Patent abstract
A pump and alarm control promotes water safety and prevents entrapment in swimming pools, spas, and water features, such as fountains and waterfalls. The pump and alarm control monitors the vacuum on the influent side of a pump for the pool, spa and/or water feature and a two speed pump for a spa and automatically detects blockages in the pool, spa and/or water feature drains. The pump and alarm control is capable of detecting entrapment and blockages in different and distinct normal pressure operating conditions. Upon detecting a blockage the pump and alarm control shuts down pump operations and activates audible and visual alarms.
