"adding a good layer of coarse gravel around the drain pipe before wrapping it with fabric"
Good tip—I did something similar when I tackled drainage issues around my patio. Definitely noticed less clogging afterward. One thing I'm still unsure about is how thick that gravel layer should ideally be... I've heard everything from a couple inches to nearly half a foot. Curious what thickness you settled on and if it made a noticeable difference?
I went with about 4 inches of gravel around mine and it's been solid so far. From what I've seen, less than 2 inches can get overwhelmed pretty quickly, especially if your soil doesn't drain well. But honestly, going beyond 6 inches felt like overkill (and a waste of money). I'd say anywhere between 3-5 inches hits that sweet spot—enough to keep things flowing without breaking the bank.

Totally agree with you on that sweet spot. I've found around 4 inches usually does the trick for most of my projects too. But I have to say, soil type can really throw a wrench in things sometimes. Last year, I worked on a build where the soil was heavy clay, and even at 4 inches we had some drainage headaches after heavy rains. Ended up adding a French drain system later on, which wasn't exactly fun or budget-friendly...
Curious if anyone else has had to deal with tricky soil conditions? Did you stick with gravel adjustments or go for something more creative?
I've usually found 4 inches works fine too, but honestly, when dealing with clay-heavy soil, sometimes it's better to bite the bullet and go deeper from the start. Gravel adjustments can only do so much if the water has nowhere to go. On my last project, we ended up excavating a bit deeper and layering in some coarse sand beneath the gravel—made a noticeable difference without needing a full French drain setup.
Good point about the sand layer—I've seen that work pretty well myself. Still, I'd caution against relying solely on sand if drainage is a serious issue. Clay soils can be stubborn, and sometimes even sand layers get saturated if there's nowhere for water to escape. If you're already digging deeper anyway, it might be worth considering a simple perimeter drain or at least making sure your site grading directs runoff away effectively. A little extra planning upfront can save headaches later...
