Water Tanks in Gympie Region: State and Council Requirements for Residential Homes


Today I received my water tank from National Poly Industries and would just like to say a big THANKS to yourself, Tony the salesman and all your staff for making it so easy from purchase to delivery. Even though I thanked the delivery driver JOHN I just wanted to let you and your team know how polite over the phone and face to face he really was. John couldn't have done anymore if he tried, delivering my water tank.

Jason Lynch, Mudgee NSW

Very happy - the service was very excellent and prompt. When I checked around for a price they got back to me straight away - I was kept waiting by other companies. Placing an order and receiving the acknowledgment and delivery date was also very prompt. They confirmed all the details with me and the driver was excellent and put the tanks exactly where I wanted them to go. Really happy with the tanks. All round excellent experience and will definitely order my next tank from them.

We have had exceptional service from National Poly, They have supplied 70 rainwater tanks to date with a further 110 to go. The ordering process is without drama and after sales service exceptional. We have not had 1 problem with a tank.
