View Full Version : Old Alternative Methods Caveat - Old Plumbing Code (Custom Showers)
05-06-2011, 08:56 AM
I'm on the hunt for some more information on what the "Old alternative methods caveat" which I'm told is written into some local code books way back when and is still included in local code today. With this code it seems possible to build your own drain and get approval to do so. Or so I'm told.
Do we have any Bathroom Contractors, Tile Setters or Plumbers who have any information on this "Old Time Plumbing Code". This advice is online and I fear someone will try and go this route only to find out at the end of the job it all needs to be ripped up.
Thanks for any help. When and if I get any information I'll post it back here for reference.

What do you mean by "build your own drain".....are you talking the yard septic, the house dwv, or something local to the shower?
"alternative methods caveat" would mean "beware" of them, or more precisely, beware of probems they could cause.

I read online that another tile setter builds his own "Code Approved" linear drain and uses this "Old Alternative Methods Caveat" as a means of getting it accepted. I have a strong feeling that this is a lot of "Hot Air" but if true would open the doors for some "Tweaking" and "Creative Manipulations" of my existing linear drains.
Is there such a thing as an "Old Alternative Methods Caveat"?

"R104.11 Alternative materials, design and methods of construction and equipment. The provisions of this code are not intended to prevent the installation of any material or to prohibit any design or method of construction not specifically prescribed by this code, provided that any such alternative has been approved. An alternative material, design or method of construction shall be approved where the building official finds that the proposed design is satisfactory and complies with the intent of the provisions of this code, and that the material, method or work offered is, for the purpose intended, at least the equivalent of that prescribed in this code. Compliance with the specific performance-based provisions of the International Codes in lieu of specific requirements of this code shall also be permitted as an alternate. "
This is the suggest code from the 2009 ICC Code Book.
In many cities Plumbing inspectors will not approve a Kerdi Drain - I can't imagine that you can pull out one section at the back of the code book and say "Look here I can make my own because you can't prevent me from using my own stainless steel".
I'll search for a similar clauses in our Canadian Code Books. Last time I checked we where still using the 2010 Plumbing Codes of Canada and our Provincial Code Books come inspection time.

I take that wording to allow wiggle room for ENGINEERED design solutions using materials not specifically listed by the AHJ. Around here, materials and fittings are listed and approved by IAMPO. In general, the AHJ takes that a final OK. I don't think John Q Schmuck Buttcrack can slap something together and convince anyone it is OK. They are going to want a signature on a plan, and the signature better say PE behind it.
