Question : I have a lateral drain pipe coming from the kitchen sink upstairs. I need to get more pitch for this drain pipe.I cant because I have a shut off valve for an outdoor hose spigot in the way !
Any suggestions would be appreciated ? I have pictures.

Thank you.

If that was mine to do, I would cut the overhead horizontal pipe, disassemble the valve and try to unsweat it from the lower pipe stub. I would install a coupling on top of the stub, run up and over the drain and install a new ball vale on the overhead horizontal run.

perfect

Okay. I temporarily remove the horizontal drain so I can work. I install a coupling. The piping goes in the same direction vertical against the wall behind the drain pipe that will later be reinstalled ? Then I install a ball valve downstream ?

the normal water flow is from the horizontal run INTO the hose cock

the valve is there for 'frost proofing' during freezing weather (close inside valve permitting the OPEN hose cock to drain and empty)

therefor you are relocating the valve UPstream to the horizontal to provide clearance for the drain pipe

Relocating the shutoff as described is your best option. Plan B would be to use a pair of 45's on the drain pipe to bump it out from the wall and allow it to run in front of the shutoff.

I am really thankful for all of everyone's help.
