Recently on a property survey, I observed both pendent and upright sprinkler heads in the same branch that too in same vertical plane. Wondering what could be the reason? Can anyone help?
Could be obstructions to the spray pattern of the upright sprinklers?
Yes Harrit I too agreed. Also it could be obstruction of pendent sprinkler and its spray pattern.
Thanks Harrit and Sandip.
It looks like this was done as a provision for false roof ceiling protection (above and below). But the false ceiling was never constructed though the sprinkler heads remain. I think a possible solution to prevent what you gents have identified as an issue is to temporarily remove the pendent heads and block the openings. Reattach the heads when the false ceiling comes up.
