"It was a pleasure being able to have Robert come out to help with my family s water heater issues. He was very friendly and is a well experienced plumber (I believe he told me 20 years as a licensed plumber). Response time was excellent, same day service, and the cost of service was more reasonable than any other estimates we received. I would highly recommend Robert and Drain Right to my friends or family, and I will be reaching out for his plumbing services again if I ever encounter any plumbing issues while I m still living in the Bay Area."
