About eco sac

What is eco sac?

eco sac® is the superior rainwater storage bladder tank system that hides away under floors and decks. It does not need to sit on a concrete slab or pavers but the ground does need to be relatively level and have a height clearance of at least 700mm. If you have less than 700mm available, call us to find out how low you can go!

eco sac® is so durable that it comes with a full 10 year warranty.

eco sac® is sold through all plumbing merchants and can be installed by any licensed plumber. Alternativley, you can phone us on 1300 72 66 70 for information on how to get an obligation free site inspection and quote from a trained professional.

eco sac® is the best rainwater storage bladder tank solution for you because:

It is the only bladder tank with absolutely no moving parts and easy to access side-fill pipework
The bladder tank seams are overlap welded for maximum strength (be wary of "fuse" welds)
It comes with a heavy gauge galvanised or stainless steel frame which stops the bladder tank rolling against your piers (a risk with frameless brands)
It is the only bladder tank made from PVC accredited to AS4020, Australian standard for potable water
It has a full 10 year warranty on material and workmanship
Every sac is tested to US Defence Standards prior to leaving our factory. It is photographed and its unique serial number recorded and tracked to its final location in our system.
Eco Sac can provide a tailor-made cover to give your eco sac® extra protection and keep it looking new for longer
There are 66 different sizes available - giving you a greater range than any other bladder tank. All bladder tanks fill to a maximum height of 600mm. For available size range, dimensions and capacity – click here.
Every sac comes with a standard 100mm inlet and 2 x 32mm outlets. Secondary sacs can be joined together with a 100mm manifold giving unlimited storage capacity and a superior filling mechanism for secondary sacs (see diagram below)
It is 100% Australian owned and made
