Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable item(s) or insert appropriate information.

Remove information and requirements not required in respective project, whether or not brackets are present.

Comments, suggestions and recommended changes for this guide specification are welcome and should be submitted as a Criteria Change Request (CCR) .

PART 1 GENERAL

NOTE: This guide specification covers general purpose type plumbing systems. This specification essentially implements the requirements of the International Plumbing Code (IPC). Equipment supports and connections, for either equipment on the ground or in the building, will conform to these

SECTION 22 00 00 Page 7 requirements.

This section contains tailoring options for PIPING, FIXTURES, WATER HEATERS, PUMPS, PRESSURE PIPING, COMPRESSED AIR SYSTEM, ARMY, AIR FORCE,and NAVY.

NOTE: The following information must be shown on project drawings (Item 6 is tailored for ARMY):

1. Only drawings (not specifications) must indicate capacity, efficiency, dimensions, details, plan view, sections, elevations, and locations of fixtures and equipment; space required to replace strainers, filters, and for maintenance of equipment.

2. Show location of wye strainer on building side of water supply valve in each building; indicate wye strainer blow-off outlet with piping to adjacent exterior wall hydrant. Note: This will clean the strainer each time the wall hydrant is used.

3. Show configuration, slope, and location of each piping system such as: above or below floors, above or below ceilings, above or below roofs, above or below ground.

4. Show location of each sectionalizing valve in each water system. Sectionalizing valves should be ball valves.

5. Show location of each solenoid-operated flush valve and solenoid-operated lavatory faucet on project drawings.

6. Minimize the risk of Legionellosis in building water systems by following guidance in the U.S. Army Corps of Engineers Engineering Manual (EM) 200-1-13 (2016), Minimizing The Risk of Legionellosis Associated with Building Water Systems on Army Installations.

7. For Tri-Service projects, minimize the risk of legionellosis in building water systems by utilizing the guidance in the Association of Water Technologies, (2019) Legionella: A Position Statement and Guidance Document, ASHRAE Guideline 12, ASHRAE Standard 188 and the Cooling Technology Institute GDL 159 and (2008) Legionellosis Guideline: Best Practices for Control of Legionella.
