1-1/2 inch Copper DWV Test Cap

1-1/2 inch Copper DWV Test Cap – Engineered for System Integrity and Code Compliance

The 1-1/2 inch Copper DWV Test Cap is a critical component in drainage, waste, and vent systems where temporary sealing is required for pressure testing or system inspection. Fabricated from copper, it delivers compatibility with standard DWV tubing while maintaining structural stability under test conditions.

This cap is used in conjunction with soldered copper DWV lines and provides a reliable barrier to facilitate pressure or leak testing during rough-in stages. Its dimensional consistency and material compliance support streamlined installations that meet both local and national code requirements.

Performance Advantages for Professional Installations
