Why Choose An Aquamate Water Tank?

Food Grade Tank Liner

Aquamate use a food grade tank liner suitable for potable water use, which is certified to NSF testing standards. The liner is a “monofilament” construction, as opposed to a coated mesh, because it’s resistant to fatigue cracking and super stretchy – both important characteristics for a durable water tank.


20 Year “No-Leaks” Warranty

Aquamate’s 20 year “No-Leaks” warranty leads the industry and is supported by over 30 years of experience choosing the correct materials to survive the toughest conditions.



Installed by Trained Technicians

All tanks are installed by Aquamate trained and certified technicians, meaning you can be sure that your tank will stand the test of time.
