What to look for
Frequently asked questions
What is the difference between PVC and CPVC fittings?
PVC is for cold water and drainage, while CPVC can handle hot water up to 200°F. CPVC is more expensive but necessary for hot water lines.
Can I mix brass and PVC fittings?
Yes, with a transition fitting. Use a dielectric union to prevent corrosion from galvanic reactions.
How do I choose the right pipe fitting size?
Measure the outer diameter of your pipe for copper or PEX. For threaded fittings, measure the inner diameter. Always double-check with a sizing chart.
Are push-to-connect fittings reliable?
Yes, when installed correctly. They are approved by plumbing codes and can last for decades. Ensure the pipe is cut square and fully inserted.
What tools do I need for PEX fittings?
You need a PEX crimping tool and cinch clamps or crimp rings. Some systems use expansion tools. Push-to-connect requires no special tools.
Why do my threaded fittings leak?
Leaks often occur due to insufficient thread sealant or overtightening. Apply pipe tape or joint compound and tighten to the recommended torque.
Can I use PVC fittings for hot water?
No, PVC is not rated for hot water. Use CPVC or metal fittings for hot water lines.
How do I remove a stuck fitting?
Apply heat with a hairdryer to soften the material. For metal fittings, use penetrating oil. For PVC, cut it out carefully.
Are brass fittings safe for drinking water?
Yes, if they are lead-free. Look for fittings labeled ‘lead-free’ or meeting NSF 61 standards.
What is the best fitting for underground use?
For underground, use PVC or brass. Copper can corrode in certain soils. Wrap metal fittings with protective tape.
