Question about a French drain. Wrap the pipe or not?

I have a simple DIY project. I have an 8’-10’ section of yard that needs a French drain spur. I already have a basin in place to attach the pipe to. When I look at YouTube videos, half say don’t wrap the pipe with a sock or any fabric, some say use landscaping fabric and wrap around the rocks and pipe and the rest advocate either socks or fabric.

After I lay the pipe in rocks I’ll be covering the pipe with rocks and leaving it that way, so there will be no sod put on top of the pipe. The pipe will be surrounded by rocks and that’s it. Do I need any sort of fabric or not?

Any advice is appreciated

I've seen it done both ways.

Most people that do it for a living recommend wrapping the entire ditch, rocks, pipe and all.

Many say only the pipe being wrapped will allow silt to clog the gravel over time.

If I was doing it I would lay the cloth in the ditch prior to backfill and pipe and then overlap the top before you make the last lift of dirt and sod.

That’s the happy medium option I was thinking about doing.

Lay fabric, put pipe at bottom of trench, cover sides and top with rock, wrap it all up with the fabric. I’ve been researching this EXTENSIVELY for about 2 months and seems all the experts are doing it this way. Many of the specifically mentioning NOT to only wrap the pipes because soil, sand and/or dirt will eventually move through the rocks and cake on the fabric therefore not allowing water to properly enter into the pipe. Seemed to make sense to me.

Is the drain to help with general yard water, a low spot, or actual roof water?

Is your basin the source of water, or an outlet for overflow?

If at all possible, I prefer solid pipe to an exit, but true French drains do have a purpose sometimes.

The area that holds water near the corner of my yard. The basin is an outflow.

Look up Apple Drains channel on youtube. He has tons of very helpful videos.

Also, and you probably already know this if you've been researching, but put the perforated side of the pipe on the bottom.

Speaking of French drains, what is the best way to clean these things out? Had a tenant who didn't keep these clean and allowed dirt to block it and now it is full of dirt inside. Is it destroyed or can this be recovered?

Not saying this is the best way but I use a clog hog to clean/clear my lawn underground drainage pipes of accumulated sediment/debris. LINK.

Almost word for word what my landscaper told me last week. And he does a ton of them.

Interesting side note. I had him redo some existing drains my dogs dug up and chewed up. Said he’s seen quite a bit of this, the theory being that the black plastic flex stuff used for conveying water from gutter downspouts and such are being made from post consumer plastic and there’s enough food/oil/whatever smell left in the plastic to be attractive to dogs. We can’t smell it but they can. Knowing all this stuff is manufactured at a pretty low melt and molding temperature it sort of makes sense. Green engineering strikes again.
