Professional Water Heater Services

Pro Plumbing Services offers fast and reliable water heater service in Marietta, GA.  Most commonly, we see older water heaters that are well past their useful service life. In this case, we install new water heaters. We are happy to make suggestions and even bring the new unit to the home for you.  In some cases if you have new unit on hand, we can install that water heater for you.

Sometimes the water heater isn’t that old, it’s just had a single part fail.  In the case of parts failing, we can often replace the compromised part and get you back up and running the same day. That’s part of our water heat repair service.  Anytime we are repairing a water heater that still has life left, we recommend a complete water heater maintenance service.  This includes a water heater flush, examination of critical components, installation of any replacement parts, refill, and relighting your pilot light (in the case of gas units).

5 Signs You Need Water Heater Repair in Marietta, GA

Most homeowners don’t think about their water heater until it stops working. That’s normal — it’s a tank in a closet or basement, quietly doing its job for years. But water heaters rarely fail all at once. They usually drop hints first. Catch them early and you’re looking at a simple repair. Miss them, and you’re looking at a flooded utility closet, a ruined subfloor, or a full replacement bill you weren’t expecting.

Here’s what to watch for.

Water Around the Tank

Puddles at the base of your water heater are never nothing. Sometimes it’s just a loose fitting or a valve that needs tightening — an easy fix. Other times it’s the tank itself, cracked from the inside where you can’t see it, slowly weeping until it isn’t slow anymore. Either way, standing water means it’s time to call someone, not wait and check again next week.

Rust Stains

Rust on the tank, on the connections, or in your actual hot water is a sign the metal is breaking down from the inside. A little discoloration once might be nothing. Rust that keeps showing up? That’s corrosion working its way through the tank wall. Once a tank starts rusting internally, repair windows close fast.

Wet Drywall

If the wall or ceiling near your water heater feels soft, looks discolored, or has that faint musty smell, you’ve likely got a slow leak that’s been going on longer than you realize. Drywall doesn’t get wet from nothing. This one’s worth acting on quickly — the longer it sits, the more it costs, and the more likely you are dealing with mold on top of the leak itself.

Low Hot Water

Showers going cold faster than they used to, or the water never quite getting hot in the first place — that’s usually a heating element or thermostat issue, and it’s one of the most common calls we get from Marietta homeowners. Sediment buildup at the bottom of the tank causes this too, especially in areas with harder water. The fix is often straightforward, but ignoring it just means colder showers and a harder-working (more expensive) unit.

Dripping Sounds

Hear a faint dripping, hissing, or ticking coming from the water heater? Don’t write it off. Pressure relief valves failing, small leaks in fittings, or a tank under pressure it shouldn’t be — these all make noise before they make a mess. If it wasn’t making that sound six months ago, something’s changed.

The Bottom Line

None of these signs mean disaster on their own. But together, or ignored long enough, they turn a $150 repair into a $1,500 replacement. If you’re noticing water pooling, rust, soft drywall, weak hot water, or strange sounds from your unit, get it looked at.

Should You Repair or Replace Your Water Heater?

Once you’ve spotted a problem, the next question is usually the harder one: is this worth fixing, or is it time for a new unit? A few concrete factors settle that question more often than not.

Age of the Unit

Tank water heaters typically last 8 to 12 years. Tankless units run longer, often 15 to 20. If yours is past that window, repair usually just delays the inevitable. You’re paying to patch something that’s already close to the end of its life.

Cost of Repair vs. Cost of Replacement

A common rule of thumb: if the repair costs more than half the price of a new unit, replace instead. A $200 thermostat fix on a 4-year-old heater is an easy repair. A $600 fix on a 10-year-old tank when a new one runs $1,200 to $1,800 installed is replacement territory.

What’s Actually Failing

Some issues are cheap and isolated, like a heating element, a thermostat, or a pressure relief valve. Others are structural. A corroded or leaking tank can’t be repaired. Once the tank itself is compromised, it’s a replacement, full stop, regardless of age.

Frequency of Repairs

One repair in five years is normal wear. Two or three repairs in the last year is a pattern. The unit is failing faster than fixes can keep up with.

Efficiency and Utility Costs

Older units lose efficiency as they age, especially with sediment buildup. A new unit, particularly if you upgrade to tankless or a higher-efficiency tank, can meaningfully lower monthly energy costs. If your bill has crept up and the unit is older, that’s part of the math too, not just the repair invoice.

Household Demand Changes

If your hot water needs have grown (more people in the house, an added bathroom), an aging unit that was already borderline may not be worth repairing into a system that’s now undersized anyway.

Warranty Status

Worth checking before anything else. If the unit is still under manufacturer warranty, repair costs might be partially or fully covered, which tips the math heavily toward repair even on a unit that’s a few years old.

The Bottom Line

Young unit, isolated fixable issue: repair. Old unit, tank-level failure, climbing repair frequency: replace. Everything else falls in the gray zone between those two, where cost comparison and repair history usually make the decision for you.

Water Heater Brands We Work With in Marietta, GA

Not all water heaters are built the same, and after years of repairs and installs across Marietta and the surrounding area, we’ve got a pretty clear read on which brands hold up, which ones tend to need more attention, and what homeowners should expect from each. Here’s an honest rundown.

Rheem

Rheem is probably the brand we see most often in Marietta homes, and for good reason. It’s a solid, dependable mid-range option with parts that are easy to source, which keeps repair costs down and turnaround times fast. We don’t see many surprise failures with Rheem. When something does go wrong, it’s usually a straightforward fix: a thermostat, an element, a valve. Good choice if you want reliability without paying a premium.

A.O. Smith

A.O. Smith tends to run a notch above Rheem in build quality, especially in their higher-tier residential lines. Tanks are well insulated, components last, and the company backs its units with strong warranties. We’ve replaced fewer A.O. Smith tanks due to internal corrosion than almost any other brand on this list. If longevity is your priority, this one’s worth the extra cost.

Bradford White

Bradford White is a favorite among plumbers and installers, and once you’ve worked on enough of them, you understand why. These units are built heavy duty, sold mostly through professional channels rather than big box stores, and the components inside are genuinely higher grade. Repairs are less frequent, but when parts are needed, they’re not always sitting on a shelf, so turnaround can take a day or two longer. Worth it for the extra durability.

State

State Water Heaters (part of the same parent company as A.O. Smith) is a dependable, no-frills option. Quality sits close to Rheem, solid and consistent, without a lot of flashy features. We don’t have complaints about State units. They do what they’re supposed to do, and repairs tend to be routine when they’re needed at all.

Navien

Navien is one of the stronger names in tankless. Their condensing technology runs efficiently, and the units hold up well when properly maintained, which is the key phrase. Tankless systems in general need regular flushing to prevent scale buildup, and Navien units are no exception. Homeowners who stay on top of maintenance rarely call us for anything beyond routine service. Those who skip it tend to see heat exchanger issues down the line.

Rinnai

Rinnai is the other major player in tankless, and it’s a genuine toss-up between Rinnai and Navien depending on the specific model and install. Rinnai units are known for being a little more forgiving with harder water and slightly easier to service in our experience, though both brands are well engineered. If you’re going tankless, either one is a good call. The bigger factor is usually proper sizing and installation, not brand.

The Bottom Line

For standard tank water heaters, Rheem, A.O. Smith, Bradford White, and State are all solid choices, with A.O. Smith and Bradford White generally edging ahead on build quality and longevity. For tankless, Navien and Rinnai are the two names worth considering, and maintenance matters more than which of the two you pick.

Whatever brand you have, or whatever you’re thinking about installing, we can help you make the right call.

Types of Water Heaters We Service

Tank vs. Tankless: Pros and Cons

Since brand only matters once you’ve picked a type, it’s worth breaking down how tank and tankless actually compare.

Tank Water Heaters

Pros

• Lower upfront cost, usually half the price of tankless once installed
• Simpler installation, which also keeps labor costs down
• Repairs are generally cheaper and parts are easier to find
• Familiar technology that most plumbers can service without specialty training

Cons

• Shorter lifespan, typically 8 to 12 years
• Standby heat loss means you’re paying to keep water hot even when you’re not using it
• Limited hot water supply. Run a big enough load of laundry and a couple of showers back to back and you can run out
• Takes up more physical space, usually a closet or utility room

Tankless Water Heaters

Pros

• Longer lifespan, often 15 to 20 years with proper maintenance
• Endless hot water on demand, no more waiting for the tank to recover
• Higher energy efficiency since there’s no standby heat loss
• Compact size, mounts on a wall and frees up closet space

Cons

• Higher upfront cost, both for the unit and installation, which sometimes requires upgraded gas lines or electrical
• Requires regular maintenance, particularly flushing to prevent scale buildup, or performance drops over time
• Repairs can be more expensive when they’re needed, and not every plumber is equipped to service them
• Output can be limited during simultaneous high demand, like two showers and a dishwasher running at once, unless sized correctly

The Bottom Line

Tank water heaters make sense if you want a lower upfront cost and don’t mind replacing the unit more often. Tankless makes sense if you’re staying in the home long term, want lower energy bills, and are willing to keep up with maintenance. Either way, correct sizing and a good installation matter more than the type you choose.
