"Due to pinholes in our 1980 home copper pipe system we needed a complete re-pipe done. Contracted with Plumbing Express. At 9 a.m. four of their specialists went to work with protecting our floors then got busy opening walls and removing the copper pipes. They were all friendly and professional and worked well together. By 6 p.m. we were back in business with all new cpvc piping and our home tidied back up. Our home has 3 bathrooms and the usual appliances and sinks and everything was working when they departed. Impressive! A couple days later their sheetrock guy came out and patched the walls and ceilings and matched the stippling perfectly in the ceiling. They delivered as advertised. I highly recommend Plumbing Express."

Roto-Rooter is America's Largest Plumbing and Drain Cleanng Company. We offer 24 hour services with no overtime or after hour charges. We also offer convenient finance options

"BUYER BEWARE! Had a pipe leak within my wall. Caught it fairly early with minimum damage. The Roto Rooter rep Brian came out and inspected and said I needed water mitigation based off the moisture in my walls. When I say the leak wasn't that bad, it really wasn't! He stated that my insurance company would cover it all and that he deals with my particular company all the time and not to worry. I obviously was taken back by the cost of almost 4k! Fast forward, my insurance company are questioning duplicate charges and Roto-Rooter is saying I owe almost 3k or a lien will be placed on my property! This whole water mitigation is a scam and the salesman did not tell the truth. They should have picked up their fans a lot earlier than they did. I'm sure they were trying to milk all the money they could. Over 5k for a bunch of fans in my home. I WILL NEVER REFER ANYONE TO THIS PLACE! Contacting my lawyer and will have my day in court if necessary. BUNCH OF SCAM ARTISTS IF YOU ASK ME!"

"$80 service call and a 500% markup on parts? That’s excessive. I completely understand that businesses need to make a profit, but being charged over $500 for a 20-minute visit is more than what many highly skilled professionals—attorneys included—earn for their time. Before scheduling the service, I asked for a quote on both the part and labor. Unfortunately, I was told they couldn't provide that information in advance (which, in hindsight, should’ve been a red flag). I trusted the positive reviews and moved forward anyway. When the technician arrived, they spent about five minutes confirming what we already knew: that we needed a specific part. We expressed concern about the cost, and a manager offered a modest discount, which we declined. We ended up paying the $80 just to be told exactly what we had already suspected. Afterward, we contacted another company that provided the part at cost ($100) and completed the service for $135. Bottom line: if you're trying to avoid unnecessary expenses--which I think right now most people are, it’s worth calling around. I’d recommend saving yourself the service call fee and going with a company that’s more transparent from the start- one that respects your time and your wallet."

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.
