I was delighted with my recent experience at Dupont Plumbing. Last week I bought a Toto Entrada toilet (at a reasonable price) that was perfect for my small bathroom. This week I returned to Dupont Plumbing and bought an American Standard Cadet Pro for our second bathroom. Throughout the entire process, Dupont's staff were both patient and knowledgeable. The whole experience was much better than a big box store both in terms of the staff's product knowledge and their suggestions on how to accommodate the unusual configuration of pipes in my bathroom.
