canopy Posted August 31, 2016 Share Posted August 31, 2016 It seems like before there was only yellow pvc used for electrical. But now white pvc is becoming widely available next to yellow also apparently for electrical usage. I have asked the sales people at various places about the differences only to hear inconsistent answers like "only difference is the color" or "yellow is imperial, white is metric". Does anyone know what the actual differences are and when to prefer one over the other? Link to comment Share on other sites More sharing options...
Crossy Posted August 31, 2016 Share Posted August 31, 2016 I use the white when it's on the surface, easier to paint. Other than colour I don't think there's any real difference. I've also seen white water pipe and fittings. Link to comment Share on other sites More sharing options...
Ginkas Posted August 31, 2016 Share Posted August 31, 2016 (edited) A little searching on a couple of sites suggests - Household water supply - Artic Blue Electrical wiring & Telephone Cable - Light Yellow Drain, Waste or Vent - White (PVC) Black (ABS) Agricultural - Grey Chemical Products - Dark Grey but the above doesn't seem to be absolute except in a few countries' codes Edited August 31, 2016 by Ginkas Link to comment Share on other sites More sharing options...
