a massive dumbo lol.
