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

Been thinking about putting together a rain harvesting setup at my place - nothing fancy, just something practical to water the garden and maybe cut down on the water bill a bit. I've seen a bunch of DIY videos, but honestly, I'm a bit overwhelmed by all the bits and pieces involved. Like, do I really need a fancy filter or can I get away with something simpler? And what about tanks - plastic vs metal, pros and cons?

Also, gutters and downspouts...are there specific types that work better for this kind of thing? I mean, I don't wanna spend a fortune, but I also don't wanna end up with something that's gonna leak or rust out in a year, you know?

If anyone's done this before, it'd be great to hear what worked well for you or if there's anything you'd avoid next time around.

Honestly, you don't need to go crazy with the filters - unless you're planning to drink it, a simple mesh screen to keep leaves and bugs out usually does the trick. As for tanks, plastic is cheaper and won't rust, but metal lasts longer if you get a good quality one. I went plastic myself (budget reasons), and it's held up fine so far. Gutters-wise, aluminum is your friend - affordable, lightweight, and doesn't rust easily. Just make sure they're installed properly or you'll be chasing leaks forever...trust me on that one.

Totally agree on aluminum gutters - seen way too many DIY setups leak because of sloppy installs. One thing I'd add: consider a simple first-flush diverter. Keeps the initial dirty runoff out, saves you hassle cleaning the tank later...worth the small extra effort imo.

Good call on the diverter - I put one in after my first tank turned into a mosquito breeding ground (lesson learned the hard way...). But honestly, aluminum gutters aren't always the villain. I've seen some PVC setups leak just as badly if they're not sealed right. The key is taking your time with the joints and using a good quality sealant. Trust me, nothing ruins your weekend faster than chasing down mystery leaks in the rain.

Yeah, sealing those joints properly is definitely key. I went with PVC gutters myself - cheaper and easier to handle solo - but had to redo a couple sections after the first heavy rain. Also, about filters: I skipped the fancy ones and just used a simple mesh screen. Works fine for garden watering, but if you're thinking of anything more sensitive (like veggies), you might wanna step it up a notch.

Yeah, sealing joints properly can save a ton of headache later - I've seen plenty of setups where folks underestimate that step and end up with leaks everywhere. Mesh screens are usually fine for basic watering, but have you thought about maybe adding a simple sediment filter downstream? It's not fancy or expensive, but it helps keep finer debris out of drip irrigation lines and sprinklers. Might save you some cleaning time down the road...

Good call on the sediment filter - those little bits of grit can really clog things up over time. Learned that the hard way after spending a weekend unclogging drip emitters... not fun. Curious though, has anyone here tried one of those first flush diverters? I've heard mixed reviews - some swear by them, others say they're more trouble than they're worth. Wondering if it's worth the hassle for a smaller home setup.

Yeah, sediment filters are a must - saved myself a ton of headaches once I finally installed one. I've messed around with a first flush diverter too; they're decent but can be finicky if not cleaned regularly. Might be overkill for smaller setups though...depends how much maintenance you're up for.

Installed a first flush diverter myself last year, and yeah, they're handy but definitely need regular attention. Forgot to clean mine once after a heavy storm...ended up with a clogged mess. Sediment filter alone might be enough if you're aiming for low-maintenance.

Good call mentioning the maintenance aspect - people often underestimate how quickly these setups can clog, especially after storms. I've seen a few setups where folks relied solely on sediment filters, and honestly, they seemed to hold up pretty well with minimal fuss. Still, I'd personally lean towards keeping the diverter in place. A bit more upkeep, sure, but it adds an extra layer of protection against contaminants. Maybe just set a regular reminder on your phone to avoid another messy surprise...

I've gotta admit, sediment filters alone can work surprisingly well, but I'd still be cautious about ditching the diverter altogether. Had a neighbor who went filter-only and seemed fine for months - until we got hit with a nasty storm. Ended up with all sorts of debris and gunk clogging the system, took him ages to clean it out. I'd suggest keeping both in place, at least initially, then maybe experiment by temporarily bypassing the diverter during calmer seasons. See how it goes from there...

"Had a neighbor who went filter-only and seemed fine for months - until we got hit with a nasty storm."

Yeah, that's exactly what I'm worried about. I just set up my rain harvesting system a couple months ago, and while the sediment filter alone has been doing a pretty decent job so far, I wouldn't trust it completely during heavy weather. I mean, filters are great for catching smaller particles, but when you get hit with leaves, twigs, or even bigger debris from a storm, things can get messy real quick.

Personally, I've kept my diverter in place as a backup. It's not that much extra hassle, and it gives me peace of mind knowing there's an extra layer of protection. Maybe down the road I'll experiment with bypassing it temporarily, like you suggested, but for now I'm playing it safe. Cleaning out clogged pipes after a storm doesn't sound like my idea of a good weekend...

Haha, yeah, learned that lesson the hard way myself. Have you thought about adding a leaf guard or mesh screen on top of your gutters? Filters alone won't keep out bigger stuff, especially during storms. I was skeptical at first, but it really cut down on maintenance headaches. Might be worth looking into if you're worried about debris buildup...

Good call on the mesh screens - definitely helps cut down on the gunk. A couple more things to keep in mind from my own setup:

- Make sure your downspouts have a decent angle and aren't too narrow... learned that one after dealing with standing water post-storm.
- Consider adding a first-flush diverter if you're harvesting rainwater. It dumps the initial dirty runoff, so you end up with cleaner water in your storage tank.
- And yeah, cleaning pipes is never fun - especially when you're elbow-deep in soggy leaves. Been there, done that, no thanks.

"Consider adding a first-flush diverter if you're harvesting rainwater. It dumps the initial dirty runoff, so you end up with cleaner water in your storage tank."

Totally agree on this. Installed one last summer and the difference was noticeable right away - way less sediment buildup. Another small tip: if your tank isn't opaque, give it some shade or wrap it up somehow. Sunlight hitting stored water = algae city. Learned that one the hard way...

Good call on shading the tank - I had an algae bloom once and it was nasty to clean out. About the first-flush diverter though, is it really necessary if you have good gutter guards? I mean, wouldn't decent leaf screens already keep most of the junk out? Genuinely curious, because I'm planning my setup now and trying not to overcomplicate things...

Good gutter guards definitely help, but first-flush diverters catch finer stuff like pollen, dust, and bird droppings that screens might miss. I’ve seen setups without diverters do fine, though the water quality usually isn't as good. Depends how clean you need the water - are you using it just for garden irrigation or planning on household use too?

I agree, first-flush diverters really do make a noticeable difference, especially if you're aiming for household use. I've managed a few rental properties with rain harvesting setups, and tenants definitely notice the water quality when diverters are installed. Gutter guards alone are decent enough for watering gardens or washing cars, but if you're planning on using the water indoors - like laundry or toilets - you'll want that extra filtration step.

One thing to consider is maintenance. Diverters need regular checking and cleaning, otherwise they clog up and become less effective over time. I've had tenants neglect them, and trust me, it's not fun dealing with backed-up systems later on. So factor in how hands-on you're willing to be with upkeep.

Also, think about your roof material. Metal roofs generally produce cleaner runoff compared to asphalt shingles, which can shed granules and chemicals into your water supply. If you've got shingles, I'd definitely recommend the diverter route... just my two cents from experience.

Good points here. I'm curious though, has anyone noticed a big difference in the amount of debris collected by diverters depending on surrounding trees? At my parents' place, they have tons of pine trees nearby, and even with gutter guards, needles still seem to find their way in. Wondering if certain diverter brands or setups handle that better... would hate to install something only to realize it's not suited for our specific situation.

Yeah, pine needles are notoriously tricky. My neighbor has a similar issue - tons of pine trees around his property - and he tried a few different setups before settling on something that worked decently. He ended up going with a diverter that has a larger mesh size specifically designed for needles, combined with a first flush system. The bigger mesh lets the needles slide off easier, and the first flush catches most of the smaller debris that sneaks through.

From what I've seen, brands like Leaf Eater or Rain Harvesting seem to have decent needle-specific options. But honestly, no setup is 100% foolproof with pines. You might still need to do occasional maintenance, but it should be way less frequent. Definitely worth looking into those needle-specific meshes before committing to anything expensive. Good luck!
