PEX Leaks in Newer Homes?

PEX piping in newer Kingwood homes has shown unexpected leaks caused by oxidation from city water — specifically chlorine and chloramine used for disinfection. These chemicals can weaken expansion-style PEX from the inside, leading to hairline cracks near bends and fittings. Homeowners have two main options for prevention: installing a whole-home carbon/KDF filter to reduce oxidizing agents at the source, and adding an automatic shut-off valve for peace of mind against future leaks. Brazos Home Services now installs PEX-B with stainless steel crimp fittings to help minimize risks.
