Step-by-step explanation:
Downspout extensions should extend at least 6 feet away from the house. This helps to ensure that rainwater is directed away from the foundation and prevents potential water damage to the house. Extending the downspout 6 feet or more allows the water to flow away from the house and helps to prevent basement flooding.
