Waterline tanks were very easy to work with from start to finish. They pointed out and quickly reimbursed an overpayment I had made. They kept to their timelines, which is impressive these days. Their delivery man was polite and friendly - nothing was a problem. Thank you!

It was a real pleasure dealing with Katie, Joe and the installation team. They were professional to deal with and quickly answered all my questions. Installation of the colour bond tank lid onto my old concrete tank was very fast, efficient and it looks awesome. Thanks Team.
