Another reason the cable guys are putting heavy plastic covers 2 ft up on cable runs down the poles into the ground.My favorite pipe fix...

We were playing hot potato with the plastic potato with a timer. 

I have put on the plastic ant traps but these don't seem to be working.

You also might offer them $200 to do the repairs while they’re still in the space, maybe move any furniture out of that area too and cover other stuff in plastic.

Just noticed u are fixing the issue, also to add add plastic vapor barrier between studs and wall

@Christopher Cills Depending on your property, the preformed plastic laminate tops at box stores are a good value.

What are these Plastic panels called that go over the lights ?

So, from my limited scope of experience here are my take-aways:Vinyl IS 100% waterproof because it is 100% plastic (actually, it's probably not technically 100% plastic, but in essence that is what it is). 

Hi,My friend is building a ~600 sq ft ADU in So Cal/Los Angeles and is wondering what type of pipe might be best from a quality/maintenance/cost standpoint within the interior of the ADU (I realize that the line connecting the ADU to the sewer line might be HDPE or some other plastic pipe...)? 

For uppers, shimming can still be required, such as behind the steel support rail if the wall is horizontally wavy, or at the bottom of the cabinet if the plastic spacer they include isn't thick enough.
