I have many I do as well, recent installations all seem to be AF an CPVC. Many have relief's instead of expansion tanks and many don't have proper test valves, sampling valves, etc. I do my best and write up what I see and sometimes they bite but more occasionally they'd rather buy new TV's. TD
I see this quite a bit in apartment buildings. We test the flow switch/bell through the ITC first. Then we test the A/F solution. We have several Residential group homes we inspect. The residents are developmentally challanged. Some of these homes have basements , ground floor only, 2 story and 2 story with a basement. Basements may or may not be occupied by residents at different times. One has a fire alarm systems, the rest have single station alarms. About 1/2 have antifreeze systems, and no way to test the antifreeze protection. Piping is plastic and copper, plastic and iron, or all copper. None have isolation valves between the backflows and the downstream piping. Is there a standard other than 25 for testing and inspection? _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
