Plumbing, sewer, and water damage

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.

A focused heat-pump water-heater checklist for room volume and airflow, ducting where used, condensate, noise, structural support, electrical circuit, thermal expansion, relief discharge, controls, operating modes, commissioning, rebates, and owner handover before final acceptance.

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 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.

A pre-backfill sewer lateral checklist for permit and utility coordination, excavation safety, pipe material and diameter, bedding, slope and alignment, joints and transitions, cleanouts, building connection, testing or inspection, trench water, warning tape, restoration limits, and photographic evidence before the repair disappears underground.

A post-repair sewer camera checklist for correct line and access point, continuous video, footage and distance reference, pipe condition, joints and transitions, slope indicators, debris and roots, branch connections, repair limits, flow observation, written findings, and retained media before final acceptance.

A functional sump-system checklist for basin and cover, primary pump, check valve, float travel, electrical supply, alarm, battery backup, charger, secondary pump, discharge piping, freeze and backflow risk, exterior termination, high-water simulation, maintenance, and owner handover.

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.
