Grey and Black water flush valve

I am having issues with getting water to either the grey or black tanks to flush during clean out. Was thinking both sprayers inside the tanks were blocked,but, after taking the supply line off the black tank, no water came out when switching the valve from grey to black tank.
Looking at the Alpine Coach schematics I'm wondering if the two way valve is defective. Has anyone had this problem before and if so where do I find a replacement ?

Thank you in advance for any advice.

Hmm, does Alpine have an online parts catalog like winnebago? if you take out the part it may have a serial # or some NSN (national stock #) that you can do a google search on. Maybe it's just a generic valve you can even find at Home depot or on line.
For Example I have a numbers matress, and it took a dump on me. so I took the inflator machine out looked at the air valve and googled the part on line. Found the part for $4.98 and bought a hose (tubing) at home depot, and it was an easy fix.
I'm just brainstorming with you. Anyway...good luck.

I'd share but then I would be wondering around asking "Do you know me?"
