Pipe material, sizing, fittings, and fixture branches match the approved system
Critical itemThe selected system should support demand, pressure, temperature, compatibility, and local requirements.
A pre-cover whole-house repipe checklist for approved material and sizing, fixture branches, manifolds and shutoffs, support and expansion, protection plates, fireblocking, insulation and freeze protection, pressure and leak testing, abandoned piping, grounding implications, permits, and comprehensive as-built photographs.
6 items to check
The selected system should support demand, pressure, temperature, compatibility, and local requirements.
The owner should be able to isolate serviceable areas and avoid unnecessary stagnation or delay.
Clamps, sleeves, bend radius, expansion loops, and isolation should follow the system instructions.
Piping should be protected from future fasteners and environmental damage while required assemblies are restored.
New work should pass the applicable test before concealment and old piping should not create hidden cross-connections or leaks.
Future owners and trades should be able to locate concealed piping.
Use after new supply piping is installed and tested but before walls, ceilings, floors, insulation, or cabinets conceal it. Do not enter contaminated, structurally unsafe, energized, confined, or oxygen-deficient areas; do not open pressurized systems or handle sewage. Use qualified plumbing, electrical, remediation, environmental, and structural professionals where applicable.
A residential water-service checklist for main shutoff replacement, pressure-reducing valve orientation and setting, bypass and strainer conditions, pressure testing, thermal expansion control, meter and utility boundaries, supports, accessibility, labeling, leak checks, and owner emergency operation.
A restoration hold-point checklist for source correction, water category and hazards, material removal, containment, cleaning, structural and electrical safety, moisture mapping, drying equipment, daily records, hidden cavities, HVAC contamination, dry-standard comparison, odor and visible contamination, and authorization before drywall, cabinets, insulation, paint, or flooring are replaced.
A pre-startup residential water-heater checklist for correct fuel and capacity, location and clearances, pan and drainage, thermal expansion, temperature and pressure relief discharge, venting or combustion air, electrical or gas connection, seismic or structural support, piping, shutoffs, permits, and leak readiness.
