We have recently purchased a 2300 litre water tank from Alliance Mouldings for both drinking and garden consumption. Without reservation we can commend not only the product but also the prefessionalism, efficiency & expertise provided and totally and wholeheartedly recommends that 'Every home should have one'. Don't just think about it - do it, you won't regret it!

12 months ago we purchased a 2300 Litre water tank with pump from Alliance Moulding to help save a bit on the rising cost of water these days. We were so impressed with not just the product bult also the prefessionalism shon from the time they came out to give us a quote, arrange delivery and complete the installation all within 7 working days, we have just 3 more Under Eave tanks installed. I have no hesitations in recommending Alliance Moulding to anyone. Thanks again Ian and your staff for all your assistance you have given us.
