This is an alternative to the project plan that I referred to in my recent post about testing back to the gas meter.
I need to add a branch line to a new gas cooktop. My initial plan was to cut into a 1" pipe near the start of the current gas distribution system, and create a new 1" branch feeding the new cooktop, as well as allow for future expansion to a fireplace and possibly a Weber grill.
This plan would require either the inclusion of a union as part of the mid-run cut, or if that would not be allowable because of possible closing of the wall (not currently planned), then use of a left-right coupling.
An alternative would be to branch off of an existing tee which is about 5 feet downstream on the current 1" pipe. It has a 3/4" branch which currently is only feeding a dryer through a 1/2" reduction.
The dryer is going to get moved as a result of the next remodel project, so this branch could be configured to feed both the cooktop and dryer, provided of course, if the capacity math allows.
My question is:
Since this branch point is about 3 feet higher than the floor where the cooktop resides, it would require branching out horizontally about 7-8 feet, then down about 4 feet, then horizontal under the floor for about 12 feet, then up to the cooktop.
As the branch point is already 7 feet above the entry point, the resulting pipe path is up and down, and back up again.
Is that something that is not allowed, or just bad practice, or not a problem?
It is a split-level house, so the pipe comes through the outside wall a foot or so above the floor, up to the ceiling, then over to the wall of the adjacent split floors, down 4 feet to the ceiling of the adjacent basement, across its ceiling, and then up through the kitchen floor.
