Tester- Manhole- Vacuum 36" Head

The Cherne® Air-Loc® Manhole Vacuum Tester with 36" Head (part #210368) vacuum-tests new, existing, and rehabilitated manholes per ASTM C1244. The 36-inch head seals the manhole opening so a vacuum can be drawn on the structure; the gauge is then monitored for vacuum loss to confirm the manhole is sound before backfill or acceptance.

Key Features

• ASTM C1244 testing — the accepted negative-air-pressure (vacuum) method for testing concrete sewer manholes
• 36" head — sized to seal 36-inch manhole openings
• Remote monitoring — the inflation and monitoring system keeps crews at the surface, out of the manhole danger zone
• Fast, accurate results — identifies infiltration and exfiltration problems far faster than water exfiltration testing
• Tests new and rehabilitated structures — suitable for acceptance testing and post-rehab verification alike

Applications

Municipalities and utility contractors use it for manhole acceptance testing prior to backfill and for verifying rehabilitated manholes, per ASTM C1244.
