A. General: Install per the Uniform Plumbing Code (UPC). Any UPC installation instructions
located in Appendix "I" ("Installation Standards") for a specific piping material specified in this
section applies to the work of this section.
B. Preparation:
1. Clean off scale and dirt inside and outside before assembly. Cut pipes and tubes square
and ream to remove all burrs.
2. Cut pipe accurately to field measurements so work can be placed without springing or
forcing.

1. Install so piping is free to expand, provide for all expansion with offsets or loops where
necessary. Branch connections shall have three elbow spring pieces to allow for
expansion.
2. All changes in direction shall be made with fittings. All radius; shall be long radius.
3. Arrange piping so as not to interfere with access or removal of other equipment or
devices, block access to doors, windows, manholes or other access openings.
4. Arrange piping to facilitate the removal of tube bundles, coils, etc. Provide unions ahead
of screwed valves, traps or strainers on each side of each piece of equipment and
wherever needed to dismantle piping.
5. All piping shall be properly pitched and graded to drain moisture and/or vent air.
6. Each low point shall have an accessible blind flange or screwed plug or cap.
7. Route pipe to avoid liquid or air pockets throughout the work. Provide at high points of
closed systems, collecting chambers and automatic air vents.
8. Make reductions in pipe size using eccentric reducing fittings installed to provide drainage
and venting.
9. Nipples shall be of the same material as pipe. Close nipples shall not be used.
10. Install pipe in neat and workmanlike manner, in accordance with best trade practice.
Install to conserve headroom and interfere as little as possible with use of space. Run

dimpled depth stops shall be provided. The branch tube shall be notched for proper
penetration into fitting to assure a free flow joint. Extracted joint shall be brazed using a
copper phosphorous classification brazing filler metal. Soldered joints shall not be permitted.

water/chlorine solution containing at least 200 parts per million (200 mg/L) of chlorine and
allowed to stand for 3 -hours.
