Why this test cap stands out

Designed specifically for 1-1/2" PVC DWV testing, this Charlotte Pipe cap delivers a reliable seal under short-term test pressures. The Schedule 40 PVC construction resists deformation during leak investigations, while the white finish keeps the connection visible for quick inspection. Lead-free construction adds safety for projects that involve potable water lines or code-compliant installations.

Ideal use cases

• New construction rough-ins where a temporary seal is needed during pressure or water testing of drainage systems.
• Repairs or reconfigurations of 1-1/2" PVC DWV runs where lines must be sealed off during work.
• Educational or training scenarios that demonstrate proper testing techniques for PVC piping.

Practical tips for best results

Before testing, ensure the pipe end and the cap’s mating surface are clean and dry for a snug seal. Fit the cap firmly onto the 1-1/2" spigot end and proceed with your prescribed leak test per local codes. After testing, withdraw the cap as needed and complete any permanent fittings required for the finished DWV system.
