smell from under kitchen sink
We have a smell (like mildew) coming from under the kitchen sink, especially when the dishwasher (a 6 year old bosch) is running. The drain has an Oatey sure vent and I am thinking that the smell is coming from there perhaps because it does not seem like it is coming from the garbage disposal (ISE 777)which is also under the sink. Does anyone have any idea how to fix this problem? I am scared to mess with the sure vent, but I wiped the top with a disinfectant wipe and it definitely has some mildew. Can it be cleaned?
Any ideas or fixes are greatly appreciated!!
