When the pressure vest is inflated you can disconnect the hand pump. If you need a replacement for the top part of the pump release valve you can order one here.
The pump release valve allows the pump to be disconnected after inflation. Fully depress the push button on the pump release socket and pull. The vest will remain inflated!
To inflate or deflate the vest, reconnect the socket by pushing it firmly over the plug until you hear a ‘click’.
