PEX-A vs Copper for Whole House Repipes in Tustin
Material comparison using Uponor ASTM F1960 expansion PEX-A.
PEX-A expansion fittings (Uponor, ASTM F1960) resist corrosion from local water and carry a 25-year warranty. We do not use crimp PEX-B. Copper remains an option when the inspection and owner preference support it. We compare actual routing, fitting count, noise, and longevity for Tustin homes during the estimate. Old Town and Tustin Ranch 1970s–90s; Tustin Water District hardness and common 1970s copper pinholes.
