You all did such a wonderful job with recommendations for break repair that now I've decided to come to you all with a plumbing issue. I recently had my bathroom remodeled and wanted to re-use the showerhead (it's awesome and not a low flow). Unfortunately, during the demolition, a critical part was not kept track of, and now they cannot mount the showerhead. Some sort of plastic seal is missing. Any plumbers out there that might be able to help me find this hard to find part?
