How to Extend Downspouts Underground How to Extend Downspouts Underground
If you have downspouts in your home you may want to extend them. Downspouts are needed to make sure that water that come off of your rain gutters properly drains away from your home. If your downspouts are too close to your home this may result in a pooling of water around and near the foundation of our home. This will result in possible flooding, especially if your home does not have a sump pump or if the basement is prone to flooding issues.
This article will explain the steps and process needed to extend the downspouts for your home.
Step 1: Purchase Downspout Extension
You will need to go to a home improvement center or other retailer that sells home renovation materials and purchase the downspout extenders for your home. Prior to purchasing the downspout extensions, you need to determine where you want the water from your roof to drain to. If possible you should build the extension as close to the street as possible in order to allow for the water to be drained into the open sewers near your home.
Step 2: Dig a Trench for the Downspout Extension
Use a ditch digger or shovel and dig a trench that runs from the current downspout to the spout where the downspout extension will stop. The depth and width of the ditch should accommodate the size of the extender that you purchase for your downspouts. Typically the extenders are made from a rubber or plastic material and are black that look like ribbed tubing. You may also have purchased a straight pipe that is made from the same aluminum material as the existing downspout.
Step 3: Connect the Hose to the Downspout
Connect the black ribbed hose or rigid downspout extender to the existing downspout to the gutters. Make sure that the connection between the downspout and the extender is snug and secure. Use a collar or connector if necessary to secure the extender to the downspout and lock it in place. If the connection between the downspout and extender are not secure you may run into a situation, particularly if you experience a heavy rainfall, where the connection will come loose and your basement will become subject to a potential flooding situation.
Step 4: Bury the Extender Underground
With the connection between the extender and the downspout secured and in place, you need to use the ditch digger or shovel to cover up the hole. The hole should completely cover up the extender when covered with the dirt. Have some additional dirt available if you need it in order to plant grass seeds to replace the sod that was torn up. You can also replant the sod if it were dug up carefully or replace it with new sod.
Water the area where the downspout extender was buried and you have completed this project.
