Dallas homes are young, with a median build year of 2002, so tankless water heaters generally go in without much rework. Water may come from the City of Dallas or Paulding County depending on the address, and the city issues plumbing permits inside its limits. Call the number on this page to be connected with a local plumber in Dallas.

After you call
The number on this page puts you in touch with an independent plumber who works in Paulding County. The first conversation covers your current heater, fuel type, the number of bathrooms and whether the house is inside Dallas city limits. For an installed tankless unit that is misbehaving, have the error code ready, along with the date it was last flushed if you know it. A visit usually covers the gas line, vent route and a spot for the condensate drain.
What moves the price
- Upsizing the gas line from the meter, since tankless burners need far more gas at peak
- Vent length and where it exits
- Condensing or non-condensing unit
- Recirculation for long runs to a far bath
- Moving the heater to a new wall
- The city or county plumbing permit
Dallas conditions
Dallas grew fast; its population roughly tripled between 2000 and 2020, and only about 17% of homes predate 1980. Newer garages and basements make wall-mounting and venting fairly simple. Homes near the historic downtown are older and may need more work, such as a new vent path because the old flue cannot serve a sealed unit. In bigger two-story houses on the edges of town, the main design question is often recirculation, so hot water reaches an upstairs bathroom far from the garage without a long wait.
Water is split by address. The City of Dallas runs about 37 miles of lines serving around 2,650 customers in its water service area, buying water from Paulding County Water System and disinfecting it with free chlorine. Other Dallas-area addresses are on Paulding County water directly. The city's report does not state hardness, so a test is the way to set descaling intervals.
Community Development issues plumbing permits for properties inside city limits, with inspections handled through the city (770-443-8110 ext. 1203). Outside the city, Paulding County issues permits. Atlanta Gas Light owns the gas pipes; confirm the pipe utility on your gas bill. If you smell gas, leave first, then call 911 and AGL at 877.427.4321 from a safe place.
Short checklist
- Know whether your water bill comes from the city or the county
- Have a gas bill nearby
- Clear access to the heater and the meter
- Note the heater's age and capacity from its label
