I need to move the drain location under our kitchen sink slightly and
I would like to do it on paper before I start cutting and hacking.
Does anyone know where one can download dimensional drawings for PVC
fittings -- specifically the 1-1/2" sch 40 fittings?
It all started when I remodeled the kitchen. I had to move the sink
base over 3". I knew where the drain exited the wall relative to the
original sink drains so I moved it over the 3" plus an amount to get
it exactly centered between the sinks. So far so good.
Then I wanted to get a true wye so everything would be symmetrical and
orderly. I couldn't find a 2x1-1/2x1-1/2 true wye anywhere and I
couldn't do it with reducing fittings because of the add'l length.
That's when my plan went off the rails. At that point I settled for a
regular reducing wye. That put the straight portion just a little too
far from the one drain to allow the P-Trap radius to span the
For the time being I have one of those adjustable down tubes, the ones
that look like a flexible drinking straw, and that just bugs the hell
out of me knowing I had screwed up in my planning.
I plan on using two 22-1/2 deg. street elbows to offset the straight
end of the wye. I know how much the drain needs to move to be close
enough to the down tube and I know how much space I have perpendicular
to the wall and that I why I need the dimensions.
Life may have been easier if I wasn't so anal.
I dry fit to get an idea and then assemble from one end. As I add
pieces I recheck because pvc goes together a little more when there is
glue on it. Make the cuts on the straight parts only after you have
assembled up to there.
Instead of a "Y" use a "T" at the wall with pipe stubs either side of
the "T". Ideally a plan view would show the "T" behind the two sink
drains as close to the wall as practical. This is so the traps can be
mostly perpendicular to the wall and allow putting a waste basket under
the sink where as traps running parallel to the wall will use up most of
the space under the sink. Make up height with *pairs* of "90 EL"'s and
vertical stubs as needed.
Basically you want things as close to the underside of the sink and as
close to the wall as practical for storage. A "WYE" sounds like a short
cut but really just introduces problems. You may need more fittings but
the fit will be much easier and yield more storage space.
Buy a length of pipe to custom cut the stubs as its unlikely, unless you
have done this many times in the past, that the first fit will be 'spot on'.
