At Brisbane Hot Water Heaters, our quoted prices are all-inclusive for your hot water system, fully installed to meet all council regulations. Unlike some other businesses that quote a price and then add the cost of valves, we include everything in our pricing. All hot water systems require a certain number of valves that do not come with the hot water system, and not including them in the quoted price is just a ploy to dazzle you with a slightly cheaper initial price and then overcharge you for the valves.
