Water Heater Repair & Installation in Addison
No hot water in Addison, TX? Same-day tank & tankless install by licensed plumbers. Free estimates, upfront pricing. Call (831) 290-4327 today.
Water heater repair and installation in Addison starts with an honest diagnosis: if the tank is under 8 years old and the failure is a $150 thermocouple or heating element, we repair. If it is 10+ years, rusting at the base, or a cracked tank, replacement is cheaper than a repair that will fail again in six months. Belt Line Plumbing stocks 40, 50, 75, and 80-gallon tanks plus the top tankless brands on our trucks — most Addison installs finish same-day.
Cold showers in Addison hit hardest in January. When your water heater fails, you need the fix today — not a 3-day wait for parts. Belt Line Plumbing stocks tank heaters in 40, 50, 75, and 80 gallon sizes plus the top tankless brands on our trucks, so most Addison water heater replacements finish same day. We service every make: Rheem, A.O. Smith, Bradford White, Rinnai, Navien, Noritz, and the builder-grade tanks common in 1970s Belt Line townhomes.
Signs your water heater is failing
- No hot water, or hot water that runs out in 5 minutes
- Rusty or brown hot water (usually the tank interior, not the city supply)
- Popping or rumbling sounds during heat cycles — mineral scale on the burner
- Water pooling under the tank, or a rusted drip pan
- Pilot light will not stay lit on a gas unit
- Tankless unit throws error codes or shuts down mid-shower
- Tank is 10+ years old (average Dallas-water lifespan is 8–12 years)
What's included with our water heater repair & installation
Every water heater repair & installation job with Belt Line Plumbing includes the deliverables below — quoted flat, in writing, before we start.
How we repair & install water heaters
- 1Same-day diagnosisA licensed plumber checks the burner, thermocouple/igniter, gas valve, T&P valve, anode rod, and tank shell. Most repairs are decided in 20 minutes.
- 2Repair vs. replace, honest mathIf your tank is under 8 years old and the failure is a $150 thermocouple, we repair. If it is 12 years old with a rusted anode and a leak at the base, replacing is cheaper than a repair that will fail again in six months.
- 3Right-sized replacementA family of four in a 1970s Addison townhome does not need the same tank as a five-bath Highland Park estate. We size to actual demand, code, and gas-line capacity — not to what will maximize a ticket.
- 4Code-compliant installEvery install includes a new expansion tank (Addison code), proper T&P discharge, seismic strapping where required, drip pan, and disposal of your old unit. We pull permits when required and hand you the paperwork.
- 5Tankless — done rightTankless conversions in Addison usually need a gas-line upsize, dedicated venting, and softened water (Dallas hard water eats tankless heat exchangers). We tell you up-front what the real cost is.
What drives the price
Every job we do is flat-quoted before we start — no hourly meter. The factors below determine what your specific number will be:
- Tank size (40 vs 50 vs 75+ gallons)
- Gas vs. electric
- Tank vs. tankless (tankless install adds gas & venting work)
- Whether the existing setup meets current code — earthquake strap, expansion tank, pan
- Location (attic install is more labor than a garage)
- Removal & disposal of the old unit (always included in our quote)

Why an Addison-local team matters
Dallas Water Utilities supplies hard water — 8–11 grains per gallon — that lays down calcium scale inside every tank in Addison. Without an annual flush, a 12-year tank life becomes 7. If we install a new heater and you also add a softener, we drop $50 off the softener install. It saves you a heater in year 9.
