PEX-A vs Copper for Whole House Repipes in Rancho Santa Margarita
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 Rancho Santa Margarita homes during the estimate. Melinda Heights and Robinson Ranch late-80s/90s copper beginning to leak; Santa Margarita water.
