Better service is in our DNA

“The tank and level indicator was delivered today by Dave and I was impressed with his customer service and willingness to ensure it was placed where it needed to be. Although it was a fairly straight forward drop off – on the edge of the road (to be used as a header tank from our dam/pond), he not only dropped it on the sand pad fairly perfecting, he swiftly adjusted it to suit alignment we would like to connect up to. A friendly good morning, swift and accurate drop off and a friendly goodbye.”

“The tank was delivered to my door last evening by your extremely helpful delivery driver. Thankyou all at Devan for the incredibly obliging service. You all made getting a water tank unbelievably easy. I would not hesitate to recommend you all to anyone who wants a tank and if the tank performs as well as you all have I will indeed be a very satisfied customer.”
