摘要： A cushion maintaining device for use with a water service line is operative to automatically maintain a gas cushion in a chamber within a body member mounted on and extending upwardly from the water service line and positioned adjacent a valve, faucet, or the like to absorb shock caused by sudden closing of the valve or faucet. The cushion maintaining device includes a positive electrode and a negative electrode positioned in spaced apart relation within the body member mounted on the water service line and electrically connected to a source of electrical current. Electrical components are connected in the circuit to the electrodes to convert current thereto to pulsating direct current to thereby convert water in contact with the electrodes to gas which maintains a gas cushion within the body member.
