The Hayward SP209 acts as a barrier between important pool and spa systems and cold weather. Inserting the durable rubber stopper into an open pipe and twisting the inbuilt nuts along the bolt and washer system expands the device to give a tight seal. Keeping water out of pipes and equipment during winter months is crucial to preventing damage.
