Don't cut, autopsy not called for - yet!
I recall check valve being under dash just before reservoir, as previously mentioned. Perhaps you are simply looking at inline connector between grey & black hoses. The "other hoses" would be to heater core.
Not sure if manually blowing from dash side of black hose is possible. Yes, check valves can clog (e.g. PCV valve, see also Big Jim's recent windshield washer post), although this one is operating in a pretty clean, air environment.
