Visually inspect all bonded joints for proper insertion and adhesive cure prior to pressurizing the piping system. A gap between the adhesive bead and the fitting shoulder indicates that the possibility of joint failure exists. Make any necessary repairs before pressurizing the piping sys- tem. See Page 13 for potential causes of joint failure. 2. Check the integrity of the joints by pressurizing the system to 25 psig(0.172 MPa)and holding the pressure for a minimum of one minute,then soap all joints to test for leaks. 3. If there are no leaks,raise the line pressure in the system to a maximum of 50 psig(0.345 MPa). Again hold the pressure for at least one minute,and soap all joints to check for leaks. ■MA4. As serious personal injury or death can result,the X pipe inspector should take precautions for his/her personal safety and protection against flying debris, and also against the whipping action of the pipe, which can result from the sudden release of stored ener- gy. Goggles should be worn to protect against flying debris. 5. Avoid personal contact with the piping system while it is pressurized during testing,except for the actual ■ checking of the joints for leaks. Absolutely no one should be in the trench while the pipe is being ini- tially pressurized for leak testing. Notify all site personnel before beginning the testing procedure. 6. Do not straddle the pipe during testing or while checking the piping system for possible leaks. (1)Do not use these testing procedures and safety precautions for Smith Fibercast secondary containment piping systems. See page 25 of this manual for testing procedures for secondary containment piping systems. RED THREAD IIA Pipe & Fittings 14
