These testers are made with Natural rubber.

An efficient way to test manholes!

These manhole vacuum 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. Can be used in manholes as deep as 40' if desired.
