Dear Sir or Madam:
I wish to request an Alternate Materials and Methods of Construction Equivalency as listed in 301.2
of the Uniform Plumbing Code for an installation of an Air Admittance Valve for an Island Sink
installation.
The Permit # is 2008-0326, and is the residence of Larry Beard. This project is a remodel of an
existing structure, and addition to the same structure. The addition is a slab on grade construction,
added to a standard Rambler style of house with an existing crawl space. There is no second, or
additional: story to the existing structure_ The Architect has called for and specified the installation of
an Island Sink, with a base cabinet of 24 inches in width, and cabinets attached directly to the side
.and to the .back of the sink base cabinet. There is no 2x4 stab wall in which to install a Foot
Vent(section'909.0 of the UPC), and not enough room to install said Foot Vent within the sink base
cabinet without extending into the cabinets next to the sink base.
The:installation of the Air Admittance Valve would be installed as follows.
2" ABS Vertical rise out of the concrete within the sink cabinet.
2" ABS Wye with Cleanout Adapter and Plug for clean out application.
Short 2" ABS riser with a 2"x11/2xl 112 ABS Sanitary Tee for Trap Arm connection.
1/12" ABS riser with Female Adapter to connect Air Admittance Valve
Thank you for your consideration in this matter.
CEO, Simple Solutions Inc.
