An efficient way to test manholes!

These manhole testers provide the most efficient, accurate, and cost-effective method of testing new, existing, and rehabilitated manholes, per ASTM C 1244.

Vacuum testing identifies infiltration and exfiltration problems by creating a vacuum in a manhole and then monitoring a gauge for vacuum loss. Less expensive and faster than water testing, the manhole testers' remote-inflation and monitoring system keeps users away from the danger zone.

Bladder-Style Head Assemblies

Features:

• Seals the inside diameter of the manhole at frame or cone
• Supported by a durable aluminum brace
• Push-pin rod design for easy depth adjustment
