Sanitizing Water Lines after BWO is lifted

Looking for some info on if you MUST sanitize water lines after a boil water order is lifted.

We currently flush all lines for 15 or 30 minutes depending on the size of the water tank.  

We then replace all filters (whole restaurant & point of use)

We then have all equipment washed, rinsed and sanitized. 

It recently was discussed that we are not properly sanitizing the whole water line. Since we change out the in-line filter after flushing, then WRS the equipment, the line between the filter and the equipment is not being sanitized. It was recommended to use a JT Flushing/ Sanitizing Cartridge. 

Hi Weebus90,

My preference would be to sanitise if at all possible. Guidance is to empty the tanks and flush the system out.

Example Guidance for Food Establishments before, during and after a Water Advisory or Flood

How are you going to check your water is safe at point of use before restarting operations?

Kind regards,

Tony
