I want to use pex-A tubing for installing my hot water heater because I've read it's more flexible than pex-B. I have some questions about pex-A tubing:
1) The big box stores sell pex-A brass connections, and I've removed one from a package and it fits tight inside the tube, however, I watched a youtube video showing using a tool inserted in the end and expanding it, slipping a small white fitting over the outside and then inserting the brass fitting. Why would that be required when appears all that would need to be done is to insert a brass fitting in the end of the tube and put a crimp ring over it and then tighten it?
2) Another alternative to fittings are the compression fittings. Are they as good as using crimp fittings?
3) I've read about some lawsuits about using red/blue colored pex tubing. Would it be better to use white tubing and wrap a red piece of tape around the hot tubing?
