Cover with Gravel and Filter Fabric Cover the pipe with about 3 inches of gravel or crushed stone, but not enough to cross above ground level. filter fabric over it for another layer of protection.
Once the drain is finished place a 2” layer of Stone on top of the French Drain. Then add another layer of Weed Mat across the French Drain then add a 2” Layer of Diamond Sand followed by Weed Mat and at least 4” of Top Soil.
Yes the trench should be lined with fabric. A fabric lined trench is better than a sock because larger surface area means it will take longer to clog.
The sole purpose of a drain cover is to prevent environmental contamination. You have to realize that any chemicals or hazardous materials which travel down the drain end up somewhere — usually in the closest body of water. Rainwater typically carries through drains to the nearest lake, stream or ocean.
Covering them helps prevent infestation, which can lead to health violations and customer complaints. Maintaining Hygiene: Open drains can emit foul odors and harbor harmful bacteria, mold, and pathogens.
Plumbing vents prevent the siphoning of water from traps by introducing fresh air into the drainage system. This air circulation breaks the vacuum effect and maintains the water seal in the traps.

Always Use Filter Fabric for the Best French Drain
And the longer you have your system in, the better the soil filter zone that's formed becomes.
If installing the drain involves diverting a stream or affecting a wetland, you likely need a permit to move forward. Generally, a small French drain on your property that doesn't change the flow of runoff entering and exiting your yard won't need a permit.
To get the proper function out of French drains, the trench must be lined with drainage fabric. This material prevents clogs by keeping dirt and debris from seeping into the system through the ground.
Clay soil has poor permeability, meaning it doesn't allow water to pass through easily. In such cases, the effectiveness of a French drain may be limited as the water may struggle to drain away from the area efficiently. French drains may not be suitable for areas with high water tables.
Just like other types of drains, they are susceptible to clogging over time. Ideally, clean the French drain once every year.
Clogging and Blockages
Clogging is one of the leading causes of French drain failure, often due to root intrusion or sediment build-up.
If you want to ensure your system continually performs for decades to come then be sure to line your trench with professional-grade non-woven geotextile drainage fabric using the "Burrito Wrap" install method.
Importance of Drain Covers
The significance of drain covers can't be overstated, especially when it comes to safety. They're crucial in preventing falls and accidents. Imagine walking along your local high street and unexpectedly stepping into an uncovered drain – it doesn't bear thinking about!
A covered French drain has grass or some bed material over it, but an open French drain is a French drain where you excavate out all the dirt; align the trench with the fabric; put the pipe in it, and then you fill it full of stone.
The purpose of closed drainage is to prevent direct exposure of harmful waste to humans. Closed drainage systems can prevent the accumulation of stagnant water, thus avoiding mosquitoes breeding.
If you're experiencing invasive odors in an infrequently used bathroom, your issue may be simple: the water in the P trap has evaporated. All you need to do is run water in the sink or shower for a few minutes, and the issue should resolve!
Sewer Drain Should Hold Water
For example a toilet pan has water in its bowl always this is to prevent foul smells entering the building. Other examples could be the J trap or shower drain these are also designed to hold water during normal operation.
