We have built our reputation for excellence repiping homes the Atlanta area. Call on us to locate and address your pipe problems. In addition to our whole home repipe services, Plumbing Express services our client's needs throughout their home by offering comprehensive home plumbing services including: water heater service and upgrade to Rinnai tankless and Rheem tank hot water systems. We will also take care of your clogged drains and broken sewer pipes.

"Due to pinholes in our 1980 home copper pipe system we needed a complete re-pipe done. Contracted with Plumbing Express. At 9 a.m. four of their specialists went to work with protecting our floors then got busy opening walls and removing the copper pipes. They were all friendly and professional and worked well together. By 6 p.m. we were back in business with all new cpvc piping and our home tidied back up. Our home has 3 bathrooms and the usual appliances and sinks and everything was working when they departed. Impressive! A couple days later their sheetrock guy came out and patched the walls and ceilings and matched the stippling perfectly in the ceiling. They delivered as advertised. I highly recommend Plumbing Express."

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
