Water-Flo has done an excellent job removing my water smell: I have had water odor (rotten egg smell) from the well water. Joe and his colleague at Water-Flo did an in-house water test and prescribed an iron filter tank. After paying the deposit, Joe and his colleague installed the filter tank (which only took 2 hours) during another appointment. The smell is instantly gone. The entire process is smooth, and they are on time for appointments, respectful, and experienced. Most importantly, the price is very reasonable and transparent. I would highly recommend them.
