When your water heater stops working or starts showing signs of age, it's more than just an inconvenience - it affects your daily comfort and your family's access to hot water for bathing, cleaning, and cooking. If you're a homeowner in Lewisville, TX facing a failing water heater, understanding your replacement options and what the process involves can help you make the right decision for your home. At Mack's Plumbing, TX LLC, we've been helping families throughout the North Texas area make informed choices about their water heater systems for years, and we're here to guide you through every step of the replacement process.
Water heaters typically last 8-12 years depending on usage, water quality, and maintenance. If yours is approaching or exceeding that age, or if you're experiencing rust-colored water, strange noises, leaks, or inconsistent temperatures, replacement might be the most practical solution. The good news is that today's water heater options are more efficient and reliable than ever before, giving you the opportunity to upgrade to a system that fits both your family's needs and your budget.
Understanding Your Water Heater Replacement Options
When it comes time to replace your water heater in Lewisville, you'll encounter two primary categories: traditional tank water heaters and modern tankless systems. Each has distinct advantages and considerations worth exploring.
Traditional Tank Water Heaters
Tank water heaters are the most common choice in North Texas homes. These systems heat and maintain a large reservoir of water, typically ranging from 40 to 80 gallons, ready for immediate use whenever you need hot water.
The advantages of tank systems include:
- Lower upfront cost compared to tankless options
- Simple installation process that usually takes 2-4 hours
- Familiar technology that most plumbers can service easily
- Ability to provide large amounts of hot water simultaneously for multiple uses
- Straightforward replacement without major home modifications
However, tank systems do have some drawbacks:
- Continuous energy use to maintain water temperature even when not in use
- Limited hot water supply if your household uses multiple hot water sources at once
- Takes up significant space in your utility room or basement
- Higher water heating costs over the system's lifetime
- Risk of tank corrosion and leaks after 10-12 years
Tankless Water Heater Systems
Tankless water heaters heat water on-demand as it flows through the unit, providing hot water without maintaining a storage tank. These systems have become increasingly popular among homeowners looking to reduce energy consumption.
The benefits of tankless systems include:
- Significantly lower energy bills - up to 30% more efficient than tank systems
- Unlimited hot water supply as long as the unit's flow capacity matches your demand
- Compact design that requires minimal space
- Longer lifespan, typically 15-20 years with proper maintenance
- No risk of tank rupture or water damage from tank failure
- Better resale value appeal for many home buyers
The considerations with tankless systems include:
- Higher initial purchase and installation cost
- Requires gas line assessment and potentially upgraded gas service
- Requires adequate ventilation for proper operation
- Slightly longer wait time for hot water to reach your fixtures
- May need water softening if you have hard water in Lewisville
- More complex repairs that require specialized technician expertise
Assessing Your Home and Sizing Your New System
One of the most important steps in water heater replacement is determining the right size for your household. This isn't a one-size-fits-all situation - your needs depend on how many people live in your home, how many hot water fixtures you use simultaneously, and your daily hot water usage patterns.
For tank water heaters, sizing is based on the "first-hour rating" - how much hot water the system can deliver in the first hour of use. A family of four typically needs a 50 to 60-gallon tank, while a family of six may require 75 to 80 gallons. Using a tank that's too small means running out of hot water during peak usage times like morning showers and evening dishes. Using a tank that's too large wastes energy and takes up unnecessary space.
For tankless systems, sizing is based on the "gallons per minute" (GPM) requirement at your peak hot water demand. If you're running a shower and washing dishes simultaneously, for example, a smaller unit may struggle to provide adequate hot water to both. Most households in the Lewisville area require 8-10 GPM for comfortable simultaneous usage.
During your water heater replacement, the technicians at Mack's Plumbing, TX LLC will assess your home's hot water needs by understanding your household size, usage patterns, and the number of hot water outlets you typically use at once. This tailored approach ensures you're not paying for more capacity than you need, while guaranteeing your family won't experience uncomfortable temperature fluctuations or running out of hot water.
Energy Efficiency Considerations for North Texas Homes
The Texas climate, particularly in the Lewisville area, offers some unique advantages when it comes to water heating. Our mild winters mean your water heater won't need to work as hard during the cold months compared to northern climates. However, that also means you have an excellent opportunity to take advantage of high-efficiency models that can deliver significant savings year-round.
Energy-efficient water heaters can reduce your monthly utility bills substantially. A high-efficiency tank model might use 10-15% less energy than standard units, while tankless systems can save 25-30% or more. Over the lifespan of your water heater, those savings add up considerably.
When evaluating energy efficiency, look for the Energy Guide label on any new water heater. This label shows the estimated yearly energy cost and compares it to similar models. Higher-efficiency systems have higher upfront costs, but the long-term savings often justify the investment, especially if you plan to stay in your Lewisville home for many years.
Heat pump water heaters represent another emerging efficient option, using electricity more efficiently by pulling ambient heat from the surrounding air. Solar water heaters can also be considered in North Texas, where sunny days are plentiful, though these typically require a conventional backup system for cloudy periods and winter months.
Permits, Codes, and Compliance in Lewisville
Water heater replacement in Lewisville, TX requires adherence to local building codes and permit requirements. While this might sound like extra paperwork, these regulations exist to ensure your new system operates safely and efficiently.
Most water heater replacements in Lewisville require a permit from the city. This process involves:
- Submitting installation plans to the building department
- Having a licensed plumber perform the work according to code specifications
- Scheduling a final inspection before the system is activated
- Receiving sign-off from the city inspector
Specific code requirements in Lewisville address:
- Proper ventilation for gas-fired water heaters
- Temperature and pressure relief valve installation and venting
- Earthquake straps or bracing to secure the unit (important in Texas homes)
- Gas line sizing and installation standards
- Electrical requirements for electric water heater models
- Proper drainage and pan installation to protect against leaks
At Mack's Plumbing, TX LLC, we handle the permit process as part of our service. We understand Lewisville's specific requirements and ensure your new water heater installation meets all local codes. This protects you from potential fines, ensures your system operates safely, and maintains your home's insurance coverage.
The Water Heater Replacement Process
Understanding what happens during your water heater replacement helps you prepare for the service and know what to expect.
Day of Installation - Step by Step
The morning of your appointment, our technician will arrive with all necessary equipment and materials. The entire process typically takes 3-5 hours, depending on your specific situation and the type of system being installed.
First, the technician will turn off the water and gas supplies to your current water heater. They'll allow the system to cool slightly before proceeding - hot water can cause serious burns, so safety is always our priority. You'll notice we take this seriously in every interaction, just like our customers appreciate when we remove our shoes before entering your home and take care to protect your property.
Next, the technician will drain your old water heater completely. This water is directed safely into a floor drain or through appropriate routing to avoid damage. This step is crucial and takes patience - a 50-gallon tank holds significant water.
Once drained, the plumbing connections are disconnected from the old unit. This includes the cold water inlet, hot water outlet, and gas or electrical connections. The old tank is then carefully removed from its location. Water heaters are heavy - typically 100-150 pounds when empty - so proper lifting techniques and equipment prevent injury and property damage.
The installation area is then cleaned and inspected. Any necessary adjustments to the rough plumbing or gas lines are made at this point to ensure your new system fits properly and operates at peak efficiency.
Your new water heater is positioned in the space, and all connections are made according to code specifications. Gas lines are tested with a pressure gauge to ensure no leaks. Water supply lines are connected with appropriate shut-off valves. A temperature and pressure relief valve is installed with proper venting. For gas units, the vent pipe is secured and inspected.
Once all connections are complete, the system is filled with water slowly to check for any leaks at connection points. The gas or electrical supply is restored, and the unit is fired up for initial testing. The technician will monitor the system's operation, verify proper heating function, and confirm water temperature reaches appropriate levels.
Finally, the technician explains how to operate your new system, demonstrates the location of shut-off valves and the relief valve, and reviews any specific features or settings relevant to your new equipment.
Removal and Disposal of Your Old Water Heater
Proper disposal of your old water heater is part of responsible service. At Mack's Plumbing, TX LLC, we remove your old unit as part of the installation process and dispose of it appropriately.
Old water heaters contain materials that require proper handling. The metal tank can be recycled, and any remaining sediment or minerals are handled in compliance with environmental standards. We don't leave the disposal to you - it's included as part of our comprehensive replacement service.
Depending on the condition of your old unit, it may be hauled to a recycling center where metals are recovered and reused. This approach protects the environment while recovering valuable materials. Some older units may require special handling if they contain specific components, but this is rare in standard residential systems.
Understanding Warranties and Guarantees
When you invest in a new water heater, understanding your warranty coverage provides peace of mind. Most new water heaters come with manufacturer warranties that typically cover:
- Tank defects for 6-12 years (depending on the model and manufacturer)
- Parts and components for 1-3 years
- Labor coverage varies by manufacturer and is sometimes available through extended warranty programs
Tankless water heaters often carry longer warranties - many manufacturers offer 10-15 year coverage on the heat exchanger, which is the most critical component.
At Mack's Plumbing, TX LLC, we stand behind our work with a 100% guarantee on repairs. When we install your new water heater, we ensure everything is done correctly from the start. Our state license (License #M-39290) and insurance backing give you assurance that your installation meets all professional standards.
Ask your technician about extended warranty options when they present your equipment choices. Some manufacturers offer plans that cover parts and labor beyond the standard warranty period, which can provide valuable protection over the system's lifespan.
Timeline and What to Expect
Water heater replacement is typically a same-day service for most homes in Lewisville. Here's what the timeline generally looks like:
- Initial assessment and equipment selection: 20-30 minutes
- Disconnection of old system: 20-30 minutes
- Removal of old unit: 15-20 minutes
- Installation of new system: 45-60 minutes
- Testing and verification: 20-30 minutes
- Cleanup and explanation: 15-20 minutes
Total time: approximately 3-5 hours depending on your specific situation
Some situations may extend the timeline slightly:
- If your old unit has corroded connections that require extra time to disconnect safely
- If upgrades to your gas line or venting are necessary to meet current code
- If the new system requires modifications to fit in your space
- If we discover related plumbing issues during the assessment
We'll provide you with a clear timeline before work begins, and our technicians maintain professional communication throughout the process. Unlike some service providers, we focus on doing the job right rather than rushing through it.

Post-Installation Care and Maintenance
Once your new water heater is installed and operating, proper maintenance helps maximize its lifespan and efficiency.
For tank systems, annual maintenance includes:
- Flushing the tank to remove sediment buildup, which improves efficiency and extends tank life
- Inspecting the anode rod, a sacrificial metal component that prevents rust, and replacing it if significantly corroded
- Testing the temperature and pressure relief valve to ensure it operates properly
- Checking all connections for leaks or corrosion
For tankless systems, maintenance includes:
- Periodic descaling if your Lewisville area water has mineral hardness, which keeps the heat exchanger clean and efficient
- Annual professional inspection of all components
- Checking gas connections and venting for any obstructions
- Verifying proper water pressure and flow rates
Many homeowners benefit from annual maintenance plans that ensure their water heater receives proper attention. Regular maintenance catches small issues before they become major problems, saving money and extending system life.
