Boevaag plumbing is locally owned and operated We currently have two master plumbers and one apprentice plumber.

"I am a 76 year old woman who lives alone. I have three bathrooms in my home and called Boevaag Plumbing to repair one of the toilets. The service on August 22, 2024, was a replaced fill valve and flapper and the cost was $195.00. As long as the plumber was already onsite, I asked him to look at a second toilet that I thought might also needed a new fill valve and flapper. The plumber confirmed that was needed and asked if I wanted him to go ahead and do the repair. I asked him to do so. I naively did not ask what that additional repair would cost and assumed it wouldn't be another $195 as he was already on site. The plumber was very nice and left my home in clean condition. On completion of the second repair, I received a bill of $390! I was speechless and just wrote out a check. I wrestled for a couple of weeks with whether or not to call just to communicate my thoughts. I decided to write it off and never make the same mistake again. Shortly after the repair, the second toilet was giving me some problem. I called Boevaag and Jeff came out, at no charge. He found a piece of plastic in the new part that he thought was the culprit. A few weeks later the same issue presented. On December 5, 2024, I called Boevaag and told them the issue had not been resolved. Joe said he would get back to me. I called again on December 13, 2024 because I had not heard from Joe, left a message and Joe texted back, "Yes, you are on our list. With this cold weather we have been backed way up." With Christmas and the new year coming up, I chose to wait to hear back. Today is January 6, 2025. As I have not heard back, I called and talked to Joe. Joe assumed Jeff had followed up and resolved the issue. As that is not the case, I offered to accept a $150 refund and I would hire someone else to fix the problem. Joe said he would talk with Jeff to get the problem fixed and he hung up. I know plumbing repair is expensive and I may be wrong, but I feel, as an older single woman, I was taken advantage of. Joe has no customer service etiquette. He is rude and condescending. NO....I would definitely not recommend Boevaag Plumbing."

FAQs for tankless water heater installation projects in South Saint Paul, MN

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.
