FRENCH DRAIN CONNECTED TO GUTTERS
Many different types of Drains can be hooked together by one Drain Pipe. The Drain Pipe then running to an Exit Point makes up a Drainage System. One common type of Drain used in a Drainage System is A “French Drain.” Many times a French Drain is installed close to a building foundation or in a low area next to a home or business. This puts the French Drain in close proximity to Gutter Down Spouts. Rather than have water come off the roof and out the Down Spout and on to the ground below, many times it is much better to tie a Gutter Down Spout Directly into a French Drain or near by Drain Pipe depending on the Drainage System Design. Connecting The Down Spouts Directly into a French Drain is much more efficient and causes suction to occur in the French Drain. Connection of Gutter Down Spouts to a French Drain makes the Drainage System work better.
One Problem with connecting Gutter Down Spouts into a French Drain is overwhelming the Drainage System with too much water. Three Gutter Down Spouts is usually OK to connect into a French Drain. More than 3 Down Spouts can be too many. The Drainage System Design should also take into account the size of the French Drain and the Gutters. If you have a large long French Drain or over-sized gutters, the number of Gutter Down Spouts connected into the French Drain Should be reduced. This problem can usually be solved by increasing the size of the French Drain Pipe. This ususally means moving up from a 4 inch French Drain Pipe to a 6 inch French Drain Pipe. Four inch is the most common size of French Drain Pipe. If you have more than 3 gutter Down Spouts to connect, you should move up to a 6 inch French Drain Pipe.
