Devan 25,000L Plastic Water Tank

North & South Model: 3500mm (d) x 3000mm (h), 375kg

20 Year Full Warranty & FREE Shipping

Devan Tanks offers a no-nonsense 20-year product warranty on all domestic use water tanks. This is NOT a pro-rata warranty, if the tank is affected by a manufacturing fault the tank will be either repaired or replaced with a brand new tank.

Devan tanks are the only tank that comes with brass moulded outlets. Having metal outlets allows for easy plumbing that is solid and eliminates any risk of cross-threading. Better yet, the big tanks come with two of them as standard!

The unique Devan space frame provides for maximum strength in the dome of your tank which means it won’t 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.

Great service

Good comms and friendly driver

Luke Lee
Outstanding Services

Price was super competitive, communications from purchase right up to the deliver date and time were great and lastly but by no ways the least, the driver that delivered them was so helpful and accommodating in getting them where we needed ( within reason of course). Couldn't have asked for better 100% bang on!

Nigel Fraser
Very efficient service

I knew already of the quality water tanks from Devan but the service from Rural Water was a first for me and was exemplary. I would have no hesitation in recommending them.

Peter Rowbotham
great Service

Like some others, I was little bit nervous paying up front online for a 25000 litre tank, then waiting. But it was all easy, quick to attend to any queries, good product, good cheap price, and delivered just as they said. Very happy with Rural Water
