Was pricing up a job and spotted this… 50m of 20mm hot water tolerant Pex pipe for $19 is insanely cheap, I suspect this is a pricing error, as it should be easily over $100. EG: https://plumbingsales.com.au/pex-pipe-and-fittings-pull-on/2…
50M of the same brand of non-hot water tolerant Pex pipe in black is $126: https://www.bunnings.com.au/smartex-20mm-x-50m-pex-pipe_p495…
Pex is commonly used for plumbing caravans and motorhomes, water tanks on your property etc. Some people plumb their whole house with it instead of copper piping.
This is not entirely new. I bought a roll of the red 16mm a couple of years back. It was way cheaper than the black, and Bunnings staff could not explain why.
So I used it for both hot and cold.
The red pex pipe no longer seems to be sold in WA (not on website), so I guess it is a clearance?
