So after lunch, I'm walking back to my ancient brick office building,
where the basement also leaks when it rains, and what do I spy but a
new addition to the exterior!

So now I have some good pictures of what to do at my place!

Bit stark color wise (couldn't they have painted it to match the
concrete? <bg>) but yes, that will work. Note the size of the pipe,
yours may be smaller if it is draining a smaller area.

Well, that installation definitely gets high marks for generous slope

but............wow, it is ugly!

Definitely not something you'd want visible from the street.

Depending what color would be best for your installation you could use
black ABS, grey PVC or white PVC or even factory painted downspout.

It's the slope that's going to do the trick for you. Before spending
for new material just cut & raise the existing setup & see if it
works. For temporary trial you can block under the horizontal run at
the joints.

cheers

Good Pictures? Why not just use the pipe from the pic? :-)
