Hi, you just answered a question I had about the Model:IRGTL425 coupler and check valve, thanks for your quick response! One additional thing: the coupler is working without it, pouring Guinness fine. Is there a risk of backflow or something? I don't see a difference without the check valve, and I do have a normal regulator on the tank.

You will be losing a lot of Nitro without the check valve so it might be dispensing ok but you will lose Nitro without one in the coupler. Thank you for your question and hope this helped.
