What customers say about Water Heaters

  • “Brandenburg Plumbing provided excellent service diagnosing and repairing a water leak for one of my trusted seller clients. The issue was identified quickly, clearly explained, and resolved properly by replacing the leaking valve. Efficient, professional, and done right the first time. Lucas, the owner and master plumber, sets a high standard. His expertise, professionalism, and leadership are evident throughout the process. He takes a methodical, no-nonsense approach and prioritizes quality workmanship. The entire team was professional and respectful, and communication was smooth from start to finish. An honorable mention to Nick McBride, an outstanding journeyman plumber whose skill, attention to detail, and professionalism stood out. For context, I am Chris Cabiya, Founder and Principal Realtor® at Cabiya Realty Group and a local real estate investor serving the Highland Lakes area, including Marble Falls, Horseshoe Bay, and Granite Shoals. I hold service providers to very high standards on behalf of my clients. Brandenburg Plumbing met those standards without hesitation. Highly recommended.”

  • “I purchased a toilet with bidet seat and the bidet seat was not staying in place. Plumbers came back several times to adjust, but it still was not staying in place. Lucas Brandenburg came by to see it first hand and discovered a design flaw. He immediately ordered a different brand to replace it and it was installed several days later. I truly appreciate the owner of the company taking my concerns seriously and coming out personally to diagnose the problem! The plumbers are all incredibly nice and knowledgeable and everyone was focused on fixing the issue. I am happy to endorse a hometown company with such great customer service @”

Water heater questions we hear most

Find answers to common plumbing and HVAC questions from our expert team.

That noise is most likely caused by sediment and mineral scale that has built up at the bottom of your tank. As the burner heats the water, steam bubbles form underneath the sediment, and the noise you hear is the sound of those bubbles escaping. This buildup reduces efficiency and can lead to tank damage over time. It's a clear sign your water heater needs to be professionally flushed and inspected.

Yes. A leak from the bottom of the tank itself is a serious issue, typically indicating that the inner tank has corroded through. This is not repairable and is a sign of imminent failure that could lead to significant water damage. You should shut off the water and power supply to the heater and call us for an emergency replacement immediately.

We generally recommend considering replacement if your water heater is 8-12 years old or if the cost of the repair is more than 50% of the cost of a new unit. An older, less efficient unit may continue to have problems, while a new water heater will be more energy-efficient and come with a full manufacturer's warranty. We can provide an honest assessment to help you make the best financial decision.

Traditional tank water heaters typically last 8-12 years, while tankless models can last 15-20 years with proper maintenance. The lifespan depends on factors like water quality, maintenance frequency, and usage patterns. Regular flushing and anode rod replacement can significantly extend your unit's life.

Tankless water heaters provide endless hot water on demand, are more energy-efficient (saving 20-30% on energy costs), take up much less space, and last significantly longer than traditional tank models. They're ideal for families who frequently run out of hot water or want to reduce their energy bills.

A rotten egg smell typically indicates bacteria growth in the tank, often caused by a failing anode rod. Rusty or brown water suggests corrosion inside the tank. Both issues require immediate professional attention, as they can indicate serious problems that may lead to tank failure and water damage.

We recommend annual maintenance for traditional tank water heaters, which includes flushing sediment, checking the anode rod, testing the pressure relief valve, and inspecting all connections. Regular maintenance prevents breakdowns, improves efficiency, and extends the life of your unit.

For electric heaters, this usually means a tripped breaker or failed heating element. For gas heaters, it could be a pilot light issue, gas supply problem, or faulty thermocouple. Regardless of the type, a complete loss of hot water requires immediate professional diagnosis to restore service quickly.

Yes, we can relocate water heaters, though it requires careful planning for proper venting (gas units), electrical work, and plumbing modifications. We'll assess your space, ensure code compliance, and provide you with options that meet your needs and budget.

The right size depends on your household size and hot water usage patterns. For traditional tanks, we typically recommend 40-50 gallons for 1-3 people, 50-60 gallons for 3-4 people, and 60-80 gallons for larger families. For tankless units, we calculate based on flow rate and temperature rise needed. We'll help you choose the perfect size during our consultation.
