I get where you’re coming from, but I’ve actually had better luck with perforated corrugated pipe wrapped in a heavy-duty sock, especially for those longer runs. It’s not perfect, but it’s a lot less disruptive to install if you’re trying to keep the yard intact. Solid pipe and gravel is great for driveways or spots with cars, but for garden beds or rain gardens, I’d rather keep things a bit more flexible and minimize the amount of gravel going into the ground. Less mining, less hauling, less waste… just feels better for the planet, even if it means cleaning out the ends every couple years.
I totally get wanting to avoid hauling a ton of gravel—my back still remembers the last time I tried that. When we redid the side yard, I went with the sock-wrapped corrugated pipe too, mostly because it was cheaper and way easier to snake around the flower beds. It’s true, I have to flush it out every couple years when the ends get gunked up, but honestly, I’d rather do that than tear up the whole yard again. Plus, less gravel means less money spent at the garden center... and more left for actual plants.
I’m right there with you about the gravel. When we moved in, I thought I’d be all “DIY hero” and do the classic French drain with gravel and pipe. Halfway through, I realized I’d underestimated just how much gravel weighs—my arms were noodles for days. Ended up switching to the sock-wrapped corrugated pipe for the back garden, mostly because it was flexible enough to dodge around the tree roots. Haven’t had any major issues yet, though I do notice some slow drainage after heavy rain. Maybe I should try flushing it out like you mentioned... I’d rather do that than dig everything up again.

That flexibility is a lifesaver, but I always wonder about long-term clogs. Have you ever actually tried flushing it out? I’ve seen those “drain cleaning bladders” people hook to a hose, but I’m skeptical they do much if there’s a lot of silt. Also, did you slope the pipe enough? Sometimes slow drainage is just a grade issue, not a clog.

You’re right, the sock helps with roots and silt, but it’s not magic. I’ve used those drain bladders a couple times—sometimes they work, sometimes you just end up with a muddy mess. If you’ve got a good slope (even just an inch per ten feet), that’s half the battle. Honestly, I’d rather deal with flushing a flexible pipe than digging up a rigid one any day.
