"The experience beginning with Scott coming out to test the water to Jim installing the water softener tank and reverse osmosis unit was great. They are very professional and informative and the price was just right. I will highly recommend and will refer this company to any family or friends looking to improve their water."

"I just won a beautiful water heater from Legendary Service, and they were amazing. The installation was quick, easy, and clean. The owners came down personally to make sure everything went smoothly. Very nice people and I would definitely go to them for all my plumbing and heating needs!"

"Our water stopped completely. These guys were on the scene right away, and quickly and professionally diagnose the issue. They replaced the pump and we had water again in a few hours. The family has been in the well business for generations. This is a call you never want to make, but if you need to make it I would call these guys."

"We are new homeowners and had a hole in our septic tank made of concrete block, which was sending wastewater into the foundation/basement of the home. It was my first time using Angie's List, and I would recommend Illinois Sewer and Drain to anyone. Joe and his team of experts solved our issue immediately at an affordable price. They even went above and beyond to install a sump pump in our basement to help with the rain water. Quality work!!"

"Danny D, Jerry, and Adam, y’all are stuck with me as a client lol. They provided excellent service, funny, kind, accommodating and explained all that they were doing and all of our goals in maintaining my plumbing.

They showed up last year and this year and just taught me so much in maintaining my home system and their expertise!!!"
