Check that; it's a low suction sensing and the the primary pressure sensing line? Disregard my earlier comment.

It is a low suction sensing line, installed on the system side of the backflow. I thought they should be installed city/ supply side, apparently I am incorrect. I thought the sensing line would not be effective on the system side, because you could have the city main shut down and still show pressure on the system side of the backflow. -----Original Message----- From: [email protected] [mailto:[email protected] <mailto:[email protected]> ] On Behalf Of Tom Duross Sent: Saturday, December 05, 2009 2:49 PM To: [email protected] Subject: RE: pump sensing line So you're saying the sensing line is on the pump suction from the backflow? And you were originally asking if it should be on the backflow supply from the street? Tom The backflow is installed on the supply side of the pump, city side. The sensing line is installed system side of backflow. I'm surprised that the BFP was allowed on the system side of the pump at all but since the sensing line is for pressure drop in the system having it there (and allowing it as Tom says from the TIAs) makes sense. > > I saw a pump recently with the sensing line installed on the system side of > the backflow. > What is the reason for installing on the system, rather than the city side > of the backflow? > Am I correct that it should be on the city side? > > Forest Wilson _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum <http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum> For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum <http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum> For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) __________ Information from ESET NOD32 Antivirus, version of virus signature database 4662 (20091205)__________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com <http://www.eset.com> _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
