@Glamisduner Don't mind the Tesla bear with the slow car. ^^^^
As for the pipes, run Pex. Lining is just a temporary patch that will give you more grief later.
Can't get a loan cheaply to redo pipes. But you can extend loan terms on the car and pay down principle faster as resources come up.
How does that make me a Tesla bear? Just because I didn't echo your rah rah? Weird
