I will be replumbing an 80 year old house with PEX that currently has galvinized pipe. I am interested in opinions as to what type of connector system is best (i.e. most reliable as well as easiest to install) cold expansion, crimp, clamp, quick-connect. This may also be closely related to the manufacturer of the tubing so I wouldn't mind hearing opinions on the best/worst mfgs. Thank you in advance for your response.
