Under Deck Tanks

Under deck tanks work in much the same way as a standard domestic tank. However, because these installations usually restrict access to the top of the tank they come as a sealed unit without an inlet strainer. For this reason, we strongly advise that you install a standard low maintenance leaf filter at an accessible position in your downpipe to prevent debris from entering your tank. As always, clean water into your tank means you'll get clean water out.

To achieve a water tight seal, the inlet to your tank is a threaded 90mm connection. The overflow works the same way as a standard overflow - surplus water is piped to your stormwater connection. We recommend you fit a mozzie strainer at an accessible point along the overflow pipe for easy removal and cleaning. The outlet of the tank can be connected to your pump or additional tanks using hose with 25mm threaded connectors.

Multiple under deck tanks can be linked together in the one complete installation provided the overflow points are at the same level. Please see our handy guide how to connect multiple tanks for setup tips.

1000 Litre Under Deck Tank

This tank is built specifically for restricted height applications, and will easily fit most under deck and under house spaces. You can see more details on the 1000 litre underdeck flyer. Please allow space above the tank for the inlet pipe connection. You can request that the inlet is installed on one side of the vessel however this will reduce the effective capacity.

2000 Litre Under Deck Tank

A larger under deck tank, with dimensions that will still suit the majority of under deck and under house spaces. You can see more details on the 2000 litre underdeck flyer. Please allow space above the tank for the inlet pipe connection. You can request that the inlet is installed on one side of the vessel however this will reduce the effective capacity.

3000 Litre Under Deck Tank

The largest under deck tank. Please allow space above the tank for the inlet pipe connection.
