Had an issue with my sump pump discharge flowing back into the basin. I had another plumbing company quote me almost $4,000 to replace the entire basin, the pump, and all related drain lines. I got a second quote from O’Hare Plumbing. Within 15 minutes he told me the problem was that the line going out from my basin was clogged, and that was causing the issue. It was fixed the very next day at less than 10% of the cost of that previous quote. The guys at O’Hare Plumbing were honest, informative and very nice to work with. Highly recommend.
