If you’ve suddenly lost hot water or noticed your system isn’t performing like it used to, you’re not alone. In Richardson, TX and surrounding areas like Allen, Plano, Garland, and Lake Highland, homeowners face water heater problems every year—especially with our rapidly changing climate and aging infrastructure. Whether it’s a traditional or tankless water heater, a small issue can quickly grow into a costly plumbing repair. Fortunately, at Casto Leak Detection, we’re here to help diagnose, repair, and replace your system with the care and attention you deserve.
Key Takeaway:
Water heater failure can stem from several causes, including sediment buildup, leaks, aging parts, or faulty installation. Acting quickly with professional support can restore comfort, reduce energy waste, and prevent further damage.
Common Reasons Why Your Water Heater Might Be Failing
Sediment and Mineral Buildup
One of the most frequent culprits in Richardson and surrounding cities like Frisco and Rowlett is sediment buildup in the tank. Over time, calcium and magnesium in hard water settle at the bottom of the tank, forming a thick layer that reduces heating efficiency and accelerates tank corrosion. This is especially common in older systems or homes without a proper water filter.
In areas like Wylie and Sachse, where hard water is common, regular maintenance like flushing the tank can greatly extend your unit’s lifespan. Our water heater repair and installation services include detailed system inspections to clear out mineral deposits safely and effectively.
Internal Corrosion and Rust
If your water heater is over eight years old, internal rust could be eating away at your system. This is often detected through discolored water or metallic odors. For tankless systems, this could mean corrosion at the heating elements themselves. Regular water heater maintenance is essential to catch corrosion early and prevent leaks or full system failure.
Aging water heaters in Addison and North Dallas are especially vulnerable, especially in homes with outdated plumbing materials. Installing a new tankless water heater may be a more efficient, long-term solution.
Undetected Leaks
Leaks are a silent threat to water heaters, whether from pressure valves, fittings, or hidden joints. Left unchecked, they can lead to full tank bursts, structural damage, and mold growth. That’s why we always recommend leak detection services for anyone experiencing inconsistent water temperatures or increased utility bills.
In neighborhoods across Garland, Rowlett, and Plano, we’ve found that early plumbing leak detection can save homeowners hundreds in repair costs and potential insurance claims.
What You Can Do Right Now
Schedule a Diagnostic Inspection
When your water heater starts acting up, one of the best things you can do is schedule a professional inspection. Our team at Casto Leak Detection in Richardson performs thorough diagnostics to identify not just the symptoms, but the root cause of your system’s issues. Whether it’s slab leak detection or a faulty thermostat, we use advanced tools like electronic leak detection and thermal imaging to pinpoint the problem.
Evaluate Repair vs. Replacement
In areas like Allen and Frisco, where many homes are reaching the 20–30-year mark, it’s common for residents to ask: should I repair or replace? If your water heater is under warranty or has isolated issues, a quick water heater repair may suffice. However, if the unit is nearing the end of its lifespan or has suffered from repeated issues, installing a new water heater is often more cost-effective.
We help our clients weigh water heater installation cost against energy savings, warranty coverage, and household water usage.
Consider a Tankless Upgrade
Tankless water heater systems offer higher energy efficiency and virtually endless hot water. These are increasingly popular in places like North Dallas and Lake Highland, where homeowners are upgrading to eco-friendly, modern systems. If your current water heater can’t meet your household’s demands, a tankless water heater installation may be the perfect solution.
Preventive Measures to Keep Your Water Heater in Top Shape
Flush the System Regularly
To prevent mineral buildup, it’s essential to flush your system once or twice a year, especially in mineral-rich areas like Wylie and Richardson. This improves performance, increases efficiency, and prevents long-term damage to the heating elements.
Our licensed plumbers can safely perform system flushes as part of routine general plumbing repairs, ensuring your unit stays clean and efficient.
Inspect Pressure Relief Valves
Faulty or leaky pressure relief valves are a common cause of hidden leaks. Left unchecked, these can lead to slab leak repair issues in older homes across Addison and Garland. We recommend checking your valves during every annual service to prevent overpressurization or tank failure.
Monitor Your Hot Water Usage
Heavy or sudden usage spikes can overwhelm older systems, particularly in large homes in Plano and Allen. If your household size has grown or you’re remodeling, consider a larger-capacity water heater or consult with us for a more energy-efficient hot water system installation.

Answering Common Questions
How long should a water heater last in Richardson, TX?
Traditional water heaters typically last 8–12 years, while tankless models may last up to 20 years with proper maintenance. Hard water and lack of maintenance can shorten this lifespan.
What are signs I need water heater repair?
Look for inconsistent temperatures, rusty water, strange noises, or visible leaks. These are signs that your unit may require hot water heater repair.
Is it better to repair or replace an old water heater?
If your system is over 10 years old and experiencing recurring problems, replacement may be more cost-effective. We help homeowners assess water heater installation cost and energy savings when deciding.
The Impact of Plumbing on System Longevity
Your water heater’s lifespan heavily depends on the integrity of your plumbing. Corroded pipes, improper drain installation, and neglected leaks can strain your water heater and lead to premature failure. Maintaining healthy plumbing ensures consistent pressure, cleaner water, and extended appliance life.
Why Drain Health Matters for Water Heaters
Your drains play a vital role in safely removing excess water and condensation from your heater. Blocked or aging drains can back up into the unit, leading to mechanical damage. Our drain cleaning and jetting service helps keep your entire system clear and running smoothly.
