If you did not put in “check snoots’, or check valves behind each in this configuration, then the water is circulating back thru these to the truck.

Standpipe test has failed 3 times and now they’re thinking water is circulating through these valves back to the fire truck. Anybody ever run into something like that? _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2flists.firesprinkler.org%2flist%2fsprinklerforum.lists.firesprinkler.org&c=E,1,QdrGtBJFnnMBq_MxxAdgeDYtz-kB_ImE1v644LM95k3pSsbZhpAHkfzIxbBAEvQOzAsUrBdDYj-raGtp4ztl31D075dEqruopd_bL_eyWLv3BqFlGtN8gw,,&typo=1> To unsubscribe send an email to [email protected]<mailto:[email protected]> _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2flists.firesprinkler.org%2flist%2fsprinklerforum.lists.firesprinkler.org&c=E,1,F04Y1ZsNJgEjoZu26JrpArvpNnpn1VQia8Y3DEJHhsrTlB4WnFHgA8B3i090VyRlIGM0B5CwQ8xn5n1odIP1gauEpZQcxaN4zdCw95t6VA,,&typo=1&ancr_add=1> To unsubscribe send an email to [email protected]<mailto:[email protected]>
