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 52).
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 53, for propane/LP or Figure 54, for
natural gas). Apply noncorrosive leak detec-
tion uid to all joints. Bubbles forming show
a leak. Correct all leaks at once.
