"Robert and his crew were great. They were able to replace my rusty old drain pipes that had developed a hole in one pipe and replace them. The drain system works great and I appreciate the hard work and effort in just finding the parts needed for my almost 100 year old plumbing and getting the replacement parts installed quickly so I could use water again. Thank You Robert and the Facilities and Plumbing Crew!"

"Camilo and Luis are fantastic plumbers. I manage several vintage apartment properties and always use Camilo and Luis at Pinnacle Plumbing for our routine jobs such as faucet repair and replacements, clogged bathroom/kitchen drains, water heater and gas wall heater replacement. One of the biggest jobs that we had to do was a complete sewer pipe replacement underground of our large vintage Victorian building. This involved excavating through the foundation and under the sidewalks to repair and replace sewer pipes that connect to the City sewage laterals. Luis and Camilo did a wonderful job of not only making the replacements and repairs, but we’re very empathetic to not disturb the tenants, with a focus on safety and good customer experience. They coordinated the entire large project from getting the permits to supervising the other subcontractors who had to excavate through concrete and also replace the concrete upon the jobs conclusion. You’ll be in good hands with Pinnacle! 👍🏼"

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.
