CR Plumbing is your locally owned and operated plumbing company. We get the job done right the first time. We are known for getting the job done promptly, correctly and at reasonable prices. We serve the commercial, industrial, and residential sectors. Our capabilities include restaurants, retail, tenant improvements, repairs, residential new construction and remodels, service and maintenance .

"This review will sound like I was paid to write it, and I was not. Promise! I am just that impressed. I am completely blown away! In a nervous, and frantic panic I called CR Plumbing to get some help. I have never had to call a plumber before. My drain was backed up and flooded my laundry room. It was a disaster. I called and spoke with Autumn, she automatically calmed me down. She was very quick getting all of my information, and getting an appointment set up. She had a way to calm a crazy, panicked, stressed mom out. Her customer service was outstanding as well. Autumn thank you for everything. Within a FEW hours Nick and Nathan were out to my home to fix this huge headache of a mess. I am not kidding, within not even 20 minutes they had it fixed and everything working great! We are a home with an immunocompromised kiddo, they offered to wear booties or take their shoes off, and wore masks. They didn't even have to ask me if I wanted them to wear the masks. As a family who is very worried about germs, they sure did make sure to make us feel comfortable and safe. They even went above and beyond to state they were not sick or experiencing any sickness symptoms. Like REALLY, that was amazing. Nick and Nathan made sure to answer all of my questions, and make sure everything was up and working. They even offered to ziptie my washer drain thing, and take out the towels to the trash that were wet. I did not let them but they offered. Where do you get this customer service? I surely have never had someone let alone a company have this amazing customer service. CR Plumbing, you guys have won my business and will be the only ones we will ever use! You guys are amazing, and I am so grateful I bumped into your company on google. You will forever be our favorite and go to. Autumn, Nick, and Nathan (You are the only ones I spoke with) You guys seriously have made such a huge difference in our lives, with your kindness, professionalism, quick service, and patience. I am sure the rest of the team is just as great. The world needs more people like you guys, and more companies that truly understand customer service like you guys do. Thank you again!"

"All went well. The licensed technician came out within 24 hrs.

The cost of fixing was around $1k, so bought a new affordable smaller Whirlpool with warranty. I highly recommend Appliance Repair Now for their customer service, knowledge, and honesty. Thank you."

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.
