“I contacted Just Tanks to look at providing 2,000 litres of rain water harvesting storage. We decided to install the tanks due to concerns that we would have another water shortage in Auckland. The tanks and the plumber arrived and it was installed as promised. We are happy with the outcome and the workmanship.”
