Anyone who is serious about pressure washing will know this is a serious piece of equipment
You said it so if people are serious then they want to know exactly what they're getting.
Would have offered a refund if a buyer later found out it doesn't do the 21 LPM you claimed?
It sounds petty but it could have led to them spending more money on the right turbo nozzle etc
Good luck getting what you want for it, my intention wasn't to jeopardise the sale.
