Greetings!
I have just completed the reinstallation of a garbage disposal into a new stainless sink in our kitchen, and while the install appears to have been successful, I am concerned about one thing.
The previous sink into which this disposal was installed was essentially flat on the bottom, and the disposal mounting flange connected flush against it. The new sink however, has very slight angles toward the drain, and thus is not similarly flat on the bottom. As a result, the flange does not (and cannot) be secured flat against the bottom of the sink . When I attempted to use the disposal wrench to lock the the appliance into the ring, the entire assembly including the flange started to rotate, implying the flange wasn't tight enough - but I was afraid I'd already tightened the screws as much or more than was possible without risking damage to either the flange or the sink! Arrggh!!! I finished the rest of the connection/installation, and it isn't leaking...but....it obviously isn't as secure as it should be!!
So, now...my concern is that when I start using the disposal, the torque of the motor will eventually cause that disposal to try and rotate in place slightly, possibly loosening the plumber's putty used to seal the top mounting flange to the sink and creating a leak. I was concerned about trying to tighten the screws on the bottom of the flange excessively and risk damaging/bending the sink itself or squeezing out too much of the putty on the top of the flange and inducing a leak.
Are there some special considerations regarding using these standardized ring-lock flanges on stainless sinks that I'm overlooking or otherwise unaware of? Right now, the disposal is in place and working, but I'm not entirely confident it is as secure as it should be. Thought I might solicit opinions from the good folks here about what, if anything, I should try next - including just leaving it alone and seeing what happens as we start to use it.
Thanks again.
