Vertical cast iron soil pipe must be supported at not more than 10-foot intervals, with additional support at base and each floor penetration. Horizontal spacing differs and depends on pipe size. Proper support prevents joint separation, vibration, and excessive load on couplings. Journeyman exams emphasize these spacing values since failure to follow them results in unsafe installations and code violations.

Pressure loss due to elevation = 70 × 0.433 = 30.3 psi. Subtracting from 65 psi = 34.7 psi (≈ 35.7 psi). Journeyman exams test this because multistory plumbing design must account for elevation losses. Without accurate calculation, fixtures may not meet minimum required pressures.

Vertical copper tubing must be supported at its base and at each floor level. Journeyman exams test this because improper vertical support can cause pipe settlement and joint failure.

A scupper is an opening through a parapet or wall to drain roof water to the exterior. They act as primary or secondary overflows. Journeyman exams include scupper questions to test storm drainage terminology.

The most critical precaution is having a fire extinguisher nearby, as sparks and flame can ignite combustible materials. OSHA and fire safety standards require hot work permits, protective barriers, and fire watch when open flames are used. Journeyman exams test safety practices to ensure plumbers prioritize fire protection during cutting and welding operations.
