We bought a Sylvan pool almost 30 years ago, and we've been using their products ever since. We also had Anthony & Sylvan remodel our pool three years ago. Their reps are good and very knowledgeable people, and they help me a lot. They know me and I know them, and we have a very good rapport. We even joke around. I take my water sample to them, they check my pool, and they tell me what I need. I also ask them questions about certain things and products.
