Depth adjustment for M-43D installations

Made to fit the Passway™ M-43D grease trap, the 150mm tank riser is used to extend the depth of the unit in the ground where deeper pipe connections are required.

This is especially useful where the installation needs to suit sub-slab, foundation or paving conditions and the grease trap must be matched to site-specific plumbing elevations.

Installations needing extra riser height

• M-43D grease trap installations with deeper inlet or outlet pipe elevations.
• Sub-slab installations where the grease trap depth needs to match the building drainage layout.
• Foundation or paving areas where the finished surface level must be considered.
• Projects where service access needs to remain practical after the final surface is completed.

Core product details

Confirm riser need before installation

The riser should be selected before final installation so the unit depth, inlet height, outlet height, surrounding surface and service access all work together.
