Pride Plumbing was called out to investigate the cause of a water stain on a downstairs ceiling. We cut an access in the ceiling and found that the leak was being caused by a loose upstairs bathtub/shower drain. We removed the shower drain, applied plumbers' putty to its threads, reinstalled it, and tightened it. We tested for leaks with no further issues. We also found a bathroom sink that was slow to drain. We removed and replaced the sink's popup assembly and tested for leaks and proper drainage with no further issues.
