How deep to bury gutter drain pipe.

We found that the trench needs to be 10 12 inches deep with about a 2 inch slope. First thing first dig a trench. Continue until you have completed the trench. Along the entire area where you plan to install the drain pipes dig a trench around 12 to 14 inches deep.

While digging remember to make a slope that runs away from house. Depending on the trench length and more important the type of soil digging the trench with a shovel can range from relatively easy to downright impossible. Step 1 dig a 14 inch trench where you plan to run your corrugated drainage pipe. It is most effective to place a drainage pipe in the ditch at a depth of 12 to 18 inches and then fill the ditch with gravel.

Lay the downspout drain pipe in the trench. Make the trench the same width as the downspout pipe and about 12 inches deep. I settled on about a foot of depth enough to keep it well buried but obviously it will still freeze in winter. The trench should end at least 6 to 8 feet away from the home.

The trench should be at least 6 inches wide and slope down slightly 1 to 2 inches per length of pipe so water drains away from the downspouts. If your yard is flat or doesn t naturally have the desired slope dig the trench deeper as it extends away from the house to create the slope. Dig a trench about 6 inches wider than the drain pipe you plan to bury and dig the hole deep enough so that the drainpipe sits 3 inches below grade. Create a fall of 1 8 inch per foot of drain line.

Dig a trench along the desired route of the drain pipe. The deeper the trench you can dig the better. Weisman recommends extending the trench at least 8 feet from the downspout if there s available space. As a consequence the pipe trench will be quite shallow at the beginning and much deeper at the end.
