stale smell from sink drain
We have a very stale smell emanating from our island sink/sink drain. It is not a sulfur smell, nor is it the water itself. I have tried rinsing with bleach, but to no avail. We are very clean. It is a fireclay sink, if that helps. No garburator. City water, no septic system.
It is a new kitchen (2 mos) and we never had this problem in our old kitchen.
Any suggestions would be greatly appreciated.
