Thanks for the info. I guess what I'm looking for is something that states that all these existing double-check backflows are not a threat and replacing them all with RPZ is a lot of unnecessary extra cost for the owner. As Matt stated, it may very well be a losing argument as long as it has been "adopted". The info will be used to fight to keep the existing double-checks.> Date: Tue, 9 Oct 2007 14:10:20 -0400> From: [EMAIL PROTECTED]> To: [email protected]> Subject: RE: Double-check vs RPs> > Gayle, Perhaps our regulations in New Jersey would be of assistance.> > John Drucker, Fire Protection Subcode Official, NJ> ------------------------------------------------------------------------> ------> > STATE OF NEW JERSEY> > DEPARTMENT OF ENVIRONMENTAL PROTECTION> > BUREAU OF SAFE DRINKING WATER> > SAFE DRINKING WATER ACT REGULATIONS> > (N.J.A.C. 7:10)> > ADOPTED: November 4, 2004> > 7:10-10.4 Installation> > (a) The approved physical connection installation shall be> installed on the customer's side of the water meter on the> pipe(s) conveying the water from the public community water> system into a facility, shall be installed as close to the meter as> is reasonably practicable, and shall be prior to any other> connection, unless such other connection is also protected by> means of an approved physical connection installation.
