What the AI looks for in Pipe Fittings

Joining method matches the pipe: Each material has its own method: solder or press for copper, crimp, clamp or expansion for PEX, solvent weld for PVC/CPVC/ABS, threads for steel. Push-to-connect works on copper, PEX and CPVC. Using the wrong method is the most common cause of leaks.
PEX fitting standard: Expansion fittings (ASTM F1960) are for PEX-a only. Crimp and clamp fittings (ASTM F1807 / F2159) work across PEX types with the matching ring and tool. Expansion fittings do not seal reliably on PEX-b.
Pressure and temperature rating: Use CPVC or metal, not PVC, for hot water. Check Schedule 40 vs Schedule 80 for pressure lines. PVC softens at hot-water temperatures.
Lead-free brass: Brass fittings for potable water should be marked lead-free. Use dezincification-resistant (DZR) brass where water is aggressive. Ordinary brass can leach lead or lose zinc and fail.
Dielectric isolation: Use a dielectric union or nipple between copper and steel. It prevents galvanic corrosion at the joint.

BSP-thread fittings on NPT plumbing.
Push-to-connect fittings buried in walls without an access panel where code prohibits it.
PVC fittings on hot-water lines.

Only with a cement specifically rated for ABS-to-PVC transitions, and many codes restrict this. A mechanical transition coupling is the safer route.
