Quick answer
Plumber Service TX replaces gas and electric tank water heaters across Dallas–Fort Worth, typically same or next-day. Standard sizes are 40, 50 and 75 gallons; the flat-rate quote includes the unit, labor, required code items (drain pan, expansion tank, venting corrections), city permit and old-unit disposal.
When a Tank Is Simply the Right Call
Tankless gets the headlines, but a quality tank heater remains the sensible choice in plenty of situations: replacement budgets that need to stay predictable, homes without gas capacity for tankless, rental properties, and households whose usage never outruns 50 gallons. A well-installed tank with annual flushing delivers dependable hot water for a decade at the lowest upfront cost of any option.
The quality difference isn’t the tank brand as much as the installation. The failed installs we replace typically skipped the drain pan, the thermal expansion tank, or proper venting — all code items in DFW cities, all cheap at install time, all expensive after they cause damage.
What’s Included in Our Flat-Rate Tank Replacement
- The right-size unit: 40, 50 or 75-gallon, gas or electric, matched to your household’s recovery needs — not just whatever was there before.
- Code compliance: drain pan with routed drain line, thermal expansion tank, seismic strapping where required, venting corrections, and a proper shut-off valve.
- City permit and inspection: pulled and scheduled by us in Fort Worth, Arlington, Frisco, Southlake and surrounding municipalities.
- Haul-away and cleanup: your old unit leaves with us; the work area is left cleaner than we found it.
- Warranty registration: manufacturer tank warranty registered in your name plus our written workmanship warranty.
Stretch the Next Tank’s Life in Hard-Water Country
Two habits meaningfully extend tank life in DFW: an annual flush to clear scale before it hardens into an insulating layer, and an anode rod check around year four — the sacrificial rod corrodes so the tank doesn’t, and replacing a consumed rod is the cheapest tank-life extension there is. Ask your installer to set both reminders; we build them into our maintenance scheduling.

Tank Water Heaters — Frequently Asked Questions
How long does a tank water heater installation take?
A standard like-for-like swap runs 2–4 hours including code updates. Attic installations, fuel-type changes or relocations take longer; your written quote states the expected duration before we start.
What size tank water heater does my family need?
As a rule: 40 gallons suits 1–3 people, 50 gallons fits 3–4, and 75 gallons serves 5+ or homes with large soaking tubs. Recovery rate matters too — gas recovers roughly twice as fast as standard electric — so we match both numbers to your household.
Gas or electric tank — which is better?
If you have gas service, gas usually wins: faster recovery and lower operating cost in Texas. Electric is simpler and fits homes without gas; heat-pump electric models cut operating costs dramatically but need space and airflow. We quote what fits your house.
Do I really need an expansion tank?
In most DFW cities, yes — code requires one on closed systems (which check-valved municipal connections create). Without it, thermal expansion spikes pressure with every heating cycle, stressing the tank seam and relief valve. It’s included in our standard install.
Why is my hot water rusty or smelly?
Rust-tinted hot water usually means the anode rod is consumed and the tank interior is corroding; a rotten-egg smell is sulfur bacteria reacting with the rod. Both are diagnosable — sometimes a rod swap fixes it; a rusting tank body means replacement time.
Can I replace a 40-gallon with a 50-gallon in the same spot?
Usually yes — modern 50s often match old 40-gallon footprints, though attic and closet installs need clearance and pan-size checks. Send photos of your space and current unit label and we’ll confirm in the emailed quote.
Is a leaking tank dangerous or just messy?
Tank-body leaks only get worse and can dump 50 gallons plus a continuous feed if the shut-off fails. Close the cold inlet valve above the heater, set gas units to ‘off,’ and email us marked URGENT — same-day replacement is usually possible.
Do you install customer-purchased water heaters?
We prefer to supply the unit — it lets us warranty the whole job and stand behind both parts and labor. If you’ve already purchased one, email the model details and we’ll advise honestly whether we can install and warranty it.
