Walkover-style DoubleWall Monitored Transition Sump

Due to its integrated water drainage channel under the cover it is ideal for areas with frequent rain or applications where water may occasionally flow over it. The walls have a compressive strength of over 1300 PSI and ship under a continuous vacuum test at 20”Hg or greater with a combination pressure/vacuum gauge factory-installed. Each sump also includes monitoring fluid. It is similar to the B-500-D-AB model except for its unique interior water drainage channel (which drains accumulated water below the concrete pad into the backfill) and flush-mounted diamond-plate cover. This transition sump features a rear panel raised above grade with your choice of AST compression fittings factory-installed, c-channel on the interior for hanging hardware, concrete anchoring flanges and integrated structural sleeves for our optional riser rack system.
