Okay, y'all
, let's go back to Plumbing 101.
1) That's a "kitchen sink", right? (At least it looks like it to me.)
2) That's an "indirect waste" connection using the "kitchen sink" trap, right? (Looks like it to me.)
3) This is what the IRC says about indirect wastes and prohibited connections (what cannot be connected where, or, in the reverse, what can be connected where).
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.)
Okay, now let's go to Plumbing 101, the next semester.
This is an "indirect waste" we are talking about, thus the piping is an "indirect waste pipe". Right?
This is from the IRC.
-
INDIRECT WASTE PIPE. A waste pipe that discharges into the drainage system through an air gap into a trap, fixture or receptor.
"through an air gap"
Now, it seems to me ... and I could be wrong again ... that NONE OF THE ABOVE allows that connection, and, in fact, DISALLOWS that connection.
Convince me otherwise.
