"Eco Flo Plumbing spent a lot of time preparing an estimate for me. The company also made two visits to my home for thorough inspections of my job site. The price quoted to me was fair and reasonable, and the sales person was extremely personable! I Wholeheartedly Recommend EcoFlow !"

"We had a lot of fixtures to replace, each with a different challenge. I asked for quality products and Cliff delivered with American Made Prier Plumbing and PEX piping. I explained the details and he was on the job the next day. He gave me the estimate and it seemed fair. When he was done, everything looked great and worked perfectly. Cliff is easy to work with and will deliver what you specified. When he was done, he cleaned up the job sites completely. The final bill matched the estimate. No hidden charges. I would hire him again for any plumbing problems in the future. I would recommend him to everyone."

Came promptly at appointment  time

Completed the hot water heater flush and set the temperature for me.

Checked all plumbing connections and made recommendations about what was good and what needed attention

Gave me a written estimate of what recommended repairs would cost if I chose to do them.

No pressure from them to do them now.

Very courteous and pleasant.

"Richie,  Mike and their crew did a Oil to Gas conversion at my home. They replaced the boiler and hot water heater. They also removed and took away everything including the oil tank. They did an excellent job. This company are experts at what they do. As far as I know they only do Oil to gas conversions. Everything went smoothly, and everything was completed in one day as promised. I have no complaints. Mike and Richie were easy to deal with. They answered all my questions and did everything I requested. It was 10 degrees the day they did my job,  and it was difficult for them to work, but nobody complained and just did a great job. Their price was better than all the other estimates I got, but I choose  them because I was most comfortable with the answers they gave to my questions. It is also nice to deal with the owner and not some salesman you will never see again once you sign the paperwork.   IF YOU ARE DOING AN OIL TO GAS CONVERSION LOOK NO FURTHER!

"Since this was an emergency (we were concerned that the pipe might crack with no support) we went with Universe as that was the first company we contacted. The service manager (Tommy) sent over a tech (Nick) within 2 hours. Nick proceeded to remove 20ft of old pipe and replaced with new PVC and new support straps. The job took about 5 hours including the assessment and cleanup. The service was performed very professionally. We did pay $2,700, which we feel was a quite high for 5 hours of work. But, since we didn't get competing bids we can't complain."

FAQs for gas piping projects in Danbury, CT

Plumbers with proper licensing and credentials install and relocate gas lines. When hiring a professional, verify they have experience with gas systems and all required certifications. Some homeowners choose to work with plumbers specializing in natural gas installations, as they have extensive experience with similar projects and understand the safety requirements.

The timeline for gas line relocation varies based on project complexity, permit processing, and inspection scheduling. The physical labor takes a few hours to one day, depending on the line length. However, the actual installation work represents only part of the overall project timeline. Your contractor should provide a specific timeframe based on your circumstances and local permitting requirements.

Your gas supply must be shut off during the relocation process. This safety measure prevents gas leaks while connections are being modified. Plan for this temporary service interruption by making alternative arrangements for cooking, heating, or other gas-dependent systems in your home. The shut-off generally only lasts for a portion of the work, often a few hours.

Relocating gas lines to connect new appliances is a common reason for this type of project. Whether you're installing a gas stove, fireplace, dryer, or outdoor grill, a professional can determine the best route for extending your existing gas system. The cost will depend on the distance between your current gas line and the new appliance location.

Gas line work is not suitable for DIY projects. Natural gas is highly flammable and potentially lethal if not handled correctly. Gas leaks can be difficult to detect without specialized equipment. Professional plumbers have the proper training, tools, and experience to safely relocate gas lines while ensuring compliance with local building codes and safety standards.
