PEX-A vs Copper for Whole House Repipes in Coto de Caza

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 Coto de Caza homes during the estimate. Gated North/South Coto and Golf Estates; larger upscale homes, Santa Margarita water, HOA notice common.
