We are working on the underground for a project where a remote building is to be protected by a pre-action system whose valve is in a different building 50ft away. The underground connecting these two buildings is to be part of the pre-action system (piping filled with air). In other words, the pre-action valve is in building A. The piping runs underground (after the valve) to building B.
This is a new one for us. My questions are what type of pipe do you use for this purpose and how do we drain the water out of the underground? I appreciate any info!
