A leaking water heater won’t fix itself — and every hour it sits, the risk of water damage grows. Delta Home Services responds same-day to leaking water heaters throughout Phoenix. Our licensed plumbers arrive, diagnose the source of the leak, and tell you honestly whether it’s a repairable fitting or a tank that needs to go. We carry replacement units on our trucks, so in most cases we can resolve the problem in a single visit.
Do This Right Now While You Wait
If your water heater is actively leaking, take these steps immediately to limit damage before our plumber arrives:
1. Shut off the cold water supply — The shutoff valve is on the cold water inlet pipe
at the top of the tank. Turn it clockwise to stop water feeding the leak.
2. Cut the power or gas — For electric heaters, flip the breaker. For gas, turn the
gas valve to the “pilot” position or off entirely.
3. Contain the water — Place towels or a bucket around the base. If water is near
electrical outlets or flooring, move what you can.
4. Call us — (623) 240-9892. We offer 24/7 emergency response and same-day service
throughout Phoenix.
Do not attempt to drain the tank or remove components yourself — a water heater under pressure can be dangerous. Let our licensed plumber handle it.
What's Causing the Leak? We'll Tell You in Minutes.
Not every water heater leak means replacement. Our plumber will diagnose the exact source on arrival and give you a straight answer.
- Usually Repairable
- Loose or corroded inlet/outlet connection at the top
- Faulty temperature & pressure (T&P) relief valve
- Loose or worn drain valve at the bottom
- Condensation mistaken for a leak (common in summer)
- Leaking pipe fitting above the unit
- Usually Requires Replacement
- Rust or corrosion on the tank body
- Leak from the bottom of the tank (internal corrosion)
- Tank age 10+ years with repeated issues
- Cracked or ruptured tank
- Multiple failing components on an older unit
We’ll never recommend replacement if a repair will do the job. But if the tank has failed, we’ll tell you clearly — and in most cases we can have a new unit installed the same day.
If Replacement Is Needed
If our plumber determines the tank needs to go, we’ll walk you through your options on the spot — no pressure, no surprises. We stock professional-grade electric and gas units on our trucks and can complete most replacements the same day.

Frequently Asked Questions — Leaking Water Heater Phoenix
Why is my water heater leaking from the bottom?
Leaks from the bottom of a tank usually indicate internal corrosion and a failing tank — this typically means replacement is needed. However, it could also be a loose drain valve, which is repairable. Our plumber will distinguish between the two and tell you honestly which applies to your unit.
Why is my water heater leaking from the top?
Top leaks are usually from inlet/outlet connections, a faulty temperature and pressure (T&P) relief valve, or a loose pipe fitting. These are generally repairable without replacing the unit. However, a T&P valve that’s actively discharging can indicate dangerous pressure buildup — shut off your water heater and call us immediately if this occurs.
Is a leaking water heater an emergency?
It depends on severity. A drip from a loose fitting is urgent but not dangerous. A large leak, ruptured tank, or actively discharging T&P valve is an emergency — shut off the cold water supply to the heater and the gas or electricity, then call (623) 240-9892 immediately. Delaying can cause significant water damage.
Can a leaking water heater be repaired or does it need to be replaced?
Leaks from valves, fittings, and connections are typically repairable. Leaks from a corroded tank or cracked tank body require replacement — there is no durable fix for a failed tank. We’ll assess your unit honestly and only recommend replacement when it’s genuinely necessary.
How quickly can you respond to a leaking water heater in Phoenix?
We offer same-day service and 24/7 emergency response throughout the Phoenix metro. In most cases a licensed plumber can be at your home within 2–4 hours. If your tank has ruptured or you have active flooding, shut off the water supply first then call (623) 240-9892 immediately.
