No portion of the P-trap or backwash line may be covered until the inspection has been approved. Where a gas piping system is utilized that contains a working pressure greater than 1/2 p.s.i., an air test of at least ten pounds per square inch (10 p.s.i) on a diaphragm gauge that has a set hand and has a maximum range of twenty (20) p.s.i. For portions of gas piping that are regulated to a working pressure of less than 1/2 p.s.i,a 3-psi test with a diaphragm gauge that has a set hand and has a maximum range of six (6) p.s.i. is acceptable. Poly gas lines must be buried at least eighteen inches (18") below the ground with a copper tracer wire not less than 18 gauge.
