Scottpat Posted February 29, 2008 Report Share Posted February 29, 2008 I have searched the site over and over and I can't believe that this had not come up. I know that I have seen it discussed but I sure can't locate anything. We all know that it is wrong to connect an A/C condensation line directly to a waste line or DWV. I have searched the IRC and I can not locate the verbiage that states it can not be done. M1411 says the condensation needs to go to an approved place of disposal. Now what is that? Need some help locating this to back up my call on the following photo. I have them on the way the line is connected but not on connecting to the waste line. That 4" line is from a toilet!

Scottpat Posted February 29, 2008 Author Report Share Posted February 29, 2008 Thanks gentlemen! Now my client is fighting with the builder because he builds in a county that does not enforce or inspect to any codes. One of the more memorable quotes from builder; "I do not build homes I build shelters." Class act of a builder! Quote Link to comment Share on other sites More sharing options...

That reminds me of something I used to tell clients buying new homes: "Builders aren't in business to make great homes, they're in it to make great money."

fqp25 Posted February 29, 2008 Report Share Posted February 29, 2008 Bad placement of the clean out - I feel sorry for whoever has to open it up to get whatever obstruction may be sitting in that sanitary tee. Quote Link to comment Share on other sites More sharing options...
Brian G Posted March 1, 2008 Report Share Posted March 1, 2008 This is my favorite answer to that issue. From the 2003 IRC, in Chapter 31, Vents: P3103.3 Use limitations The plumbing vent system shall not be utilized for purposes other than the venting of the plumbing system. How's that for simple and right to the point? ...shall not.... No ambiguity there. Brian G. Not That It Stops Anyone [:-irked] Quote Link to comment Share on other sites More sharing options...
