FAQs
Common questions
Who do you call for water heater repair in Scottsdale?
Call a licensed local plumber — not a handyman — because water heater work involves gas lines, pressure relief valves, venting and city permits. Dominick Plumbing is a family-owned, licensed Scottsdale plumber (AZ ROC #350819) with same-day water heater repair across Scottsdale, Paradise Valley, Phoenix and the rest of the Valley. Call (623) 323-4538.
How do you repair a water heater yourself, and when should you call a pro?
Safe DIY checks: confirm the breaker or gas valve is on, relight the pilot per the label, press the reset button on an electric unit's thermostat, and flush sediment from the tank annually. Call a licensed plumber immediately for any gas smell, water pooling around the tank, a leaking T&P relief valve, scorched wiring, or no hot water after the basics above — these involve gas, pressure or code-permitted work that isn't safe to DIY.
How much does water heater repair cost in Scottsdale?
Most water heater repairs in Scottsdale run $180–$650 depending on the part: thermocouple or pilot assembly $180–$320, heating element or thermostat $250–$450, gas valve $400–$650, T&P or expansion tank $220–$380. If repair costs exceed ~50% of replacement, we'll show you the math — a new 40–50 gal tank install runs $1,400–$2,400. Every quote is flat-rate and written before we start.
How much does water heater installation cost in Scottsdale?
Most standard 40–50 gallon tank water heater installations in Scottsdale run $1,400–$2,400 installed, including haul-away and permit. Tankless conversions typically range $3,800–$6,500 depending on gas line, venting and electrical work. We give you a flat, written quote before any work begins.
Do you offer same-day water heater repair in Scottsdale?
Yes — when our schedule allows, we repair or replace water heaters the same day across Scottsdale, Paradise Valley, Phoenix, Fountain Hills and the rest of the Valley. Call (623) 323-4538 to check today's availability.
Tank vs. tankless — which is right for an Arizona home?
Tankless units save space, last 20+ years and deliver endless hot water — ideal for larger Scottsdale homes. Traditional tanks are cheaper to install and simpler to service. Because of Scottsdale's hard water, we always recommend pairing either system with a softener to protect your investment.
How long does a water heater installation take?
Most tank-to-tank replacements take 2–4 hours start to finish. Tankless conversions usually take 6–8 hours because we have to upsize gas lines, run dedicated venting and add electrical.
Do you pull permits and meet Scottsdale code?
Always. Every water heater install is permitted, code-compliant, and includes seismic strapping, a drip pan, expansion tank, and a properly sized T&P discharge line.
Do you haul away my old water heater?
Yes. We remove and responsibly recycle your old unit as part of every Scottsdale water heater replacement — no extra charge.
What brands do you install?
We install and service Rheem, Bradford White, A.O. Smith, Rinnai, Navien and Noritz — both tank and tankless. We'll help you choose the right size and efficiency for your home.
Are you licensed and insured?
Yes — Arizona ROC #350819, fully bonded and insured. Family-owned and based right here in Scottsdale.
