Re: Question for plumbers said by towerdave:The reason given to me by the plumbing inspector was that the disposals were wearing out early due to the water (and maybe what's in it?) coming from the dishwasher. Which doesn't really make sense to me, but I'm not a plumber.
Yes, because hot water with detergent is pretty caustic to stainless steel and plastic, which was what almost all the disposals were made of last time I looked at them. I can maybe see that it keeps the grinder wet so it might corrode, but I run my sink faucet far more then my dishwasher so I don't think that could even be it. |

I'm not a chemist either, but I can see that, and he may have even mentioned the detergents.
Either way, it's code in IL.  And I'm glad he mentioned it to me when he did, because we had a new disposal and hadn't punched out the knockout yet.
Before we re-did the kitchen the DW was draining into the disposal, but that wasn't an inspected installation.

And because it didn't cause me any headache, I was happy to comply.
