What does flushing a water heater do, and how often?

Flushing drains the sediment that settles to the bottom of the tank. That sediment is what causes popping noises during heating, lower efficiency, and eventual tank corrosion. Annual flushing extends tank life noticeably in Atlanta water. We can do it as a standalone service or as part of an annual plumbing check.

Will you haul away my old water heater?

Yes. Old units leave with us at the end of the install and go to a metal recycler. Disposal is included in the flat-rate quote.

Are your water heater installations permitted?

Yes. Water heater replacements require a plumbing permit in most Metro Atlanta jurisdictions (and a gas permit when applicable). We pull the permit, complete the install to code (T&P discharge, expansion tank, drip pan, venting, seismic strapping where required), and schedule the inspection. The permit fee is included in the written quote.

Atlanta Water Heater Service: Everything Your Home Needs

Full-service water heater repair and installation for Metro Atlanta homes and businesses, available 24 hours a day, 7 days a week.

Reliable, Licensed Atlanta Water Heater Service, Available Around the Clock

Our background-checked Atlanta water heater technicians arrive on time, diagnose before they quote, and back every job with a warranty. No surprise charges. No shortcuts. Just honest water heater service from a company Metro Atlanta homeowners have trusted since 1974.

Atlanta water has a moderate mineral content that hits water heaters in predictable ways. Tank water heaters typically last 8 to 12 years. After about year 8, the failure pattern starts: sediment buildup, popping noises during heating, rust-colored hot water, a slow drip from the tank bottom, or a complete leak. We diagnose accurately and tell you whether repair is the right call or replacement makes more sense.

Every job is flat-rate quoted in writing. No hourly meter, no overtime charges on emergencies. Financing is available on replacement work. We pull permits where required and coordinate the county inspection. Old tanks leave with us. Licensed in Georgia (J102723 / MP209550). Family owned since 1974.

We Service Water Heaters Others Replace

Our licensed Atlanta technicians diagnose the real problem before quoting, so you do not pay to replace a tank that just needs an element or a thermostat.

How Atlanta Water Heater Service Works

01

Diagnose

We start with the safe homeowner checks, then run a real diagnostic. Electric units get heating element and thermostat tests. Gas units get a pilot, thermocouple, and gas valve check.

02

Recommend

A unit under 8 to 10 years old with a clear failure is usually a worthwhile repair. A unit over 10 years old with multiple problems is usually a better candidate for replacement. You decide.

03

Install

Most repairs are same-day with parts from the truck. Most replacements are same-day or next-day. We pull the permit, register the manufacturer warranty in your name, and haul the old tank away.

Water Heater Frequently Asked Questions

Everything you need to know about water heater service and plumbing services at Delta Plumbing.

How long should a water heater last in Atlanta?

A traditional tank water heater typically lasts 8 to 12 years in Metro Atlanta. Tankless typically lasts 20 plus years. Atlanta’s water has enough mineral content that sediment builds up in tanks over time, which is the biggest single factor in tank failure. Annual draining and flushing extends tank life. Skipping that maintenance shortens it.

My water heater is leaking from the bottom. What now?

If the leak is from the tank itself (not the fittings, drain valve, or T&P), the tank has failed and needs replacement. Tank bottoms corrode from the inside out and there is no patch that lasts. Shut off the water supply at the cold inlet, turn off the gas or electric, and call us. Most full replacements can be same-day.

Why is my hot water rust-colored?

Two possibilities. The anode rod inside the tank is depleted and the steel tank is starting to corrode. Or, the cold-side supply line has rust coming through from the city main. We isolate which one by running hot and cold separately. Anode rod replacement is a relatively cheap repair if caught in time. Tank corrosion past the anode usually means replacement.

Should I repair my water heater or replace it?

Under 8 years old with a clear component failure (heating element, thermostat, thermocouple, gas valve): repair almost always makes sense. Over 10 years old, leaking from the tank, or rust-colored hot water: replacement is usually the better call. Between 8 and 10 years, it depends on what is failing and the cost of the repair compared to the cost of a new install. We give you the math, you decide.

How much does a new water heater installed cost?

Most residential tank water heater replacements (40 to 50 gallon, gas or electric, standard install) fall in the low to mid four figures all-in, including the tank, install, permit, and disposal of the old unit. Tankless replacement costs more upfront but lasts longer. Hybrid heat pump water heaters cost more upfront and earn it back in energy savings. We quote the all-in number in writing before we start.

Can you replace my tank water heater the same day?

Most of the time, yes. We carry the most common sizes (40 and 50 gallon, gas and electric) on the truck, and we can usually pick up the rest from a local supplier the same day. Same-day replacement is the norm, not the exception, on standard residential units.

What size water heater do I need?

Family size and number of bathrooms drive the answer. A two-person household with one bathroom is usually fine with a 30 or 40 gallon. A four-person household with two bathrooms typically needs a 40 to 50 gallon. Larger homes or homes with soaker tubs benefit from 65 to 75 gallon. For homes that frequently run out of hot water, tankless or a high-recovery tank is usually a better answer than a bigger tank.

Does my water heater really need an expansion tank?

If your home has a check valve, backflow preventer, or pressure reducing valve (PRV) at the main, which most Atlanta-area homes built in the last 30 years do, then yes. The expansion tank gives heated water somewhere to expand into without spiking pressure across the whole system. It protects the water heater, the T&P valve, and the supply lines. Code typically requires one on new installs.

Are hybrid heat pump water heaters worth it?

For Atlanta homeowners with a garage or unconditioned basement installation, yes, often. Hybrid units use 60 to 70 percent less electricity than a standard electric tank. The upfront cost is higher and they make some noise (like a small dehumidifier), but the energy savings and rebate programs make the math compelling for many homes. We can run the numbers based on your real usage and electric rate.
