When installing a water meter which fittings should be used?

• A. Compression
• B. Soldered joints
• C. Flare fittings
• D. Push fit

Answer: (A)

Compression fittings are preferred when installing a water meter because they provide a reliable, heat-free seal that can be installed quickly and, if needed, removed without cutting or re-soldering the pipe. The compression nut and ferrule compress around the copper pipe as you tighten, creating a tight, leak-resistant connection suitable for the service line to the meter. This approach is forgiving in the field, supports easy disassembly for meter maintenance or replacement, and is widely accepted by plumbing practices for potable water service connections.

Soldered joints involve heating the pipe to fuse the joint, which isn’t ideal near a meter because it requires flame and careful control near sensitive components, making it harder to service later. Flare fittings demand a flared end on the pipe and more specialized steps, which can complicate the service connection. Push-fit connectors can be convenient but may not be approved for all meter installations and can raise concerns about long-term reliability under pressure and temperature, depending on code and manufacturer guidelines.
