Phillip,
First, thank you for finding and posting the link.
You agreed to disagree, I still state you are wrong.
The difference is that the code *DOES NOT ALLOW THAT CONNECTION* ... period ...
*I* *still* do not understand what you do not understand about "Plumbing fixtures that are
used for domestic or culinary purposes
shall not be used to receive the discharge of indirect waste piping
."
The code does, however, allow two (count them, 1 ... 2) exceptions, and only 2 exception, both of which are stated in the following code sections (which is copied from the previous thread). Those two exceptions are (and these are *THE ONLY* two exceptions): 1) "kitchen sink", 2) "laundry tray". And each has only one allowable connection in their respective exception. You will note that "lavatory" or 'bathroom sink' is not listed in either of those two exceptions.
It is clear, it is concise, and it is VERY SPECIFIC.
From the IRC. (underlining is mine)
- P2706.3 Prohibited waste receptors.
Plumbing fixtures that are used for domestic or culinary purposes shall not be used to receive the discharge of indirect waste piping. (Jerry's note: This is what cannot be connected where, i.e., do not connect an indirect waste to a residential sink or lavatory .... except as noted below.)
- - Exceptions: (Jerry's note: This is what can be connected where.)
- - - 1. A kitchen sink trap is acceptable for use as a receptor for a dishwasher. (Jerry's note: That ain't from no dishwasher, it's from an a/c unit. Thus is does not meet this allowable connection. Thus is meets the "Prohibited" section as to what cannot be connected where, i.e., that is not allowed to be connected to the sink trap.)
- - - 2. A laundry tray is acceptable for use as a receptor for a clothes washing machine. (Jerry's note: While this does not apply here, this deserves to be remembered also. The only thing which is allowed to be drained into the laundry tray (think laundry sink) is the clothes washer.)
I am at a loss to grasp how an intelligent and knowledgeable person cannot grasp such simple, precise, concise, and specific wording. It's not like it says 'maybe' or 'if you want to' or 'or similar sink' in there anywhere.
