Homeowners rarely concern themselves with plumbing until they discover a leak, run out of hot water, or begin to remodel their house. However, plumbing is one of the key areas in a home where one can reduce monthly utility bills and negative impact to the environment with wise choices and quality installation of systems.
PATH maintains several plumbing technology development projects. Many of the technologies listed in the
PATH Technology Inventory can help reduce water waste, as well as water and energy bills. The
ToolBase information portal also has descriptions of the latest plumbing systems and their advantages.
