§ 16.12.350. Testing—Procedure for water test.

A.

The water test shall be applied to the drainage system in its entirety or in sections. If the test is applied to the entire system, all openings in the piping shall be tightly closed, except the highest opening and the system filled with water to the point of overflow. If the system is tested in sections, each opening shall be tightly plugged, except the highest openings in the section under test, and each section shall be filled with water. No section shall be tested with less than a ten-foot head of water.

B.

In testing successive sections, the upper ten feet of the next preceding section shall be tested so that no joint or pipe in the system (except the uppermost ten feet of the system) shall have been subjected to a test of less than a ten foot head of water.

C.

The water shall be kept in the system or that portion of the system under test for fifteen minutes prior to inspection.

D.

For successful passage of this test, the system shall be tight at all joints.
