“Do you need a vintage plumbing part and nobody seems to be able to find it in your area? Save yourself time and hassle and go to Noel's Plumbing website. You can text them a photo of the part and they will find it in minutes and give you the link to order it, all at a competitive price. My plumbers seem incapable of doing this and hand the job off to me. What can you do? But Noel's always has the 1930s parts I need or the aftermarket part that will get the job done. If I need it fast I can get it in 2-3 days from them and they know exactly what they are doing. It's a good old-fashioned plumbing store with all the parts you could possibly need and people who know how to get them. The service is top level. The staff pick up the phone after one or two rings. They are polite and KNOWLEDGABLE. I'm so tired of dealing with folks who can't find a chicken in a hen house. LOL. ”
