Downspout Drain. Underground Downspout Drain being installed. More commonly known as an “underground drain” because these drains are installed underground when the home is built. These drains direct the water underground and usually lead to the street or the sewer.
Some homes connect their gutter downspout drain to underground pipes. We call these gutter drains “underground drains“. The purpose of the underground gutter drainage is to re-direct the water away from the home, usually to the street or the sidewalk. Sometimes they even connect directly to the sewer line underground.
Underground downspouts are considered the more effective alternative to above-ground downspouts because they're easy to tuck out of the way. If you have a large lawn or just want to preserve the aesthetic of your landscaping, underground downspouts will keep your home safe without turning into an eyesore.
The Best Pipe to Use for Downspout Drain
We've looked at some of the best pipe options for downspout drainages and prepared this information to help you make an informed decision on what pipe to use for the downspout drain. PVC, or Polyvinyl Chloride pipes, is the best option for underground water drainage.
There are three main types of downspouts: K-Style, Round, and Rectangular. Each type has various advantages and disadvantages.
The trench must be at least 10-inches-deep, but be aware that in cold-weather regions the pipe occasionally will clog with ice during periods of heavy precipitation.
Downspout Elbows are attached at the bottom of the downspout. They are set at an angle so the water is directed away from the home. Elbows can also be used throughout the downspout to make it around corners, bump outs, and any other obstacles in the way of the downspout.
When they are not angled properly, water can flow back to the base of your home, causing significant damage to your home's foundation. Instead of attaching a tail to your downspouts, however, you should consider burying them.
Underground Downspout
Underground downspouts cost between $200 and $2,000 each. The premise of this yard drainage system is simple: The downspouts direct water away from the perimeter of your home and into a municipal drain or sewer.
The pit should be at least 10 feet away from the foundation wall. The bottom of the drainage pit should be above the groundwater level. You need to adjust the dimensions of the pit according to the volume of water that usually exits from the downspouts.
A downspout, waterspout, downpipe, drain spout, drainpipe, roof drain pipe, or leader is a pipe for carrying rainwater from a rain gutter.
Downspouts are the vertical drain connected to the eavestroughs that carries rain water away from the foundation of the house to prevent flooding into the basement. Smaller downspouts can carry water from an upper roof and direct it onto a lower roof for further dispersal.
Filters: Downspout Diverters are a family of devices which divert water away from the natural flow of a downspout toward the rainwater storage tank. Some downspout diverters provide a filtration function in addition to diverting the water. Some diverters also eliminate the need for a tank overflow pipe.
Installing a buried downspout system is an effective and low-maintenance way to protect your home's foundation and basement from damaging moisture. By routing the water away from the house, homeowners can prevent costly damage to their property.
The gutters must be clean to prevent clogging. The downspouts need to be extended away from the home a minimum of four feet, with six feet being preferred. When downspouts are connected to underground drains, it is very important to keep all debris out of the gutters, downspouts and underground drains.
Soffit is a large aluminum plate with small perforated holes installed under the outside edge of the roof, under the gutter. It has several functions: it protects, it is aesthetic and it allows ventilating the attic.
Description: Scuppers are used to provide an outlet through parapet walls or gravel stops on flat and built-up roofs to allow drainage of excess water. They can be used in conjunction with gutters and downspouts to divert the flow to the desired location.
Downspout: Water from the gutters moves vertically downward through the downspouts. Catch basin grate: Water exits the bottom of the downspout and runs through the catch basin's top grate. Catch basin: Water rises in the catch basin until it reaches the exit pipe.
The recommended depth is 14 to 24 inches deep depending on the type of pipe, its diameter, and how cold the winters can get.
PVC (Polyvinyl Chloride)
One of the widely used pipes for all drainage systems is PVC pipes. They are highly resilient and sturdy making them suitable even in the harshest conditions. Additionally, their durability ensures longevity-a major condition in underground systems.
Yard Drains. Yard drains are also called catch basins. As that name implies, the purpose of this drain is to 'catch' excess surface water in a basin and redirect it. The catch basin acts like a sewer drain and directs the water through a pipe sloping away from the basin.
