Karl,

 

If there is no cost difference, we would prefer Option 1.  We also think it will be less expensive than the others, but that is just a guess.

 

Thanks,

Clay,

Thank you for the response.  Is one of these options more preferred than the other?

Thanks,

Karl

Subject: Backflow Device for the Fire Line

 

Karl,

 

At the site visit yesterday it was determined that a backflow device is needed on the fire line.  This comment can be addressed by either:

1.      Removing the combination meter that is currently on the fire service and replacing it with a double check detector apparatus.  The meter on the device can be a Hersey or Neptune
disc meter and shall have either a touch pad or radio read transmitter.  If a radio read transmitter is decided upon, please contact Jerry Davis for specifics. 

2.      Placing a double check valve assembly on the fire line inside the building or exterior to the building in a new vault. 

 

In accordance with State regulations a design shall be submitted for the device by a licensed fire protection consultant.  The device will need to be installed and the fire line looped
prior to a CO being issued.  I will let Building Inspection know that Public Works is clear with proceeding with a permit for the renovations of the natatorium.

 

If you have any questions, please feel free to contact me.

 

Thanks,

Clay Barnett, P.E.
