I have two houses that have different drain plug / nut design in the basement.
House 1 has the plug all the way inside drywall like this:
Do I suppose to drywall over and hide it?
Or do I install an access panel there?
House 2 has the plug showing out like this:
When I put my hand there, it's blowing cold air from the outside. So I need to seal or cover it.
- What is the best way to cover this when the nut is extruding out the drywall?
