A young man from Waterworks came to fix my humidifier. He was nice, but when he was moving the water valve to set it, it started to leak. I noticed this only a few days later, as this happened in my basement. I called the owner who was rude and told me I broke it and there was no way they would come back and fix it. I disputed the Visa amount I paid and Visa asked me to get another plumber to fix this problem. It took this second plumber only 10 minutes to realize that the young man had loosened the water valve while moving it to adjust it, and this is why it was leaking. I am sure that if I had talked with this young man instead of talking with his boss, he would have come or told me over the phone that this may have happened. I also wish I had read the poor reviews in this website before I hired them. The owner had also given me a quote for the part to install, but then when the young man came I was charged $25 more for the part.
