I hear you on the clay—total nightmare for drainage. When I did my own yard, I mapped out the low points first, then dug a trench about 18" deep, sloped it away from the house, and used perforated pipe wrapped in landscape fabric. Gravel on top, then backfill. The fabric is key; otherwise, the clay just clogs everything up. Took a weekend but made a huge difference. My only regret was underestimating how much gravel I’d need... those bags add up fast.

That’s spot on—skipping the fabric is a rookie mistake I’ve seen too many times. I usually spec a 4" perforated pipe for residential jobs, but depth matters more than people think. If you go too shallow, especially with heavy clay, you risk frost heave or roots shifting things around. And yeah, gravel... I always end up ordering bulk by the yard instead of bags, just to save the hassle. It’s surprising how fast it disappears once you start filling.
I hear you on the gravel—first time I did this, I thought a few bags would be plenty. Ended up making three trips back to the store. Learned my lesson. One thing I’d add: if you’ve got a lot of trees nearby, watch out for roots sneaking into the pipe over time. I had to snake mine out after a couple years... not fun, but better than digging it all up again.
Yeah, the gravel thing totally got me too—those bags look like they’ll go further than they actually do. I swear, my trunk still has dust from all those trips. About the roots, you’re spot on. I ended up putting a sock over my pipe and wrapping it with some landscape fabric. Not sure if it’s foolproof, but so far, no root invasions. If you’re going for that luxury backyard vibe, keeping everything tidy underground is key... nothing ruins a fancy patio faster than a soggy patch or a clogged drain.
