1" rmc running up a colum, drain at bottom, tee's off with 3/4 sealtight in the top of a horn strobe (nema 4 rated). From the of h/s to the top of a pull station (nema 4 rated) with a drain in the bottom. Is considered exposed wet location. All threaded rmc and 3/4 ul listed sealtight and connectors.

1. Does this violate any codes for draining. They quoted 230.53, (but this is not a service) and also 225.22 (it is constructed to prevent rain entrance).

2. What does specified test conditions mean?

The 3/4" sealtite connector is a box connector, and would be illegal to put it in a tee with NPT or especially with some pipe reducer, which It sounds like you used.
 
Some of this I don't get, could you elaborate?

For starters, on jobs where drains are to be installed usually you are not allowed to enter the tops of boxes.

Perhaps this was a red flag to whoever cited you and they knew they didn't accept the work but weren't sure how to write it it up.

Is the drain in the bottom of the pull station box?

Who gave you the violation?

Just based on my own experience of feeding a box on a column in situations like this, the feed would run down the column, alongside of the box, below the box, then hit a T.
The bottom of the T will either continue down with conduit to a lower T to feed another box or have a drain fitting if it is the lowest point.

Out of the side of the T you nipple to an LL or LR then feed back up into the box.

I'm not suggesting these are/are not code requirements, just that on most projects I've done where drains were spec'd the install you described would be rejected by on site personnel or project engineers. ;)
 
It is a t-condulette. I agree, generally when you drain you do not enter the top, a general practice not a code issue.
