Previously, when I would insert a PDF in AutoCAD, I would get a nice clean conversion, with everything editable: All the lines were clean and sharp. Recently when I try to Import a PDF it converts like this: And the lines are not sharp: We did switch from Adobe to Nitro a while back...

I have not, but now I want one!!!

I have heard a few old timers refer to Riser Checks a "straight gut" valves. But I am in the Pittsburgh area. None of us speak the Kings English [wink]

I agree with the above 100%. This is not the way I would do it. Although, as I stated above, I have seen it required in Pittsburgh a couple times. One attachment shows them being used for a window near a property line (buildings were only a foot or two apart). The other attachment shows...

@cdafd I have seen this required in the Pittsburgh area. And the reasoning I was given: to prevent the glass from blowing out onto somebody trying to use the fire escape?

@sprinklerdesigner2 you said your job has OPEN wood trusses, yet the quote from the submittal mentions SOLID wood joists or trusses. doesn't sound like apples and oranges?

I had a similar situation on an open parking garage we did a few years ago. The building was built 5 feet off the property line, and the AHJ made us add a water curtain to the open side closest to that property line.

Ok, so I recently had an engineer and an uncertified sprinkler "designer" tell me that NFPA states when performing hydraulic calculations, you need to end up with a cushion of 7 psi below your water source? I have scoured my copy of NFPA 13, and I do not see where this is stated? I think they...

That was part of my point Travis. I was arguing with my co-worker that it did not apply to all dry systems. He argued otherwise.

I believe this issue has been brought up on here before, but I can't find the thread. NFPA13 states that galvanized piping must be used in a dry system (NFPA13 2013ed. 8.4.7.2), however this is listed in the section 8.4.7 CMSA Sprinklers. So, if I read that correctly, this only applies if you...

FireTech, for sure...

I love when other contractors use Schedule 7, because, much like NewtonFP said, it rots out fairly quickly. We have replaced a TON of it in the past few years, and most of it wasn't that old. Personally, we only use schedule 10 & schedule 40. Saves having to worry about getting called back to...

I agree with Travis, depending on the size, I would typically use a dry sidewall in this application.

I work from home from time to time, although it is company work, not side work. At the office, we have a subscription seat for AutoCAD, and I use HydraCAD as well. AutoCAD lets you use their product on more than one computer, but only on one computer at a time. HydraCAD can be used on any...
