Our handmade copper fountains will patina over time if they are not sealed and treated to prevent it. We recommend a clear coat of Rustoleum or similar every season to keep the original copper color. The quality and longevity stay the same whether or not the piece is allowed to patina. Our metal fountains may be left outside and uncovered in the winter, as long as the pump is removed or protected from water. Installation It is recommended to have a landscape professional install all in-ground basin fountains. All installation kits include a molded plastic basin designed to be lightweight and support large and heavy fountains. Additional support columns will be provided as necessary.
