OK, I have decided to take the plunge and jump into all-grain brewing. I have 2 old coolers that I have decided to convert to a Mash/Lauter Tun and HLT. I plan to fly sparge. My question is this: Is there any benefit of building a CPVC manifold for the drain on the Mash Tun, or should I go with the much easier SS braid? If it makes any difference, I have a rectangular cooler, not a round one.
