Fittings And Baffle Pre-Installed
Every tank arrives with its fittings and internal baffle already fitted, so a licensed plumber can complete a 10 minute hook-up rather than assembling components on site. The one piece design includes lifting lugs for easier handling, though suitable lifting equipment such as a forklift is required to unload the tank when it's delivered.
Self-Anchoring, Low Profile Design
No concrete is required to anchor this tank, and its low profile design keeps excavation depth to a minimum, simplifying installation on most sites. An optional riser extension (555mm W x 530mm H) is available for sites where additional height is needed. Always check with your local council for exact requirements before installing.
Two Sizes, Backed By A 10 Year Warranty
The 3,100L tank suits a 1 to 5 person household, while the 4,550L tank suits a 6 to 10 person household. Larger households can still use the smaller tank, though may need more frequent pump outs as waste can build up more quickly. Both sizes are Australian manufactured and backed by a 10 year warranty.
