PEX Expansion Issues

[Integrity Repipe]

PEX A expansion systems can be tricky, especially when transitioning from a crimp system. While PEX A offers flexibility and full-flow fittings, it can be sensitive to fitting tools and technique. Leaks often occur if the expansion tool isn't calibrated properly or pressure isn’t consistent. In my experience, the quality of fittings can vary, and they require proper seating and more time to set up than expected. If you're facing consistent issues, it may be worth checking tool calibration and trying fittings from different brands, as even large suppliers have reported similar problems.
