need some advice on setting up a rain harvesting setup at home

Honestly, I get the appeal of adding another filter, but from my experience, it might just complicate things. Tried something similar last year - ended up spending more time cleaning the filter than I ever did scooping sediment. Maybe simpler really is better sometimes?

I see your point, filters can definitely be a hassle sometimes... but it really depends on the setup. I've found that if you go with a mesh pre-filter that's easy to access, it cuts down on the maintenance quite a bit. Last year I switched to a basic stainless steel mesh screen - nothing fancy, just something I could quickly rinse off every couple weeks - and it made a noticeable difference. Not saying simpler isn't good, but sometimes a minor tweak can make complexity manageable.

Good point on the stainless mesh - definitely helps if you keep it accessible. A couple other things I've noticed:
- Slightly angling the mesh screen can help debris slide off easier, less buildup overall.
- Checking after heavy rains makes a big difference, too... prevents surprise blockages later.

Good tips on angling the mesh, hadn't thought of that one. I'd just add - don't underestimate how quickly debris can build up, even with a good screen. Had a tenant once who swore he checked regularly... turned out his "regularly" was maybe once a season, if that. Ended up with a pretty nasty overflow during a heavy storm, and guess who got the call at 2 AM?

Also, stainless mesh is great and all, but I've seen some cheaper plastic screens hold up surprisingly well too. Might be worth experimenting if you're trying to keep costs down. Just don't go too cheap - you'll regret it when you're fishing bits of cracked plastic out of your gutters later.

One last thing: make sure your overflow setup is solid. Even with diligent maintenance, you'll eventually get that freak storm or unexpected blockage. Better safe than sorry...

Good points about overflow setups. Had a client once who insisted his system was "bulletproof" because he splurged on stainless mesh and fancy diverters. Guess who still ended up ankle-deep in water at midnight during a freak downpour? Yep, yours truly. Plastic screens can be decent, but I've seen them warp badly in direct sun. Just keep an eye on them if you go that route...

Definitely agree on plastic screens warping - seen it happen a few times myself. If you're aiming for reliability, here's what I'd do: start with a solid overflow plan first (think oversized pipes or a secondary outlet). Then, pick your mesh carefully - stainless can be great, but it still needs regular checks for debris build-up. And don't forget about maintenance access; nothing worse than wrestling with clogged screens during heavy rain... been there, done that, got soaked.

Good points about the overflow setup - learned that lesson the hard way myself. Curious though, have you found stainless mesh worth the extra cost? I tried it once, and while it held up better than plastic, debris still piled up pretty quick. Ended up switching to aluminum mesh with slightly bigger holes... easier to clean and still kept most junk out. Anyone else had luck with aluminum or is stainless really the way to go long-term?

I've actually bounced between stainless and aluminum myself - honestly, I think aluminum hits that sweet spot. Stainless mesh is sturdy, sure, but it's pricey and debris still cakes on pretty quick. Aluminum with slightly bigger holes works well enough, and cleaning it is way less of a chore. Plus, if you accidentally bend it during maintenance (speaking from experience here...), it's easy to reshape. Long-term, aluminum's been solid for me - good balance between cost, durability, and convenience.

I've mostly stuck with stainless myself, but you're making aluminum sound pretty tempting. How's it holding up against corrosion long-term? I've seen aluminum get a bit iffy over time, especially in wetter climates...but maybe I'm just overthinking it.

I've had aluminum gutters on my rain harvesting setup for about five years now, and honestly, they've held up better than I expected. I'm in the Pacific Northwest, so it doesn't get much wetter than here... Initially, I was worried because I've seen aluminum patio furniture turn pretty gnarly after a few seasons. But with gutters, as long as they're properly coated and you keep debris from sitting in them too long, corrosion hasn't been much of an issue for me. Curious though - are you planning to filter your harvested water for drinking, or just gardening?

I've been using aluminum gutters for rain harvesting too, going on about three years now. I'm in Florida, so humidity and heavy rains are pretty common here as well. Honestly, I haven't had any corrosion issues either, but I do make a point to clear out leaves and debris regularly - learned that lesson the hard way after a clog caused overflow and soaked my porch furniture. As for filtering, I just use mine for gardening and washing stuff outside... drinking water seems like a whole other level of filtration hassle I'm not ready for yet.

"drinking water seems like a whole other level of filtration hassle I'm not ready for yet."

I totally relate to this point. I've been running a basic rain harvesting setup for about two years now, mainly for watering my vegetable garden and rinsing off patio furniture. Initially, I thought I'd eventually upgrade to drinking water filtration, but after researching the costs and maintenance involved, I decided it wasn't practical for my budget or time. One thing I've found helpful is installing simple mesh screens at the gutter downspouts - it significantly reduces debris buildup and prevents those annoying overflow issues you mentioned. Also, since you're in Florida, have you had any trouble with algae growth in your storage tanks? I had some minor issues last summer (I'm in Georgia), but adding a dark cover over my barrels really helped keep sunlight out and algae under control.

I've been thinking about setting up a rainwater system too, but honestly, the idea of drinking harvested rainwater still makes me a little uneasy. Not just because of filtration hassle, but also because I'm skeptical about the consistency of water quality throughout the year. Your suggestion about mesh screens at the downspouts is solid - I installed something similar last spring and haven't had any major clogs since.

As for algae, I did notice some buildup after a particularly sunny stretch last summer. My neighbor recommended painting the tanks black or dark green to block sunlight, and it actually worked surprisingly well. Another thing I've found useful is positioning tanks in shaded areas whenever possible. It's not always practical depending on your yard layout, but it definitely helps slow algae growth.

Maybe someday I'll reconsider the filtration thing, but for now I'm happy just using it for gardening and outdoor chores...baby steps, right?

You're definitely on the right track with the tank shading thing - I did something similar and noticed a big difference in algae growth. As for drinking harvested rainwater...yeah, I get your hesitation. I mean, filtration setups can be pretty intimidating (and pricey). But honestly, using it just for outdoor stuff is already a huge step forward. Maybe down the line you'll feel differently, but even if not, every little bit counts toward sustainability, right?

I wouldn't treat a mesh, charcoal and ceramic combination as proof that rainwater is safe to drink. Roof runoff can carry germs and chemicals even when it looks and tastes fine. Before using it for drinking or cooking, ask your health department about testing and treatment for the actual collection system and water quality. Keep harvested rainwater from entering pipes that carry safe drinking water, too.

The treatment needs to match what's in the water. Boiling can kill germs, but it won't remove harmful chemicals; UV also addresses microbes rather than chemical contamination. A DIY filter followed by either isn't automatically a safe drinking-water system. I'd get the water assessed before choosing the treatment stages.

That distinction matters, especially if anyone will be drinking it. A normal taste or clear appearance won't verify treatment performance, and a UV unit still has installation and maintenance requirements. Until the collection and treatment system has been properly assessed, use a known safe supply for drinking and cooking.

If UV is part of the design, choose and maintain it for the specified water quality and flow, including any required pre-filtration. It still won't remove chemical contaminants. For budgeting, include testing and ongoing treatment maintenance as well as the tank; garden watering and drinking-water supply have different requirements.

Good points on the UV sterilizer, definitely seems worth the investment. I'm still crunching numbers on my rain harvesting setup - anyone have insights on balancing cost vs. efficiency for storage tank size? Don't wanna overspend unnecessarily...

Definitely smart to crunch numbers first - I learned that the hard way. When I set mine up, I went big thinking "more is better," but turns out I rarely used more than half the tank capacity. Ended up just wasting money and yard space. I'd suggest tracking your actual water usage for a bit first, then sizing accordingly. Better to start smaller and expand later if needed...saves cash and headaches.
