All exposed pipes, fittings, valves and joints
shall be carefully examined during the open-trench test. Any cracked
or defective pipes, fittings or valves discovered in consequence of
this pressure test shall be removed and replaced by the developer
with sound material and the test shall be repeated until satisfactory
to the Township Engineer. Should the developer elect to backfill the
entire trench, or any portion thereof, prior to testing, the developer
shall locate and repair any leaks which occur during this test.
(c)
While the test pressure is being maintained,
all exposed pipes, fittings, valves and joints shall be inspected
for leaks. Leakage shall not exceed 10 gallons per day per inch of
