I have something strange going on with my disposal. When I pour a
bucket full of water or even when I'm simply trying to drain the sink,
the drainage is very slow (without the garbage disposal running). If
I stick a fork or something into the drain and hold back the flaps of
the splash guard the is a big rush of bubbles. After 2 or 3 seconds
of bubbles, they stop and the sink drains fine. Therefore, there is
some sort of air lock happening.
If I turn on the gd before the water drains I get a huge splash of
water out of my 2nd sink.
My setup is 2 sinks and I've connected the dishwasher to the port on
the disposal. The disposal is a Kindred:
