Vitaliy came to my house a few weeks ago to help me drain my hot water heater. We found a lot of calcium deposits as expected. A homeowner should drain their heater every 6 months to a year depending on usage. While he was at the house he also came upstairs to check our master bath room shower drain. His snake was more effective than Draino.
Next he walked 10 feet to my wife's drain on her side of the bathroom. Having a woman with long hair before us and my wife also having long hair, lets just say he was able to open the drain. Happy to have a good plumber local to me!
