Perform Residential Plumbing Rough-In Inspection using eAuditor

A Residential Plumbing Rough-In Inspection is a critical evaluation conducted during the early stages of residential construction, before walls, floors, and ceilings are closed. It focuses on verifying that the plumbing system—pipes, fittings, drains, vents, and water supply lines—is properly installed, aligned, and compliant with building codes.

Performing a Residential Plumbing Rough-In Inspection using eAuditor ensures a thorough, structured, and digital evaluation of a home’s plumbing system during the early construction phase. This inspection focuses on verifying the correct installation of supply lines, drainage systems, vents, and pipe supports before walls, floors, or ceilings are closed, enabling early detection of defects, compliance verification, and proper documentation.

1. Introduction to Residential Plumbing Rough-In Inspection

1.1 Purpose of the Inspection

The inspection aims to:

• Ensure proper installation of all plumbing components including water supply, drains, vents, and fixture connections.
• Detect potential leaks, misalignments, or code violations before finishing construction.
• Verify that pipe materials, sizing, and layouts comply with local plumbing codes and design specifications.
• Provide digital documentation for accountability, follow-up, and continuous improvement.

1.2 Importance of Rough-In Inspection

• Correct early-stage installation prevents future water damage, leaks, or drainage problems.
• Confirms pipe slopes and venting for proper flow and ventilation.
• Supports efficient fixture installation, avoiding rework or modifications.
• Ensures code compliance, protecting homeowners and contractors from regulatory issues.

2. Preparation Before Inspection

Proper preparation ensures the inspection is safe, thorough, and efficient.

  • Water supply line inspection (hot/cold)
  • DWV system inspection
  • Pipe support and anchoring
  • Fixture rough-in verification
  • Venting and slope checks
  • Pressure or leak testing
  • Photos, notes, and corrective recommendations
• Enable photo and video attachment fields and digital signature verification.

2.4 Gather Tools and Equipment

• PPE: helmet, gloves, goggles, safety boots.
• Tools: tape measure, level, slope gauge, flashlight, pipe inspection mirrors.
• Testing equipment: water pressure gauge, air test kit for DWV.
• Digital device: tablet or smartphone with eAuditor installed.

2.5 Safety Planning

• Identify hazard zones, including areas with exposed piping or elevated platforms.
• Confirm emergency procedures, including access to first aid and safe exits.
• Assign roles for monitoring safety and ensuring adherence to PPE protocols.

3. Water Supply Line Inspection

3.1 Material Verification

• Confirm pipes are made of approved materials (PEX, CPVC, copper, or approved alternatives).
• Verify correct pipe diameters per design specifications for each fixture.

3.2 Installation and Alignment

• Ensure pipes are routed according to design plans and avoid interference with electrical or structural components.
• Check connections, fittings, and joints for proper assembly and seal.

3.3 Pipe Supports and Anchorage

• Verify pipe hangers, straps, and supports are correctly installed at recommended intervals.
• Ensure pipes are secure, straight, and free from sagging.

3.4 Pressure Testing

• Conduct preliminary water pressure tests to identify leaks or weak joints.
• Document results in eAuditor for corrective action.

4. Drain, Waste, and Vent (DWV) System Inspection

4.1 Pipe Slope and Alignment

• Confirm drains have adequate slope (typically 1/4 inch per foot for horizontal runs).
• Check for proper alignment to prevent clogs and maintain smooth drainage.

4.2 Vent Stack Verification

• Ensure vent pipes are correctly installed to allow proper airflow and prevent sewer gas buildup.
• Verify vent connections to main stacks meet code requirements.

4.3 Fixture Rough-In

• Confirm drain, supply, and vent locations match planned fixture positions.
• Verify spacing, height, and alignment for sinks, toilets, showers, and tubs.

4.4 Cleanouts and Accessibility

• Ensure cleanouts are installed for maintenance and future access.
• Verify accessibility and location per code requirements.

5. Hazard Identification

• Inspect for sharp edges, exposed joints, or potential leaks.
• Check for interference with structural framing, electrical wiring, or HVAC ducts.
• Identify any non-compliant materials or installation techniques.
• Log all hazards in eAuditor with priority levels for corrective action.

6. Documentation in eAuditor

• Record every observation: location, component, issue type, severity, and recommendations.
• Attach photos or videos for visual verification.
• Assign responsible personnel and target dates for corrective actions.
• Maintain a digital audit trail for regulatory compliance and future reference.

7. Post-Inspection Actions

7.1 Report Generation

• Generate a comprehensive digital report summarizing:
  • Water supply line inspection
  • DWV system evaluation
  • Fixture rough-in verification
  • Identified hazards and corrective recommendations
  • Supporting photos and videos

7.2 Task Assignment

• Assign corrective actions to qualified personnel with materials, methods, and deadlines.
• Schedule follow-up inspections to ensure compliance and effectiveness.

7.3 Continuous Monitoring

• Compare results with previous inspections or design plans to track recurring issues.
• Update inspection frequency and maintenance plans based on findings.

8. Benefits of Using eAuditor

• Structured workflow ensures all components are systematically inspected.
• Digital documentation reduces errors and preserves records.
• Real-time reporting enables immediate action on defects.
• Photo/video evidence supports verification and audits.
• Task tracking improves accountability and timely resolution.
