I hear you on the dual-flush headaches—sometimes those retrofits just don’t play nice with older plumbing. I’ve seen a few rain barrel setups feeding toilets, but honestly, integrating them indoors can get tricky, especially if your pipes are finicky or you’re dealing with low pressure. Greywater’s a whole other beast; filtering and routing it safely isn’t always as straightforward as the DIY guides make it look.
One thing I’ve noticed is that older homes sometimes have cast iron or galvanized pipes that just don’t love the extra debris or sediment from rainwater systems, even if you filter. Have you checked what your main lines are made of? Sometimes a simple inspection can save you a lot of hassle down the road.
Curious if anyone’s managed to retrofit a greywater system without running into code issues or constant maintenance. I’ve seen some creative workarounds, but not sure how they hold up long-term...
Had a similar situation when I bought my place last year—pipes turned out to be a weird mix of old galvanized and newer PVC, which made even basic low-flow toilet upgrades more complicated than I expected. The dual-flush kit I tried first leaked constantly, and the plumber said it was partly because the internal tank hardware just didn’t line up with the older design.
Looked into rainwater for flushing too, but between local plumbing codes and the sediment risk, it felt like more trouble than it was worth. I did have a neighbor who went all-in on greywater for irrigation, but he’s always out fiddling with filters and cleaning out pipes. From what I’ve seen, the maintenance side can get pretty tedious unless you’re ready to keep up with it.
If you’re dealing with mixed pipe materials or anything pre-1970s, getting a pro to check things over is probably worth it. Sometimes the “easy” sustainable upgrades turn into a rabbit hole once you open up a wall or two...

Yeah, mixed pipes can be a real headache. I hear you on the “easy” upgrades turning into a mess once you start digging in—seen it happen more than once. Honestly, sticking with pro advice is smart, especially with older setups. Worth the hassle in the long run.
I get where you're coming from about mixed pipes and old setups—seen my fair share of “quick fixes” turning into full-blown projects. But I’d push back a bit on the idea that pro advice is always the only route, especially for sustainable upgrades. Sometimes, overhauling everything at once isn’t necessary and can even introduce new problems.

That’s true to a point, but I’ve found that careful planning and sticking to reputable materials can make DIY sustainable upgrades manageable—even in older properties. For example, swapping out aerators or installing dual-flush kits doesn’t usually require a pro, and the maintenance is pretty minimal if you stay on top of it. I always double-check local codes and make sure any changes won’t mess with insurance or safety standards, but I’ve had good luck handling smaller upgrades myself.
Long story short, not every improvement needs to be a big ordeal with contractors involved. Sometimes it’s just about knowing your limits and not biting off more than you can chew.
I hear you on not needing to call in the cavalry for every little thing. There’s a lot you can do yourself, especially with the right research and a bit of patience. Like you said:

That’s spot on. Stuff like low-flow showerheads, faucet aerators, or even those simple leak detectors are pretty straightforward. I’ve seen plenty of folks handle those upgrades just fine, even in houses with some “character.” The trick is knowing when you’re out of your depth—old galvanized pipes or anything behind walls can get messy fast. I’ve had to fix more than a few DIY jobs where someone thought they could swap out a valve and ended up with a slow leak inside the wall... not fun.
One thing I’d add: always keep an eye on water pressure after any changes. Sometimes those eco-friendly fixtures can drop pressure more than expected, especially if there’s already buildup in old lines. Had a neighbor swap all his faucets and suddenly his shower was barely a trickle—turned out he needed to flush the lines first.
I’m all for folks tackling what they can, just as long as they’re realistic about what’s involved. And yeah, double-checking codes is huge—some places are stricter than others, and insurance can get weird if you ever have a claim.
Bottom line, sustainable upgrades don’t have to be a headache or cost a fortune. Just take it step by step and don’t be afraid to call in help if something feels off.
