We are Miami's favorite plumber has been our label for a while Vleyz Plumbing services is a customer focused plumbing company Located in Miami FL we employ highly trained plumbers whose goal is to make our company the best service company in the Miami area. We are prepared for projects and equipment replacement

"Do not hire this company. If there’s an issue after they do the work, more than likely you won’t heard or see them again. In a nutshell they unresponsive and unprofessional to say the least. I Don’t want to make this too lengthy so I’m keeping it as short as possible so that you know what my issues are with this company. Samuel (one of the 2 plumbers said to fix the charge will be $1,200. I said I’ll get more quotes he then agreed to $800 for a job that took less than 1 hour. I hired them to repair a leak on my main water line on 11/28/2024. I called my water company on 12/16/24 to confirm if the water consumption was back to normal and they told me no. They can see live daily what’s going on. Samuel thinks a bill 30 later is the only way to know if the leak is still present and this is not the case. I’m sure they know this as well. Technology is a beautiful thing. I explained to Samuel in a voice mail and text that the water company is on the line with me now and will let him know the leaks has not been fixed. I sent several text and voice mails about the on going leak and for them to come back to fix asap. The representative agreed that we can do a conference call with the plumber. He did not answer my call or text. I was ghosted/received the silent treatment. My last voice mail and text messages to him was 1/2/25. No replies or call backs. I filed a complaint to Angie on 12/16/24 and the Plumber company had until 12/26/24 to reply and they did not. How ironic my last text and voicemail must have prompted them to now reply to Angi regarding my complaint. I said Just want you to know I just left you a detailed message about the leak and that I consider this abandonment of service from you if I don’t hear from you today You were pay in full, so there’s no reason why you should not complete this job. That’s why I’m calling this abandonment of Service which is unethical on your part. As a business and employee/r you never disregard your customers concerns which I have expressed to you. And nevertheless you never showed up, returned my previous calls/text. The. Suddenly they replied back on 1/2/2025 on the same day of my last text and voicemail Angi previously known as Home Advisors. As of today I have not hear from anyone from this company. They do not honor their 90 day working guarantee. I needed them to come back 2 weeks later and to be on a quick call with the water company . To his credit I did speak to Samuel for a very brief moment the first time a call..he was quite dismissive so I could not fully explain to much in our minute or less phone call. He told me he wouldn’t come back until January 2025. I texted and called 1/2/25 with details to come fix the leak. No answer from my voicemail or text messages."

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.
