Kin,

 

The N2 purge of the valve box is still on the technician’s to do list.  He hopes to have it done in a few days.  A few other items came up in the last 2 weeks.

Hi Paul,

 

Thanks a lot !   Have you also flushed nitrogen in the Valvebox ??   I remember Roberto mentioned wanting to do that some time ago …

Sorry, I forgot to send out a message.  Nitrogen flush was done the Friday before Christmas.  Two days of flushing with the spring relief on for safety. System was sealed on that Friday with the relief still in place.

Thank you,
