Newbie here who built a mini WSM. I ordered a AMNPS and tried using it inside the smoker on top of the terra cotta diffuser but I can't get it to work consistently. The pellets seem to burn up really fast...I guess because it's so close to the heat? Anyway, I want to try something like the mailbox mod and connect the AMNPS to one of the smokey Joe bottom vents. I bought a sink pipe like this: It fits the vent great, but I didn't think about the material until after the fact. I'm pretty sure it's chrome plated but have no idea if it's steel or some other metal underneath. Question is, would there be any health risk using this to bring smoke from the AMNPS to the smoker? The pipe would be nesting in/touching the metal of the mini WSM close to the charcoal gate but would not come in contact with the charcoal. Would there be enough heat to cause poison fumes from the chrome plating? I appreciate your help.
