Minimum sprinkler seperation
Minimum sprinkler seperation
(OP)
So do you measure a straight line, like branch line to branch line?
Say you measure straight line and you are closer say that six feet is the minimum, but one sprinkler is to the side/ at an angle to the other sprinkler.
Take the same set up and measure on the angle to the head, and it is greater than six feet, measured that way.
I know what 13 says, but I have heard people measure both ways

That's how I look at it, but your question is a tad unclear to me.
RE: Minimum sprinkler seperation
13 says for minimum spacing,six feet for normal sprinklers, you measure sprinkler to sprinkler.
But if one sprinkler is where the X Is
And another is where this X Is
Say the distance between the two "is" is 5' 10"
But the distance at an angle between the two "x's is 6'2"
Do the two X sprinklers meet the required six feet minimum separation??

RE: Minimum sprinkler seperation
But there was discussion do you measure sprinkler to sprinkler or a straight line, like branch line to branch line.
Will pass nighttime reply on to the discussion and since that is how 13 reads, seems like correct answer
thanks
RE: Minimum sprinkler seperation
You have a sprinkler at 0,0. Then, you have a sprinkler at 5',5'. Using the properties of a right triangle, the sprinklers are actually 7.1' apart on the diagonal.
Do you go by the 5' or the 7'. The sprinkler doesn't care how it is connected. It just matters that it is no closer than 6' to another sprinkler so there is no "cold soldering" of the adjacent sprinklers.
I had a similar situation many years ago, but the reverse. I had sprinklers spaced at 14' on center in a ceiling grid. But the structure was at a 45° angle to the ceiling grid. As such, my piping was run so that the sprinklers were connected where the pipe was 14*Sqrt(2) or 19' between fittings. Now, the sprinklers were on a complete 14' grid spacing. It was just that the piping was run on an angle. It took a face to face meeting to get the authority that was reviewing the plans to see the concept.
