Every drop of solution the machine puts down goes through a valve or fitting on its way there. That means every problem with coverage, spray pattern, or flow rate ends up being a valve or fitting problem somewhere upstream. Once you know that, diagnosing solution issues gets a lot faster.
This is the genuine Nilfisk Advance OEM COUPLER INLET SS316 70-50MM, part number 4072100144, brand new in the box. Sticking valves and leaky fittings are cheap to fix and easy to overlook. Well worth the check when the machine's underperforming.
