I"m getting increasingly worried about the dangers of using PVC pipes, particularly during mashing and lautering as the temperatures are higher. I use food grade flexible pipe, but I don't know if it is suitable for mashing temperature use.It definitely looks less flexible right after use, althpough it gets normal after some time. Does any of you have information about this? Should I use different sorts of pipes? if so, what are the alternatives?

I made my mash tun maniford out of CPVC which is rated for the higer temps. You can find it at any hardware store next to the regular PVC. It's got a yellow tint to it. It's only slightly more expensive, and it works great.

I think we're loosing something in the translation. Pipe generally refers to a rigid material like copper or the CPVC that Jared refers to. He's referring to using it inside the mash tun as the manifold. Tubing is generally the term used for flexable materials. Although PVC or CPVC pipe is somewhat flexable you cannot coil it like you can tubing. Are you using the clear high pressure tubing with the criss cross fiber reinforcement inside of it? And are you using it inside or outside of the mash tun? I use that type for my sparge water at 180*F with no problems. Don't think I'd use it at boiling temps though. There are higher temp. rated tubing materials like norpreme (sp?) and silicone that would work better for that.
