Far above expectations!
The problem was a gurgling bathtub and water in the sink that would not drain properly. We expected a venting issue - one that might involve going into the attic or onto the roof to investigate the stack or worse, cutting a hole in the ceiling of the room under the bathtub. To our great relief, it turned out that a large wad of hair was pulled out of the sink drain that was impeding the venting of both the tub and sink. Eric took the time to ask lots of questions and thoroughly investigated and both problems are now solved. I will be calling him for all of our future plumbing needs!
