Abstract
A vacuum surge suppressor for swimming pool safety valves. These valves normally sense and then instantly relieve excessively high vacuum levels in the pool's drain line. Such high vacuum levels occur when an individual becomes trapped by the suction at the pool's drain port which is connected to the drain line. The valve relieves the high vacuum level in the pool's drain line and the suction at the drain port by bleeding air into the pool's drain line, causing the pump connected to the drain line to lose prime. However, the safety function and indeed the entire function of the pool's drain system can be disabled by a short duration vacuum surge which occurs when the pump starts. The present invention suppresses the surge before it reaches the safety valve, thereby permitting the pool and the valve to function despite the presence of such short duration surges.
