Yes, Home Depot is a big "box" store, but when you're looking for a great selection and free advice from people who know how, this is the place. After several trips to local, smaller stores, we couldn't find everything we needed for a water filtration system, pipes to replace under the kitchen sink and some tub enclosure issues. Every time we go to the plumbing section, we find detailed, helpful advice to guide us on our project, start to finish. Just make sure you find someone who actually works in the plumbing section, not just an employee. Mark has always been super helpful and always reassures us that yes, we can solve a lot of these issues ourselves. He always encourages us to come back with questions and to let him know the outcome.
