The NO FLOOD EZ PLUG is designed to be used inside an existing drainpipe or to be installed on new drains. This back flow water device is easy to maintain. 

No digging is necessary. They are installed in the up right position with the removal of an entrance cap and are always exposed for easy maintenance.

The EZ Plug can be installed with an O-ring or by placing caulk around it, after sliding it into an old existing sewer pipe.
