Hello FN readers: I'm planning a story on on plumbing upgrades at an educational facility. With their heavy levels of usage, one goal is always to try and minimize water use and help ensure hygiene at the same time. In some cases retrofitting to incorporate new-generation, high-efficiency products, including flush valves, toilets and faucets, is the best way to go. The article will profile one department in an education facility that planned and carried out an upgrade of its plumbing system while balancing a host of issues that include specification, cost, energy efficiency and sustainability. If you have a story you would like to share, or know of someone who might, email at email@example.com. Thanks in advance for the help.
