Virtually everyone has become a do-it-yourselfer, and downspout installation is no exception. The problem with doing it yourself, is that you have to know more than the simple steps to completing a project. Following these tips will help your gutter project go more smoothly.
Install When Putting on a New Roof
Timing your project to coincide with another large project may seem counterintuitive, but it will certainly make the process easier. Some experts would consider this to be the best time to install a new gutter system, including downspouts. Doing so will make the downspout installation easier, and will help your drainage system work better, because they will become a part of your entire roofing system.
Mind the Slope
Proper drainage requires some precision, in setting the correct slope toward your downspout installation. The ideal slope should be 1/2 inch, for every 10 feet of gutters. Where the gutter runs beyond 40 feet, the gutters should slant from a pitched middle. This means installing 2 downspouts, 1 at each end. The alternative is sloping toward the middle to a centrally located downspout. Either way, make this decision, and calculate the slope, prior to installation.
Avoid Negative Pitch
Just as it is essential to ensure proper sloping for water flow, it is necessary to avoid negative pitch. It occurs when shifting pipes or soil force the water to flow in the opposite direction. This can damage your foundation and soil around your house. To avoid this problem, make sure the outlet pipe is at least 5 feet from your foundation, and avoid installation in soil that has been tilled or otherwise disturbed.
