Passway™ Installation Overview

Intercept grease close to the kitchen

Position the grease trap as close as reasonably practical to the kitchen wastewater source while keeping the cover and internal components accessible for routine servicing.

Outdoor or below-ground installations should be arranged so stormwater and surface water cannot enter the grease trap.

Consider how grease, solids and sludge will be handled during servicing. The site should provide enough safe working area for waste containers, service equipment or a dedicated on-site grease-composting system where one forms part of the approved site-management arrangement.

Keep the body level and correctly supported

The unit should be supported on a stable, level base so the body, cover, seals and connected drainage remain correctly aligned.

Excavation dimensions must be based on the actual dimensions of the selected product and allow suitable space for bedding, pipe connections and installation access.

Surrounding paving, concrete or structural work should not transfer unintended loading into the grease-trap body or access cover.

Confirm the selected inlet and outlet arrangement

Passway™ connection sizes and adaptor arrangements vary by product. Confirm the selected product configuration before pipework is completed.

Drainage should be correctly supported and installed with the required grade so grease-laden wastewater is not left standing in upstream pipework.

Protect the service opening

The product cover and surrounding installation must suit the actual pedestrian or traffic loading at the site.

Where vehicle loading may occur, a separately supported and appropriately load-rated access arrangement may be required rather than allowing vehicle loads to transfer directly into the grease trap.

Fill and test before normal kitchen use

Confirm all internal components are correctly installed and fill the grease trap with clean water until the normal operating level is established and water flows through the outlet.

Run clean water through the connected fixtures and inspect the inlet, outlet, body, cover seals and any riser or extension connections for correct operation and leakage.
