A friend of mine tried to fix a constant hissing sound coming from my toilet tank, and unfortunately when he tried to move an old, fragile plastic piece it snapped off in his hands. I was sure I would have to replace the entire toilet (it's about 15 years old). I decided to try a plumber instead and found F1 Plumbing on Yelp. After reading all the positive reviews I called them and Daniel came over to have a look. Instead of recommending that I replace the toilet Daniel was able to just replace some of the older parts in the existing tank. It worked fine for a few days until ironically another old piece in the tank came loose, resulting in a new constant hissing sound. Now I was sure I would have to replace the toilet! I called Daniel and he came back the next day to fix this other part. He didn't even charge me for the second visit. Now my toilet is quiet once again and it works beautifully. Daniel was very professional and courteous during his visits, and he worked quickly and left no mess behind. I was glad I called him instead of just replacing the toilet since it save me a ton of money
