Tank Sumps

Water Resistant

APT™ brand water-resistant tank sumps feature a water-resistant, 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.

Water-Resistant Sump Lid

The water-resistant design of the gasketed sump lid is critical to keeping liquids out of the sump.

  • Four integrated hold-down lid toggles provide compression between the lid gasket and the riser, preventing liquid from entering into the sump.
  • The lid toggle pegs are molded into the riser and do not penetrate the lid or riser, eliminating these areas as potential leak points.

Ensure 90° Pipework Entry

16 flat surfaces around the sump base provide an ideal entry surface for pipework.

  • These 16 flat surfaces help to facilitate proper 90° sump entry for pipework from multiple angles.
  • A proper 90° entry into the chamber is necessary to avoid creating stress on the pipe entry which can weaken the system over time.

Field Height Adjustable

The height of the sump riser can be cut down in the field to meet the varying needs of different installation applications.

  • Accommodates unforeseen on-site grade level changes to ensure installation is kept on schedule.
  • Minimizes the need to stock multiple chamber height options.
