WATER-RESISTANT
TANK SUMPS
APT® brand water-resistant tank sumps feature a waterresistant, gasketed lid with integrated hold-down toggles to
prevent liquid from entering into the tank sump. Four lid
toggles provide compression between the lid gasket and the
riser without the need for any penetrations—eliminating
potential leak paths.
SPECIFICATIONS
HIGHLIGHTS
• Durable, yet lightweight polyethylene construction
with robust 0.3" (7 mm) wall thickness.
• The ribbed riser provides field height adjustablity,
allowing the sump to be cut down in 4.3" (110 mm)
increments on site using standard tools to easily conform
to varying site conditions.
• Available in deep burial [58" (1,471 mm) maximum height,
31.9" (810 mm) minimum height] and medium burial depth
[45" (1,140 mm) maximum height, 31.9" (810 mm)
minimum height] models.
• Water-resistant, gasketed lid with integrated hold-down
toggles prevent liquid from entering into the sump.
• 16 flat pipework entry surfaces surrounding the chamber
base ensure proper 90° pipework entry into the chamber.
