In my basement furnace room I have a 2" black ABS vent that T's off into 2
pipes going down into the slab. Kinda looks like an 'h' where the horizontal
jog is about 5' above the slab.
What is the purpose of this double pipe into one? I have seen this is other
homes also.
I put a freezer in there and now have trouble getting to the water softener
back behind the furnace. I assume I can't just cut off and cap one of the
pipes but I could reconfigure the pipe so that I can step over it by putting
in a couple of 45's or three 90's and jog over and up. Is there a problem
with reconfiguring the vent pipes?
Thanks
Kevin
