Hey Ed, Is Condensate Always Trapped?
In this edition of "Hey Ed", Ed discusses if condensate is always trapped or not.
Hey Ed, with system performance, is condensate always trapped? That is a often discussed and argued topic, and the easiest way for me to answer it is on a coil it’s on the negative side of the fan it is always going to be in your best interest to trap it. When it’s on the positive side of the fan, it being the coil, is it necessary and that’s where a lot of the arguments ensue. There are several code verses that say that the drain line has to be at atmospheric pressure and the only way we can maintain atmospheric pressure is with a trap. So, when somebody says you only half to trap on the negative side, if code compliance he is part of the equation, it’s not a correct answer and that’s the way I see it!
