Do I need a permit for water heater replacement in Town of Mansfield?
Yes. In Connecticut, water heater replacement generally requires a permit, and Town of Mansfield is no exception.
The Connecticut code requires a permit to replace any plumbing, gas, or mechanical system, and water heater replacement is not on the exempt list (CSBC R105.1 and R105.2). Connecticut amends the relief valve discharge rule so the pipe ends not more than 6 inches above the floor or waste receptor (CSBC P2804.6.1). An owner may do electrical, plumbing, heating, cooling, and solar work in a single-family home the owner occupies or will occupy without a trade license, but the work still needs inspection and approval by the building official (CGS 20-340(11)); the exemption does not cover two-family homes or rentals. Where a backflow preventer may be affected, the building official must notify the water company, and the permit waits on any cross-connection correction (CSBC R105.3.1.4).
