What happens when a drain is flat?
No Slope: When the pipe is completely flat, water requires more energy to move through the drain.

Pooling can occur, increasing the retained water within the drainage line. This kind of pooling can be extremely problematic as it attracts one of the most detrimental things to drains... tree roots. Tree roots naturally seek out moisture in order to promote growth and are attracted to the standing water in your drain. Once roots enter the system they will block flow and reduce effectiveness.#N#A properly built French drain that has low spots and retains water will NOT stop tree roots. These roots can and will gradually grow through the fabric destroying the integrity of your system as they seek moisture. Its important that all of the water is able to dissipate, avoiding the invasion of roots, vermin, and bugs.#N#Negative Slope: A less common but still undesirable pipe position is when the trench and/or pipe has a negative grade. This condition makes it impossible for water to flow through the pipe. The water table in the ground has to rise to a high enough level of saturation in order for it to flow through the system. Negative slope in your drainage pipe is bad if the goal is to drain away from a building as the negative slope can draw water back towards a structure or foundation, making things worse.#N#Good Slope: Greater than 1% grade slope is ideal for your trench. This will allow water to drain away from the inlet and ensure gravity does all the work to distribute it along your drain lines.
