Best Sewer Line Cleaned in Dallas TX

A tankless water heater was purchased from 3G Plumbing and installed by them. The water heater failed city inspection 3 times before approval by the inspector. The inspection required a larger gas meter, several gas regulators, and exhaust vent pipe none of which was initially installed by 3G Plumbing. I later had performance issues with my water heater. In my telephone conversation with the manufacturer I was informed that 3G Plumbing did not install an air intake pipe for venting outside which was the causing the performance issue. The manufacturer would not honor the equipment warranty until the pipe was installed. I contacted a qualified plumbing company that agreed with the manufacturer and made the necessary equipment correction per the installation instructions. Buyer beware. Do not use 3G Plumbing for water heater installation.
