Water heater: anode, sediment and corrosion
Separate tank maintenance, sacrificial anode, sediment, odour and corrosion before replacing a water heater too early — or too late.
VERT / GREEN
Document age, model, water, noise and history without opening a pressurized tank.
JAUNE / YELLOW
Hard water, odour, sediment noise or a heavily consumed anode justify manufacturer-specific review.
ROUGE / RED
Tank leak, shell corrosion, abnormal relief device or flooded unit: stop as appropriate and replace/inspect.
Quick triage
What the professional checks
The plumber/technician reviews tank condition, anode where provided and accessible, sediment, T&P relief, connections, water and replacement strategy.

Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
Advanced diagnostics to cross-check
V16 connects water, soil, climate, safety, materials and seasonal use to existing projects.
Specialized diagnostics to verify
V18 connects systems that become costly or regulated when a primary project triggers them.
Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
Often-overlooked service interfaces
V26 connects systems that cross utility, plumbing, HVAC, envelope and metering boundaries.
Project risks and overlooked interfaces
V27 connects payment, water, envelope, ventilation and jobsite details that often create costly surprises.
Finish and service details to verify
V28 connects small details that become costly once finishes are closed.
Household safety and compliance details
V29 connects smaller risks that often fall between finishes, appliances, plumbing and local code.
Commissioning and everyday safety
V31 helps verify systems after work and document the values that make a home safer to operate.
