A Guide on Pipe Fittings and Their Use
Ferrule pipe fittings vary by size, purpose, and material. You often must tie together pipes of different materials with transition fittings. The materials in common use today — copper, PVC and CPVC, PEX, ABS, galvanized steel, and cast iron — can mostly all be connected with appropriate fittings.
With all the different pipe sizes and materials out there, things can get confusing. Ferrule pipe fittings
for water lines are different than those for drain and waste lines. It’s no wonder professional plumbers don’t go anywhere without a truck full of fittings. It’s their magic cupboard, letting them complete installations and repairs much more efficiently than amateurs like me.
