Though the pex-al-pex is harder to work with, than plastic-only pex, it works much better for radiant heating. I'm very pleased with the Vevor product, and I hope it lasts for many years to come!
I bought it for a future radiant heat system in a concrete slab. I had the system pressurized during the pour and it held up. We were careful but it seems to be durable enough. Great for the price.
