I just installed a new garbage disposal and thought I did a pretty good job
considering I had put one in before (not on this sink). Well, I have a
leak, but it only seems to leak when I fill the sink up some and let the
water out, if it is just running through it doesn't seem to leak or if it
does it is only a tiny leak. Any suggestions? I'm thinking I didn't get
all 3 sides of the quick connect thing or whatever you call it for the
disposal connected well, but I can't tell. Any thoughts?
Spread some news paper under the pipes; replicate the leaks and then
check the paper for wet spots. This will help narrow the leak. It
works great for a slow leak.
Check pipe connections for binding. Maybe something is cross threaded.
It Doesn't leak while the sink is filled and the stopper is in? Then you
are probably correct, if the leak is coming from around that area of the
unit. If it does leak when the sink is filled and the stopper is in, I
think that would mean it is in the seam between the sink and the drain
assembly since the 'quick connect thing' would be below that point. As
others have suggested - get under there and be sure it isn't in the drain
pipes past the unit itself. Those would leak more as the amount of water was
increased. Just running the faucet and letting it flow down the drain isn't
putting as much water down as the sudden rush of an emptying sink.
