Hi - Wondering if anyone has a solution or ideas about our cold water problem. We get a strong bad smell (sewer-y) in both bathrooms. This affects the cold water only. It does not affect the cold water in the kitchen or showers.
Possibly pertinent: we did some remodeling about 3 yrs ago which involved plumbing. In upstairs bathroom, we replaced the toilet, changed the vanity and sink, and re-did the shower. At the same time we changed the sink in the downstairs bathroom.
Thanks in advance for any insights.
