only by:
All gas pipings and fittings shall be sound
and free from sand holes. No gas fitter's wax cement shall be used.
All gas pipes shall be carefully hooked or strapped
so that the fittings are not strained by weight.
Gas fittings shall be used in making turns.
Leaking fittings and pipes shall be removed.
Only long screws or right and left couplings
may be used in concealed piping.
Pipes shall be so run that there shall be no
"trappings." All pipes shall be run so that they grade back to the
risers and thence to the meters.
The Plumbing Inspector shall examine all gas
piping after it has been completed but before it has been closed in.
A pressure test of five pounds per square inch, "10 inches of mercury
column," shall be applied. After the work passes such test and complies
with standard good practice, a certificate of approval shall issue
upon request. For each inspection of gas piping and fixture installation,
a fee of $2 shall be paid.
