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 Z7 24014 NOZZLE PLASTIC CREVICE 38MM, part number Z7 24014, 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.
