PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
1. Disconnect replace and its individual equip-
ment shutoff valve from gas supply piping
system. Pressures in excess of 1/2 psig (3.5 kPa)
will damage replace gas regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas replace or opening main gas
valve located on or near gas meter for natural
gas replace or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection uid to all
joints. Bubbles forming show a leak. Correct
all leaks at once.
5. Reconnect replace and equipment shutoff
valve to gas supply. Check reconnected ttings
for leaks.
1. Close equipment shutoff valve (see Figure 33).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas replace or opening main gas
valve located on or near gas meter for natural
gas replace or using compressed air.
3. Check all joints from propane/LP supply tank
or gas meter to equipment shutoff valve (see
Figure 34 or Figure 35). Apply noncorrosive
leak detection uid to all joints. Bubbles form-
ing show a leak. Correct all leaks at once.
