Dry return pitch

I see in some other posts that the dry return should be pitched 1/4" per foot down.

Does this look adequate?

    um... just barely. With that shallow a pitch though, you need to be very very careful to be sure that it really is maintained everywhere. Minimum 4 foot level; better a laser or string line end to end. Also it will be best if the only system venting is at the low end, hopefully at the boiler.
