Equalizer/Hartford Loop Size vs Wet Return Size

krisnet55krisnet55 Posts: 13Member
Im a bit confused here on sizing of the equalizer/hartford loop.
My boiler manual calls for an equalizer/hartford loop size of 1 1/2 inch. However my return line is 1 1/4.
I planning on doing the equalizer in 2' and not sure if:
A: Do the hartford loop in 1 1/4 and then connect it to the return line
or
B: Do the hartford loop in 1 1/2 and then at the lower 90 put a reducing elbow to 1 1/4 to then connect at the wet return

    It's not that critical.
    I would do an 1 1/2" equalizer with your tee to the Hartford loop & return could be a 1 1/2 x 1 1/2 x 1 1/4 tee. That is minimum and will work without any issue at all. If you want to upsize anything that's fine. Will not make any difference whatsoever

    Correct @krisnet55, those arrows are never actually pointing to the Hartford loop connection, but rather the equalizer as it connects back to the boiler.
