25 year repair or replacement guarantee:
Purchase with confidence knowing your Rainhaven water tank is not only built to last, but is backed to last.
Made from the highest quality material.
Our water tanks are made from ultra UV (UV20) Food Grade Polyethylene, which means water from our tanks is good enough to drink. They also resist algae growth, provide the highest level of UV stability and the highest levels of colour fastness. IMPORTANT NOTE: Rainhaven is one of the few manufacturers that use UV20 poly in their tanks. Other manufacturers can use as little as UV8 in their tanks, which makes them far cheaper to produce and often as soon as you fill them with water, they'll start to buckle and warp out of shape.
Corrosion free
Our tanks won't corrode, rot or rust away.
Quality control:
During the manufacturing process, Rainhaven water tanks go through a quality control procedure involving an ultra sound test, impact test and a water fill test.
Advanced design:
Over 3 years of research and development has gone into Rainhaven water tanks.
Available in a range of sizes:
There is a Rainhaven water tank size to meet the water usage needs of your home.
Ultraviolet light stability:
Rainhaven water tanks are manufactured from the highest grade of UV stable Poly available (UV20), which means they last longer in the harsh Australian climate.
Built to last:
Manufacturing the water tank in one piece ensures a strong design that won't buckle, twist, warp or leak.
Minimum wall thickness of 4.5mm:
Rainhaven water tanks have a minimum wall thickness of 4.5mm, which not only ensures strength, but it also aids in preventing algae growth by inhibiting the transmission of light.
Available in a range of colours:
To suit the decor of any home. Unlike corrugated metal water tanks, the colour is not a powder coating that can be accidentally scratched off or dented when you're installing the water tank in locations where there isn't much room.
Simple to install:
Rainhaven water tanks can easily be installed. A licenced plumber can also connect the tank to your toilets, washing machines etc.
Environmentally friendly:
Utilise water that would otherwise end up as storm water that can pollute our waterways. Polyethylene is also a recyclable material. Tanks come with 3 x one inch brass thread outlet for tap or pump.
