What happens here

Proceed to examine the sink's drain assembly and P-trap for further signs of corrosion. Look for rust on metal portions of the drain pipe connecting to the sink basin and any associated hardware. Significant corrosion in these areas can indicate past or present leaks, or chronic high humidity under the sink.

Goal: Identify corrosion on the sink drain pipe and related hardware.

What they say

Hide

So I came over to fix a leak at my neighbor's house across this tree. You can see that drip right there. But I noticed a lot of other things that were very alarming. You see all this rust right here. And you see this corrosion right here. This is underneath his sink. Right, you get up here and you see it everywhere. It is wild. Take even the screw heads and the hinges, the braided flex supply lines are starting to break down.
