Signs It's Time to Replace Your Water Heater

Most tank water heaters last about 8–12 years. If yours is in that range and showing any of these signs, replacement is usually the smarter call than another repair:

Rusty or discolored hot water, or a metallic taste
Water pooling around the base of the tank (a leaking tank can't be repaired)
Popping or rumbling sounds from sediment buildup
Not enough hot water, or it runs cold quickly
The unit is 10+ years old and needing frequent fixes

Not sure whether to repair or replace? If the tank itself isn't leaking, it may be a fixable thermostat, element, or valve — see our water heater repair page, or just call and we'll give you an honest recommendation.

What are the advantages and disadvantages of tank water heaters?

Tank water heaters offer the advantage of a simple, straightforward design that provides a reliable supply of hot water. They are generally less expensive to purchase and install compared to tankless options. However, they have larger physical footprints and continuously heat water, leading to higher energy consumption and costs over time. Their capacity limits the amount of hot water available at once, and the tanks can suffer from sediment buildup and corrosion, shortening their lifespan compared to tankless models.

How long does it take to install a tank water heater?

A standard tank water heater replacement usually takes about 2–6 hours. A straightforward swap of a like-for-like unit is on the shorter end; jobs that require new venting, gas or electrical changes, code upgrades, or moving the heater take longer. Tankless installations typically run longer — see our tankless water heater services page.

How long do water heaters last?

Most tank water heaters last 8–12 years, and tankless units can last 20 or more with proper maintenance. Hard water shortens tank life by accelerating sediment buildup, so flushing the tank annually — or adding a water filtration system — helps your new heater last longer.

Should I get a gas or electric water heater?

Gas water heaters generally heat water faster and cost less to run where natural gas is available, while electric units have a lower upfront cost and are simpler to install. The best choice depends on your home's existing hookups and usage. We'll assess what you have and recommend the most cost-effective option.

What size water heater do I need?

For most households a 40- or 50-gallon tank is the sweet spot — roughly 40 gallons for 1–3 people and 50+ gallons for 4 or more, depending on how many bathrooms and appliances draw hot water at once. Larger or growing homes often benefit from a tankless unit. We'll size it to your actual usage so you're never short on hot water.

Our Water Heater Installation Process

A water heater looks simple, but a safe, code-compliant install is best left to a licensed plumber — and in Texas that means more than swapping a tank. When we install or replace your water heater, we:

Safely disconnect and haul away your old unit (gas or electric)
Set and level the new heater, with a drain pan and proper venting
Install a new temperature & pressure (T&P) relief valve and, where required, a thermal expansion tank to meet Texas code
Reconnect water, gas, or electrical the right way and check for leaks
Test the unit, set the temperature, and walk you through it before we leave

Doing it to code protects your home and your warranty — and it's the difference between a heater that lasts and a callback in six months.

Gas, Electric & Tankless Options

We install every common type of water heater and help you pick the right one for your home and budget:

Gas & electric tank heaters — the most common, cost-effective choice for most homes. If you're switching fuel types or need a new gas connection, we handle that too through our gas line services.
Tankless water heaters — endless hot water and lower energy bills, ideal for larger or growing households. Learn more on our tankless water heater services page.

Still deciding? Our team will size the unit to your household — most homes do well with a 40- or 50-gallon tank — and lay out the tradeoffs so you're not guessing.
