Hiram grew from about 1,400 residents in 2000 to nearly 5,000 in 2020, so many water heaters here came in with new construction and are now aging out. Building and plumbing permits for Hiram go through Paulding County's Building and Permitting Division in Dallas. Call the number on this page to be connected with a local plumber in Hiram.

Signs your heater should be replaced
- A slow drip or puddle from the bottom of the tank
- Rust-colored hot water or a metallic smell
- Popping from sediment as the tank heats
- Hot water that runs out sooner than it used to
- Moisture around the relief valve or top fittings on an older unit
- A label showing the tank is past ten years old
Local conditions in Hiram
Hiram's median home was built in 2004, though about 24.8% of homes predate 1980. Newer subdivisions usually have the heater in a garage or attic; older houses closer to the original town may have tighter closets and older fittings.
Water is split by area. The City of Hiram provides water in and around downtown, and Paulding County Water System serves the rest. Paulding County's water comes from Richland Creek Reservoir plus treated water bought from the Cobb County-Marietta Water Authority; its 2024 report shows free chlorine disinfection and no violations, and does not state hardness. Sewer is Paulding County's, and parts of the area are not on municipal sewer.
Permits are not issued by the city. Hiram sends building permits to Paulding County, whose Building and Permitting Division issues plumbing permits from 240 Constitution Blvd in Dallas; inspections are scheduled at 770-505-1398.
Atlanta Gas Light is the regional pipe utility; check your bill to confirm. If you smell gas, leave first, then call 911 and Atlanta Gas Light at 877.427.4321 from a safe place.
What affects the cost
- Gas, electric, tankless or heat pump
- Tank size and recovery rate
- Garage versus attic installation
- Pan, drain, relief line and expansion tank needs
- Venting and gas connector condition
- County permit and old-tank removal
What happens when you call
An independent plumber who serves Hiram picks up. They will ask what the heater is doing, its fuel, size and location, and walk you through shutting it down if it is leaking. They then check the setup in person and price the job, including the Paulding County permit. If your household has grown since the house was built, ask whether a larger tank or a faster-recovering model would serve you better than a same-size swap.
