"The Plumbing Bros are hands down the best in Borne and San Antonio. They have helped with numerous plumbing issues at my home. Grant and his team are always quick to respond, extremely knowledgeable and straightforward. All around good people. I cannot recommend them enough."

Matt - Customer

"I don't usually write reviews. I felt compelled to do so because of my service guy. His name is Paul R. He did an excellent job from start to finish. He was very competent and knowledgeable. He explained everything in layman's terms so that I felt comfortable. Looked me in the eye with sincerity. I appreciated that. What's funny is I didn't get the results that I was hoping for but, I believed every word that he told me."

Cheryl - Customer

"Paul and Erik saved the day when we had a plumbing disaster. Not only were they professional, but you could tell that they knew what they were doing. This company is five star and we highly recommend The Plumbing Bros."

Beth - Customer

"On top of providing us an entirely new plumbing solution for our kitchen remodel, Plumbing Bros also made additional recommendations for an RO system. They've done our water heaters and water softeners as well. Will never hesitate using Grant and his team."

Heactor Leal - Customer

"Great communication setting up the appointment and the notifications were right on. They arrived well within the appointment time and explained what needed to be done. The location of the clean out could not be located right off, so they did a work around until the clean out popped up. Their work was completed quickly, with no problems indicated. Both gentlemen, Grant and Gavin, were friendly and courteous. I hope that I never need a plumbing service again, but if I do, The Plumbing Bros will be a first call."

David George - Customer

"The Plumbing Brothers are awesome! Great service and quality, friendly and responsive. We have used them to resolve several plumbing issues and have been pleased each time. We highly recommend them and have referred several friends to utilize their expertise. Wonderful company and people!"

Know the Signs

Common Problems We Resolve

Tankless water heaters are highly efficient, but they are also sensitive to certain conditions—especially mineral-heavy water, fluctuating gas pressure, and improper maintenance. At The Plumbing Bros, we frequently diagnose tankless water heater problems including:

  • No hot water at all
  • Water that turns cold during use
  • Inconsistent temperatures
  • System overload when multiple fixtures are running
  • Error codes displayed on the unit
  • Reduced water pressure when hot water is in use
  • Scale buildup affecting performance
  • Strange noises from the unit

Many of these problems stem from scale accumulation inside the heat exchanger, which restricts water flow and reduces heating efficiency. Annual flushing is critical to prevent this issue.

​

When Should You Schedule a Tankless Water Heater Repair?

Because tankless units operate differently than traditional tanks, even small warning signs should not be ignored. If you notice delayed hot water, fluctuating temperatures, or visible error codes, it’s best to have the system inspected promptly.

Ignoring minor performance issues can lead to larger repairs, shortened system lifespan, or complete failure. Professional servicing ensures your tankless system continues delivering the energy efficiency and convenience it was designed to provide.

Prevent Water Heater Repairs with Ongoing Maintenance

Routine maintenance is especially important for tankless systems in Boerne due to mineral content in local water supplies.

Our preventative maintenance services include:

  • Professional descaling and system flushing
  • Inspection of burners and ignition systems
  • Cleaning air intake filters
  • Testing safety components
  • Checking gas pressure and ventilation
  • Performance optimization

With annual maintenance, most major tankless water heater issues can be avoided, extending the life of the system and maintaining manufacturer warranty requirements.
