[Cob] pipes

[karl and tabitha o'melay]

i second that... pex is great, easy to work with and anyone with limited

heat gun & it'll memory-shape to origional. yes, pex is also for radiant 
heating. PVC is evil--i would never consider it for my water supply.

see http://www.nextwavefilms.com/bluevinyl/sundance.html regarding PVC
