The drain spud continues to break. A.K.A.(#811501 Nozzle Screw). It is an old box. Seasonal ice cream shop. The drain heater is working. The drain is clear. I tried to protect it with a guard. Not having problems with any other T49 boxes. Is this abuse or am I missing something?
What condition is the drain pan metal in? Drain pan heater? In other words, not being able to see it, Is it icing and the freezing process forcing it out or cracking it. Or is the fitting pulling out of the tapered area becuase the metal isn’t there fully to seat it.
