I have a double sink. Left side has a garbage disposal and the right side
does not. The left side has a trap then drains to the right side which then
has a trap too.
Once in a while when I run the garbage disposal it vibrates and shakes and
some fitting will come loose and water splashes everywhere. I had this
happened twice in the last three months.
So, I think this is because the whole contraption (done by last owner) has
too many fittings. I counted nine.
Is the picture below the way it should be hooked up? I kind of think may be
the trap between the garbage disposal and right drain is not needed. Any
See picture here:
I'm not a plumber but that install looks ok to me. You want the trap on the
for an example).
The fittings don't look excessive to me, but then I"m not a plumber. Mostly
standard plumbing parts -- I was expecting something really cobbled together
from your descripition Just crank the nuts down a bit more with a wrench
(but not so tight as to break something!)
Yep, there should be no trap between the garbage
disposal and the other drain. The disposal
should dump into a single pipe that can slant
slightly down to the main drain. Probably the
former owner just used what he had. But it looks
like the pipe between disposal and the main is
cocked a bit and one end or the other needs to be
adjust up or down to seal well.
The disposal should not vibrate, either you are
(1) grinding stuff that should not be ground, (2)
the disposal is bad, or (3) the unit is not tight
to the sink or the sink isn't tight to the cabinet.
All the non plumbers posting should not post, as they are guessing.
The installation is wrong. The disposal should have an extension
tailpiece on it and the disposal trap should go directly into the
drain. Put a wye at the wall so both traps can connect there. Right
now the disposal goes through two traps.
If you wish, you could use one trap for both. Come out of the disposal
with a twinning kit made for double bowl sinks. Use an ell under the
sink and a flanged tailpiece on the disposal. Then connect at a tee
that drops into a trap.
My first suggestion would work best though.

No, the gd trap is not useful.
If I were you (and about two years ago I was. My trap fell apart because
the plumber who installed it was an idiot; much like yours) I would pull the
whole mess out and replace it without the trap. You can probably reuse a
few of the components; but that stuff is so cheap it is not worth having
ground up refuse all over because you wanted to save $3.
