dancobian,
Sorry for the digression, but I think the one thing that majakdragon and I agree on is that you should check with your local building dept. to see if you're allowed to connect to that clean out. :thumbup:
If you are able to connect there then I envy you.. It's a lot of digging and/or cutting to tie into a waste pipe here in NY.

majakdragon,
You could, but I would just run a pipe from the sink to a grassy area and dump the water there. You are not polluting since the water does not contain fecal matter por other human waste. You may need that cleanout some day.
If you look at the above quote, you said nothing about checking local codes. (You mentioned them after I did.. perhaps I jogged your memory?)
It was also purely your opinion.
You also instructed the OP to violate CA code (and the UPC in general AFAIK).
You also did not address the OPs original concern of whether they could tie into the clean out.

PS - I don't like to turn threads into un-informative arguments that are completely OT. Feel free to rebut, but I've said my piece.
