facts:
1. the gutter is flat, or very near flat.
2. flow in the gutter is open channel.
3. Manning's formula for open channel flow is: 
.
.
4. if the slope (S) is 0, then the velocity (V) is 0 and the flow in the gutter (Q=V*A) is 0.
5. if the slope is 0.0014, then the square root of the slope is 0.037. the velocity and flow in the gutter are very small--near zero.
6. if the gutter is full, and the slope is 0, or near 0, then all or most of the water coming off the roof overflows the gutter.
7. there are two outlet pipes from downspouts--mine and my neighbor's.
8. the pipe on the right is buried. look closely--only a small part of the top can be seen.

10. if the open end of the pipe from the downspout is buried, with nowhere for the water to go, then water backs up in the plastic pipe from the downspout.
11. when the plastic pipe from the downspout is full, then water backs up in the downspout.
12. when the downspout and the gutter are full, then water coming off the roof flows over the gutter and washes out the ground beneath it.

16. the builder says that the plastic pipe is not buried. fact: the plastic pipe is buried. (in other words, "don't believe your lying eyes".)
17. fact: the buried pipe looks the same today as the day that we bought the house.
17. fact: the buried pipe looks the same today as the day that we bought the house.
18. the builder says "it's not our problem."
19. fact: the builder created the problem by installing the gutter level, or near level.
20. fact: the builder may have created the problem by installing a gutter that is too small for the roof area and rainfall intensity.
21. fact: burying the outlet end of the plastic pipe created the problem.
22. fact: we did not bury the outlet end of the plastic pipe. it was buried the day that we bought the house.
23. fact: the builder created the problem.
19. fact: the builder created the problem by installing the gutter level, or near level.
20. fact: the builder may have created the problem by installing a gutter that is too small for the roof area and rainfall intensity.
21. fact: burying the outlet end of the plastic pipe created the problem.
