Ceiling Saver is a long term cost saving device that fits over the vacuum breakers of a geyser. Vacuum breakers are known to fail, resulting in flooding of ceilings and damages within a home. By using a Ceiling Saver the water is diverted to the outside of a home via an overflow flow pipe preventing flood damage to the interior of a home. Its recommended to install a ceiling saver over both the inflow and outflow vacuum breakers on your geyser.
