PRESSURE TESTING THE PRIMARY <br />Pressure testing primary pipe involves two procedures: <br />1) Testing each run of pipe individually before installa- <br />tion; follow instructions below. <br />2) Testing primary pipe after entire system is connected; <br />see page 5. <br />Pressure Testing the Coupling <br />A) Apply lubricant (non- <br />D ® granular, clean grease or oil) to <br />inner surface of copper washer <br />(WS1000 for 1-1/2"; WS2500 <br />11a► for 2-1/2") to aid in keeping <br />copper washer aligned and ro- <br />Important. Do not use Iubdeant tating freely until seated. Place <br />containing particulate matter. copper washer on cone seat of <br />test plug. Thread test plug into <br />coupling making sure copper <br />washer is aligned correctly. <br />Tighten plug sufficiently to <br />deform copper washer (mini- <br />mum 60 foot pounds). <br />60 PSI <br />60 PSI <br />B) Pressurize primary pipe to <br />60 psi (or that which is required <br />by local code). Allow pipe to <br />stabilize under pressure ap- <br />proximately 15 minutes. Ex- <br />amine gauge for pressure loss <br />which may indicate leakage in <br />assembly. After completing <br />test, if pressure is lost, remove <br />test plug from female fitting, <br />look for debris or misaligned <br />washer, and repeat sequence. <br />If pressure is lost again, cut off <br />coupling and recouple. <br />After successful completion of pressure test, remove test <br />plug and copper washer. Copper washers can be reused <br />for all pressure tests. <br />A NEW COPPER WASHER MUST BE USED FOR FINAL CONNECTION. <br />When testing primary pipe, trapped air between the lay- <br />ers will escape. This is not a leak. <br />(Pressurizing the pipe to 90 psi at this stage will reduce the <br />time it takes for the trapped air to escape.) <br />• <br />ASSEMBLING THE PIPING COMPONENTS <br />Carefully remove the red plastic caps protecting the threads <br />and beveled sealing surfaces on the brass Elbows, Tees, <br />Y's or Adaptors. Inspect the beveled sealing surfaces for <br />damage and immediately replace the protective caps leav- <br />ing them in place during all further steps, until just prior <br />to the final connection of the primary piping. <br />Step One— Assembling the Tee/Elbow [with impact valve] <br />A) Secure riser pipe (1-1/2" <br />for 1-1/2" primary; 2" for 2-1/ <br />2") in vise and coat threads <br />thoroughly with product com- <br />patible pipe joint compound. <br />Pipe threads must be 1" max.; <br />longer threads may keep pipe <br />from sealing in fitting. <br />B) Thread appropriate tee fit- <br />ting (TE 1500, TE2500, TE2515) <br />or 90° elbow fitting (EL1500, <br />EL2500) onto riser pipe and <br />tighten until seal is obtained. <br />C) On opposing end of riser <br />pipe, coat threads with pipe <br />joint compound. Thread on im- <br />pact valve and tighten until <br />seal is obtained. Make sure <br />impact valve mounting holes <br />are parallel with fitting inlets. <br />Note: Use boss mount impact <br />valves only; U -bolts cannot be <br />used for mounting to TCI dis- <br />penser sumps. <br />D) Assemble mounting bracket <br />onto boss mount impact valve. <br />Do not make final connection to <br />stabilizer bar until all primary <br />piping connections are made. <br />Step Two— Connecting the Primary Pipe <br />A) Screw pulling cone into coupling at one end of primary <br />pipe. Attach static grounding wire (optional), in lazy <br />spiral, to end of pipe to be pushed or pulled through <br />secondary line. <br />Page 4 - Enviroflex Instructions <br />B) Place primary pipe with <br />pulling cone into secondary <br />pipe opening at sump. Push <br />primary pipe through second- <br />ary line. For piping runs with <br />multiple curves or long runs, <br />pulling rope may be desired. <br />is <br />• <br />
