1 PLUMING SYSTEMS ND REFERENE GUIDE Uponor quapex with PEX-a Pipe Support ommercial Plumbing Engineer Quick-reference Guide This quick reference guide is designed for architects, building officials, engineers and mechanical contractors interested in Uponor ommercial Plumbing Systems. It describes general installation recommendations that use Uponor quapex crosslinked polyethylene (PEX-a) pipe and ProPEX fitting products. Uponor is not liable for installation practices that deviate from this guide or are not acceptable practices within the mechanical trades, codes or standards of practice. lways refer to local codes for additional requirements. For further assistance, refer to the Uponor Plumbing Design ssistance Manual (PDM) or contact Uponor Technical Services at or Uponor quapex (PEX-a) Pipe The ore of Uponor Plumbing Systems Hydrostatic Temperature and Pressure Ratings Uponor maintains standard-grade ratings for Uponor quapex pipe as tested in accordance with PPI TR-. Uponor PEX products have the following temperature and pressure ratings: 00 F (9 ) at 80 psi (55 kpa) 80 F (8 ) at 00 psi (689 kpa) 7.4 F ( ) at 60 psi (,0 kpa) Excessive Short-term Temperature - Pressure apacity: 0 F (99 ) at 50 psi (,04 kpa) tested up to 70 hrs (STM F876) and 48 hr (S 7.5) In accordance with Section 6.6 of STM F876, the minimum hydrostatic burst pressure for " pipe is 480 psi (,09 kpa) at 7.4 F ( ). For 4" pipe and larger, the minimum burst pressure is 475 psi (,75 kpa) at 7.4 F ( ). Uponor s NSF-approved quality lab performs daily burst pressure testing on all pipe sizes above and beyond the STM F876 standard. ll samples are tested at 7.4 F ( ) and burst at an elevated pressure of 800 psi (+/- 0 psi) nearly twice the pressure requirement of STM F876.

4 Suspended Piping For suspended runs of piping, Uponor quapex can be supported by the same conventional means as metallic pipe using copper tube size (TS) pipe hangers or supports. Uponor recommends using hangers and supports designed for use with plastic pipe. Use PEX-a pipe support channel that continuously supports the pipe to achieve the same support spacing as copper pipe. Per NP Table..4.5., the maximum horizontal support spacing for PEX is " (0.8m). If running pipe in a horizontal assembly requiring fire-resistant construction, pipe must be continuously supported or support spacing must not exceed 6" (0.4m) for " and smaller PEX and 4" (0.6m) for 4" and larger runs of PEX. Use of support channel or PEX-a pipe support in conjunction with TS hangers is an alternative to the " (0.8m) on-center support spacing requirements. Support channels allow for greater spacing between hangers; 5' to 8' (.5m to.4m) on-center spacing is achievable if the support channel is installed per the manufacturer s instructions. For more information regarding support solutions, contact Uponor Technical Services at or [email protected]. 8' (.4m) On-enter Suspended levis Support Strapping (optional) U-shapped support channel [available in 9' (.74m) lengths] 8' (.4m) On-enter Trapeze Support Strapping (optional) " (0.8m) On-enter Trapeze Support Steel joist eam clamp Threaded rod (size per load requirements) Standard TS U-shaped clevis hanger spaced at max. 8' (.4m) o.c.

5 Risers Risers typically feature Uponor quapex pipe in sizes from " to " with TS riser clamps at the base of each floor. The installation should also include a riser clamp at the top of every-other story to limit the expansion and contraction of the pipe to less than 5' (7.6m). This translates to an expansion of about " in 5' (7.6m) at a 60 F (4 ) Delta T [installed at 60 F (4 ) with an operating temperature of 0 F (48.9 )]. Detailed Riser Installation Uponor quapex pipe risers ppropriate firestop material (must be Uponor quapex compatible) In this application, the piping will snake slightly in areas where it is not constrained. Use discarded framing as a backer plate for the mid-story guide. Ensure the guide is metal with no sharp edges or fire-rated for risers in walls requiring fire-resistant construction. Through Penetrant Firestop The following firestop manufacturers offer PEX solutions as tested in accordance with N/UL S5. M TM Hilti HoldRite HydroFlame TM Metacaulk Nuo Passive Fire Protection Partners ProSet Systems Tremco See firestop manufacturer s website for selection of appropriate fire assembly and product. Plenum Rated Up to " piping in return-air plenums have no spacing limitations if covered with " fire-rated fiberglass insulation. Uninsulated 4" to " pipe in a return-air plenum must be separated by 8" (0.46m). Listing for " pipe does not specify restrictions on spacing requirements. Pipe larger than " may not be installed without " minimum fire-rated insulation. Exposed EP fittings are approved. Pipe in hallway drop-ceiling applications requires special attention due to variances and interpretations of anada building codes. lways check with local code officials before installing Uponor quapex in hallway drop ceilings. National uilding ode (N) Requirements for Plenums Materials exposed in plenums shall have a flame spread (FS) of 5 or less and a smoke developed (SD) of 50 or less when tested in accordance with N/UL S0..

6 ommercial Flush ank Section Detail Wall ssembly Uponor quapex pipe header (size varies) Support Uponor quapex pipe supply (size varies) Surge Pressure and Sound Intensity The main sources of sound in a water piping system are cavitation, surface roughness and water hammer caused by surge pressure. avitation is generally a design issue, so the question is which material will absorb more of the sound if it occurs? Typical polymers will absorb sound in the range of 0 d/cm, whereas metals are on the order of d/cm. For a given change in velocity, the intensity of sound from a copper pipe will be at least 8 times higher than that of PEX-a pipe and peak pressures caused by a quick-acting valve could be reduced by 8-40% by utilizing PEX-a in lieu of copper pipe.

Uponor EP and LF fittings are rated for direct burial in soil per NSF 4. Service Fitting Solution Providers Y McDonald ambridge rass Ford Pack Mueller 0 Philmac PolyGrip Fluorescent Lighting UV and Heat Exposure s a safety precaution against Ultraviolet (UV) exposure from fluorescent lighting, Uponor recommends that all PEX-a pipe be protected from UV by sleeving the pipe with a black material such as closed-cell pipe insulation or HDPE poly sheathing. Protection is recommended when pipe is directly exposed and within 6' (.8m) of the fluorescent light source. In such case, pipe should be protected 8" (0.46m) beyond direct exposure on each side of the fluorescent light source. Furthermore, Uponor requires that all PEX-a pipe be protected from excessive heat by insulating the pipe with closed-cell, fiberglass or other suitable pipe insulation. Insulation is required when pipe is within 6" (0.5m) of the fluorescent light source. In such case, pipe shall be protected 8" (0.46m) beyond each side of the fluorescent light source and maintain a minimum clearance of " (5.4mm). 6

7 " Uponor quapex Expansion Loop Expansion and ontraction ecause PEX pipe expands at a rate of." per 00' per 0 F (7.94mm per 0.48m per 5.56 ) temperature rise, an expansion joint, offset or change in direction is necessary to accommodate the expansion and contraction of the pipe. ompensation for expansion is typically needed every 65' for domestic hot water and every 50' for domestic cold water in a commercial domestic water plumbing system. Uponor offers a preformed " Uponor quapex Expansion Loop (F85000) to make expansion joint installations more efficient.

Therefore, PEX-a pipe does not sweat like copper does. The thicker walls of PEX-a pipe act as an insulator (approx. R-0.9) whereas the heat transfer from copper is much greater than with PEX-a. Uponor recommends insulating all PEX-a domestic hot-water supply and return lines to conserve energy and insulating PEX-a domestic cold-water supply lines when installed in an unconditioned space or poorly ventilated areas with excessive moisture content.
