Let’s get right to it with some steam-trap advice.
If the F&T trap is the same size as the pipe, it’s the wrong size. I was checking the size of trap that was at the bottom of a 6-in. main that went up 35 stories in a building. The proper size for that trap would have been 1 1/4 in. Of course, the trap that was in place was much larger and that’s the reason why it had failed. An oversized F&T trap barely opens to dump the little bit of condensate it has to handle. The trap’s pin rides too closely to the trap’s seat and that leads to metal erosion of both the pin and the seat as the condensate screams by the barely open exit hole. I asked the engineer why the trap was so large. He said that 1 1/4 in. would have looked stupid. Really.
