Advice on locations of drum drip for a dry-loop system
(OP)
Hi guys,
I attached a sketch of the dry-loop system that I am working on. Its my first time working on a dry-loop system in a parking garage and need your help how to locate drum drip to this type of layout. Thanks in advance.

-The pipe elev. is -57'-0" AFF (below grade), this is P6 parking level
-Trapped sections, that is what I want to know.
The client/customer is asking me the locations so that they can send to the electrician to set up the power for the electrical tracing.
You think you can give me your opinion the locations of the drum drips?
Thanks so much!!

sounds like you are trying to do "heat trace" ?????

Are they planning on heat tracing the drum drips to prevent any collected condensation from freezing?

For dry systems, you have to install the branchlines pitched 1/2" per 10 feet so the water drains back to the main. Then the main has to pitch 1/4" per 10 feet back to a drum drip. To detemine where to put your drum drips, you have to figure how much vertical room you have between your high points and your low points. If you have 6" of vertical movement for your main, you can theortically have 240' of main sloped toward the the drum drip on one side, and 240' sloping to the drum drip on the other side. Watch were the main high-point and low point puts your outlet elevations for the branch lines. The main will be the branch line LOW POINT. At the main high point you'll need to make sure you have enough room at your branch line high point so the deflector is still below framing as required. At the main low point, make sure your branchline deflector isn't too far below the framing or you'll need a sprig. Not a big deal unless you fabbed the branch lines with 1/2" or 3/4" outlets. Based on this information, you can see your sketch is lacking the information needed to provide a solid location(s).
