As the preferred water bladder solution for architects, designers, and hydraulic engineers, the Eco Sac Bladder Tank from Waterplex knows how to live up to its reputation as the ideal water storage solution for your property. This tank is able to hold more water per square metre than nearly any other type of bladder tank. It takes all of that space and uses it to its fullest advantage. Designed with a steel frame that makes sure that tank nor its pipes are moving, this tank stays in place when expanding or deflating with its pipes and fittings locked in place by a steel mounting plate, which also takes the stress off of the pipes. Available in 66 different sizes, the Eco Sac is able to hold between 1,700 litres to 10,700 litres of liquids and can fill to a max height of 600mm.
