Reliant gas lines is a natural gas service line repair or replacement company. I handle the buried portion of the service line from curb stop to meter and the buried house line if the meter is far away from the house. I do a good job at a fair price, am qualified for both Peoples Gas and Columbia Gas and fully insured. As a small owner operator business I can be flexible on scheduling as these types of problems tend to be emergencies. While in business for myself just a short time now I have over 15 years of experience in the natural gas industry involving repair and replacement of gas mains and service lines.

"Reliant Gas Lines arrived at my house quickly. They made all the repairs fast and efficiently. Matt and his crew were very respectful of me and my property. I would not hesitate to hire them again. Very highly recommended."

See website for additional phones. See website for additional service areas.

"Tuesday in June 2022, 4:03 PM Received a call from my wife, that our water had stopped while my son was in the shower. 4:14 PM Placed a call to Quality Water (QW) for Service. Keep in mind they are a "24 hour" service, is what they say. Customer Service (CS) said when asked, for service call charges normally is $135.00. After 4 PM is when premium rates kick in, which is $229.00 for service call (not per hour) to get back up plus parts and I said I was okay with that because I did not have water. LONG STORY SHORT: they called couldn't be out that night and put me off till next morning. They called next morning, all crew out on a big job and can't make it till tomorrow-24 hrs. service? When they did, the plumbing was way different and after they came back out to change it, again as I had before, they didn't do like I asked and leaks. Charged me $2395.00 to replace a switch & 22 gal. pressure tank - very high, but they had me over a barrel. Check the picture of the plumbing I found after they left - I trusted them for years and was shocked of how I found it when it simple came straight in down and over to the tank like a square Z to this? No written estimate or receipt, I had to call to ask for it. As a former service manager, I can tell you this service manager, Aaron did not handle this correctly at all. In pre court resolution now, and possible small claims to rectify. This from a customer that used this company for a couple decades, but first time for 911 services - no longer using unless this is cleared to satisfaction. Take my advise, don't call them for 911 services because they will rack you over the coals and are NOT true 24 hour service. There is a lot more bulleted points I could add, but won't. I am a patient person, but they blocked both my phone numbers and the owner never called to solve, only left a response on Google reviews to give him a call to resolve and want to keep their rave reviews. They have my number and if cared, could have this taken care of long ago. Unfortunately, small claims are next, if not cleared up very soon."

"First of all, I can can do plumbing myself, but it usually involves more than a day or two and multiple trips to one of the big box stores. Since the tub hardware was old and corroded, I didn't want to take a chance of making things worse, so I decided to call in a professional; that the toilet started leaking was a (happy) coincidence for me, so he or she could do that at the same time. I contacted TruPlumbing and Tom was dispatched for the job... he contacted me to set up a time and date for the service call and also gave me a quote and the option to buy my own parts for the job, telling me what was needed, Tom arrived on time and had both jobs completed in a few hours; he was very professional, covered his shoes so as not to track dirt into the house, and explained what all he had done. I would definitely recommend TruPlumbing and will use them in the future."

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
