💡 why do pressed copper fittings fail during hydrostatic testing?

Most failures happen because installers skip proper seating checks or reuse worn die sets. Fix those issues quickly with these straightforward steps:
- Slide each tube completely through the fitting until it hits the stop ring
- Wipe away rust and dirt from pipe edges before sliding onto the joint
- Run your mechanical crimper straight across the hex shape for even compression
- Verify press tools match the exact diameter requirements for reliable joints
