Water Heater Maintenance - The Home Depot

Connect a standard garden hose to the water heater drain outlet near the base. Place the other end of the hose near a floor drain or in a large bucket. Draining a water heater will take between 20 and 25 minutes total. Flush sediment from the bottom of the heater by opening the drain spigot and allowing the water to flow until it runs clear.

5.9 Conductivity | Monitoring & Assessment | US EPA

Caustic attack on boilers is a localized attack due to extremely high pH (12.9 +). It can take two forms: caustic gouging or caustic cracking, also called caustic embrittlement. Caustic attack or caustic corrosion, is often encountered in phosphate treated boilers in which deposits of phosphates or other 'scale' occur in high …
