To ensure a successful installation and meet warranty requirements please install to our recommendations. Fibreglass water tanks are designed for above ground installation only. Dig a 50mm deep level base and cover with 25mm depth of fine (7mm or less diameter) scoria bedding or similar.
Position tank on base. Fit an outlet valve and half fill tank with water on the day of installation.. Pipe the tank overflow away to storm water dispersal to prevent water overflow undermining the tank base.
