Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Fig- ure 26).

2.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.

3.Check all joints from gas meter to equipment shutoff valve (see Figure 27). Apply a noncorrosive leak detec- tion fluid to gas joints. Bubbles form- ing show a leak.

2.Cap off open end of gas pipe where equipment shutoff valve was connected.

3.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.

4.Check all joints of gas supply piping system. Apply a noncorrosive leak de- tection fluid to gas joints. Bubbles forming show a leak.
