Devan have manufacturing and distribution centres located in Tauranga and Christchurch which have the benefit of being able to provide excellent customer service to both North Island and South Island customers. With a fleet of eight custom built delivery trucks, Devan deliver nationwide and even onto the main islands surrounding New Zealand (please note, where a ferry is required extra charges may be involved). Added Value Devan Tanks offers a no nonsense 20 year warranty on all our domestic use water tanks. Our tanks are manufactured to the highest standards utilising advanced technology and production procedures.This is NOT a pro rata warranty, if the tank is effected by a manufacturing fault the tank will be either repaired or replaced with a brand new tank. Devan Tanks are the only tank that come with brass moulded in outlets. Having metal outlets allows for easy plumbing that is solid and eliminates any risk of cross threading. Better yet, our big tanks come with two of them as standard! Devan Tanks are manufactured from the highest quality polyethylene which is ideally suited to our moulding technique giving long life and trouble free service. Polyethylene cannot rot or corrode, and is ultra violet stabilised for harsh environmental conditions. The unique Devan space frame provides for maximum strength in the dome of your tank which means it wonít pop in when you are installing or servicing your tank nor will snow loading have an effect. Devan Tanks come vented for domestic use as standard. Suctioned domes are the number one cause of failure with water tanks and this built in feature, combined with the Devan vented overflow kits (optional extra), will eliminate this issue for Devan tank owners.
