Hired John Baethke & Son to handle our new tankless hot water heater install plumbing needs. They came highly recommended by Current Electric in Glenview -- who handled our electric needs for this with much success by the way! We had Cormac handle the work and he was super. Answered all questions, provided me multiple options for the work needed, and completed all needed updates in one single day.
The tankless unit we ordered from Amazon (Eco 18) needed to be replaced due to a hairline crack but all of the work completed by Cormac was working and looks great. I couldn't be happier. These are my new go-to plumbers going forward.
Photo of the final setup is attached. They installed clean supply and feed lines to the tankless along with pressure relief valves for both sides. Clean and sleek!
Be sure to ask for Cormac by name to handle your work -- he rocks!
