Common water heater installation issues in Swansea
Permit and code compliance
Illinois requires a permit for water heater installation, and work must meet the Illinois Plumbing Code. Failure to pull a permit can lead to fines and issues during home sale.
Expansion tank requirements
On closed water systems, an expansion tank is required by code to prevent pressure buildup. This adds to the installation cost and must be installed on the cold supply line.
Cold inlet water temperature
Swansea's cold winters mean incoming water is very cold, which can reduce a water heater's recovery rate. A properly sized unit is needed to meet household demand.
