In this episode of The Build Show, Eric Aune explains what happens when PEX plumbing gets kinked and whether it can be repaired or must be replaced. Focusing on PEX-A tubing, Eric demonstrates a manufacturer-approved repair method using a heat gun that restores the pipe’s full inside diameter—without cutting the line or adding fittings.

The episode breaks down the differences between PEX-A, PEX-B, and PEX-C, explains how cross-linking affects performance, and shows why PEX-A’s shape memory makes heat repair possible. Eric also covers expansion tools, proper installation techniques, and when a fitting is still the best solution.

Ideal for builders, plumbers, and serious DIYers, this episode delivers practical, code-compliant guidance for maintaining flow, pressure, and long-term plumbing performance.
