Added Value You Won’t Find Elsewhere
Unlike other tanks, Devan moulds brass outlets directly into the tank wall for rock-solid durability and no risk of cross-threading. Two outlets are standard on large tanks, giving you flexibility for multiple connections.
Devan’s unique space frame dome design provides unbeatable strength and reliability. Tanks come vented for domestic use as standard, eliminating suction dome failures (the #1 cause of tank issues). Pair with a Devan vented overflow kit (optional) for maximum performance.
Nationwide Delivery
Devan manufacture in Tauranga and Christchurch and run a fleet of custom-built delivery trucks. That means fast, efficient delivery to both the North Island and South Island – even to the main offshore islands (ferry costs may apply).
