Review on Lasalle Bristol 74PV240BB Vent Valve by Isaac Logan

I bought this exhaust valve as a direct replacement for the existing exhaust valve on my 2014 Sunseeker 3170. It was the exact same 1-1/2" R&B 2 check valve. It was a problem with my gray tank smell. I removed the old valve and cleaned it, which worked, but decided to replace it. Now a scam, that Picture shows the outlet valve and link pipe I only have one outlet valve I don't need a link pipe but I don't like pictures that don't show exactly what I'm getting If you were to fit a new one firstly the pipe would be missing and for the price it should this don't happen.Hope the seller fix the photo and reply the problem.
