Grey PVC DWV

[Chad Fabry]

I've never seen it before. It says "DWV" on most of the pieces.

There were like 4 or 5 different shades of grey ranging from electrical grey to almost white.

We ship the grey stuff to upstate to confuse the locals.

It's from spillage at the extrusion plant. Pellets the size of grains of kosher salt come in bags the size of refrigerators. They get dumped into giant hoppers, dropped into screws and forced through dies into what ever part is being made that day. Lots of pellets get spilled. They can either be scrapped or made into odd colored parts.

Everyone should visit a vinyl extrusion plant at least once. There is a fog of fine vinyl particles in the air, the stench of melting plastics, the screech of the cut off saws, and watching the parts extrude is as much fun as watching paint dry.

I visited a PEX plant with a few of the TIJ brethern and actually found it quite exciting. Been so long ago, I can't 'member who all was there!

Thanks Tom. I've seen it many times but never been able to explain it to inquiring clients until now.

I figured something like that. Thanks.

I have a picture of us all somewhere - if I get a chance I post it. That was a great trip - I want to do it again.

The problem is that the grey pvc is to indicate to excavators that the pipe they encounter below grade contains electrical components, white pvc indicates plumbing.

Les isn't sure, remembers something about melting plastic, Mark recalls taking pictures, those other guys are pretty silent. My guess is a few brain cells were destroyed at the plastic plant that day. []
