[COLDBASS]

Copper is the way to go.
Mapp gas for beginners, Acetylene for experienced folks.

Dialectric couplings, bushings, unions...forget about it. Couple years later you'll see how worthless they are.

Take your time do it completely and you will have no regrets.

Trick is to clean the pipe well, apply flux and heat properly.
The solder will flow.

Oh yeah, make sure the line is empty of water, otherwise you'll never get the right heat...

Give yourself some time and you'll be a pro. Dont forget to strap and insulate the pipe properly.

A helper is a must especially if you are under the house...
