For several reasons, i only want one downspout in this run, and need it to come out in the middle. Here is a rough diagram:

Section A is easy enough... just slope it down from left to right, but what should i do for section B?

Make the gutter all one length, attach it starting from the left, slope down until i get to the downspout, and then slope the rest of it up untill it ends on the right?

OR

Make section A one piece, with the downspout on the right side... attach it sloped down left to right as normal, and then attach section B and slope it up to the right?

Or some other method?

Thanks for any help. Worst case scenario i could move the downspout all the way to the right, and then just slope the whole thing down... OR i could eliminate section B all together... but the optimal scenario is how i have it drawn.

Thanks for any help.

Need a real picture of your home to see why you need it done that way.
That drawing is no help.

I can post it, but i thought the question was pretty straight forward. If a downspout is in the middle of a run, what is the best method to get each side sloped correctly?

Here is the picture. I know that I am pushing things by only putting 1 downspout in for ~45 ft. of gutter, but that's how i would like to do it right now. I'm going to use a 3x4 downspout.

The reason i have the spout in that location is because i am going to connect the downspout to 4" PVC and run it underground out to a drainage ditch. The reason i dont want the downspout on the left end of the house, is because that would put the PVC pipe into a section of the drainage ditch that would be overwhelmed with the additional runoff.

The reason i dont want the downspout on the right end of the house is because there are huge tree roots between that location and the drainage ditch, and i dont really want to have a bunch of bends in the buried pipe, to reduce the possibility of clogs... although i suppose if i installed a wire mesh guard over the downspout hole, it might keep all of the debris out of the buried pipe. In that case, i could just put the downspout on the right end and it would just slope down left to right as normal.

Best way is where i have it though, because it's a straight shot out to the drainage ditch from that spot.

Thanks.

Since it looks like you have a compacted gravel driveway, I would sill put the downspout on the left. Bring it out from the home , run it across the drive way at an angle to the drainage ditch

Your entire dilemma is based on the assumption that the entire gutter trough must be perfectly straight. And then tipped down one direction or the other toward the down spout.
But in actuality a 45' seamless trough will flex quite a bit. You can use the flex to achieve the need slope. For example If I were installing a 40' trough with a down on each end. I attach the center 10 feet first level. Then pull each end down about 1/2 to 3/4. Now I have equal amounts of water running into each trough.
For your application just reverse slope. Attach your ends first. And pull down the area where you want the single down spout.

Not sure how the pros do it. Just how I have always done them,
good luck

Thanks guys.

Ztman thanks, but im trying to avoid digging through the driveway.

Yodaman that all makes sense, thanks a lot. I will make it all one length and then either tack the middle first and push the ends up, or tack the ends first and pull the middle down like you said. Thanks.

Attach the middle first. Supporting in the middle the entire trough is stable.
Supporting long troughs on the ends only could cause the center to buckle and kink.

In case you lost track you asked this a few days ago in another thread.

//www.diychatroom.com/f9/advice-basic-gutter-install-346825/
That's strange, i have email alerts set up for threads i start here (and on other forums) and that's the only way i access threads that i start... i click on them when i get an alert that a post has been made. For some reason i didn't get any email alerts for the other thread, or else i somehow deleted them or something, so i was under the impression that no one had posted in it. I now see that this question had been answered in it... mods can delete this thread if you want.
