Bigfoot Air Admittance Valve

[Melanie722]

I live full time in my Bigfoot 30MH29G. I purchased my rig for a good price knowing I will have to do some repairs and maintenance which I’m fine with.
I believe my air admittance valve is bad under my kitchen sink. I can see it but it’s way in the corner of my L shaped counter cabinets and completely unreachable. Does anyone know how to access this without having to cut through?

Just curious…What makes you think the valve is bad? I’m truly just curious, because I don’t know how to help you reach it!

Can you post a picture of the underside of the sink cabinet and/or the area where you think the valve is or should be?

There’s an odor coming from the grey water tank. Seems strongest when I open the cabinet under the sink. After doing some research that seems to make the most sense
