Welcome! Here are some tips for using this forum.
Im working on a Weil Mclain peg 45 replacing a old snowman boiler that had a counter flow system two mains running left and right side of the house and each had a drip . I was hoping that someone could give me a better piping diagram then the manual it didn't seem to show a drop header the way I thought it would be piped. I'm not sure where to pipe the drips for the mains should these dump in to the wet leg after the Hartford loop?
