A structure and method for ensuring the continuing operability of a fire protection sprinkler system that includes the addition to the water in the piping of a chemical compound that adjusts the Ph level to a value between 9.5 and 11 to prevent electro-chemical corrosion and formation of sludge by surface reducing bacteria, and the use of a non-conductive fitting between each sprinkler head and the piping to prevent galvanic corrosion due to contact between dissimilar metals.
