Hi Folks ,
I'm planning a rough in for new kitchen and am currently working on drain layout. The new sink is on an exterior wall that WAS 2x4 studs I furred this out using 2x 6's purely in order to keep the pipes from interfering with cabinets etc. I plan to stub the 2" drain 14" up from slab to allow for disposal etc. In the photo the sink drain on the right is dropping 1/2' per foot ,the run to the nearest drain (lav) is 5 feet and that point there is a 2' vent up through the roof.
1st Question is can I wait this long (5 feet) and drain into this and use this existing vent or should I install a vent where I have my red vertical arrow and hook them up in attic?
I'm also putting a new sink in the lav along that stud wall on the left of photo so my
2nd Question Can I drain this into the same lav drain as above and use that same vent, distance from sink to lav 4 1/2 feet.
3rd If I can drain both into this lav drain at that point am I correct in saying the fitting is called a Double combo Y -1/8?
Thanks
