Gentlemen,

 

I wanted to make you aware of what I found re: this service.  As you know, when the fire DCVA was installed on January 25, 2011, there was a Badger meter on it and the reading was 0.
 On February 15, it was replaced with a Hersey meter, reading 0.  When I was in the mechanical room yesterday for the domestic RPZA testing, I noticed that the fire bypass meter was
in backward (arrow pointing opposite the direction of flow), and the reading was 9998780. This would indicate that 1,220 gallons were registered backward.  I further noticed that the
#2 shut-off on the bypass was closed!  I brought this to the attention of Rodger Harrison, the superintendent for Andres Const. and his fire sprinkler subcontractor.  They responded
that it would be remedied immediately.  When I went back for the flushing of the domestic RPZA and subsequent re-test, I observed that the fire meter was re-oriented correctly and the
shut-off valves were both open.  The reading was now 9998870, indicating that 90 gallons had gone through the meter since yesterday.  (I also had the sub-contractor install brass plugs
in all the test cocks).  When billing this account, we must remember to bill for the 1,220 gallons of backward flow, then the 1,220 gallons of now forward flow to get the register back
to 0, plus whatever goes above 0.  This does not take into account that the #2 shut-off was closed for an un-knowable amount of time between 2/15 and 4/27.  The usage is from a couple
hoses connected to their fire protection system.  They have been using that for construction work inside the building.  

 

As far as the domestic service is concerned, the RPZA finally passed after “flipping the disc” on the #1 check.  The valve outside the vault is closed (Debris cap is in place), the bypass
inside the vault is closed, and the two mainline isolation valves in the vault are open.  At some point, Tri-Dal (or their sub) will re-set the meter to be in front of the spool piece
of pipe, and tap it for a test-port.  If service is connected before they do that, they would have to open the bypass to maintain service to the building.  I will let you know when they
contact me to do that work so that you can operate the valves for them (unless you want to let them operate them under your supervision).  A ladder is needed, and they should be bringing
one. Hope this all makes sense.  Let me know if you have any questions.
