These smoke blowers are installed on a manhole to blow thick smoke into the underground pipe system. The smoke identifies points of inflow where surface water is entering the pipe system.

These pipe joint testers verify the integrity of joints in large diameter, precast concrete pipe systems based on the standard practices defined in ASTM C1103. This equipment uses water or air to test the system and inflatable blocking plugs to stop flow in the pipe while testing.

These items replace worn parts or replenish consumable components in pipe testing equipment.
