  • "well-oiled machine"

    Guys I am in the process of buying a 22,700 water tank. I would like to bring to your attention one of your employees Mr Adam Briggs. I have asked advice about many different issues & this guy has replied promptly, given great advice & has been a pleasure to deal with. I work for National Parks & look after Sydney Harbour, I have staff & know the importance of having good staff. This guy is an asset to your company. The overall make up of your company I can see already is a professional well-oiled machine. Well Done Regards Darren

    I recently purchased a tank online (Inv 6692) that was delivered by Tweed Tanks last week. This is the 4th Duraplas tank I have purchased. I wish to commend the delivery driver on his prompt & professional service. The experience was positive & exceeded any expectation I had. I would also like to commend you on delivering a quality product. The price was not the cheapest but was extrememly competative & I chose to support a local company. Considering the quality of your product, I believe I received the best available product for a good price. I will continue to recommend & use your products. Regards, Alex from Stokers Siding
