"They were able to come out the same day. I talked to their firm and not a call service which was refreshing. I thought their price was reasonable. He was able to fix it that day and very polite and professional. as a comparison when I called the plumber, I used to use. I got a call center who were answering for multiple firms and they scheduled an appointment for me two days out that was the earliest they said they could get to me. But then I got a call back from the actual FIRM"

With 9 years of experience, Texas Drain Specialist is the company you need to take care of your home or business. We offer quality work at an affordable rate. Give Texas Drain Specialist a call today! If you've had someone else cable your clogged line and you still had a clog, call us! We have all the tools and equipment to clear any stoppage. Not only that, but we make sure you know why the clog occurred and a solution to keep the clogs away. If you know you have roots in your line, we are the company to call. We have a camera to show the condition of the entire sewer line, so an informed decision can be made about how best to tackle the problem. Looking to purchase a new home? Call us to schedule a camera inspection - see for yourself the condition of the pipes under the house and out to the street/septic before you close. This is especially important if the house was built prior to 1960, before PVC became the norm.

"They told me it would cost 175 for clearing the clog. The worker came over and told me that rather use the camera since his snake tool was deep inside his van. He told me that the camera would cost me 225. I felt cheated by this since I did not ask for the camera but was forced upon by the worker. Bad practice. He had the snake which he did not want to use since he would make 175 and not 225. Sleazy"

FAQs for tankless water heater installation projects in Round Rock, TX

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.
