Our patio cover has a pair of scuppers to drain water running down from the room. Sort of like this:…

1poorlady puts barrels under them to catch water, which works moderately well. But if the wind is blowing, the streams can go almost anywhere. She is wanting to attach something that will restrict the flow and direct it to her barrels.

I think she’s envisioning something we could remove whenever we like. I suspect the force of water would prevent such a setup, but I could be wrong. Maybe there are flexible sleeves that could do the job? Not finding anything, yet.

We thought the scuppers were cool and elegant. But a downspout may have been more utilitarian, especially as she like to catch the (rare) rainwater for her plants and garden.

Any ideas?


What I’ve seen on various rentals up the coast id that instead of downspouts, they used chain, more ornamental than for strength, but the water sticks to it, comes down to a rock filled collector at the bottom, but could easily be a barrel…

An example…(Searched for ‘chain drain’)…

Maybe find sources there or maybe local…

The illustration at your link shows the water flowing with quite a bit of force and a substantial arc. Is that what you get? How much does it vary, without taking the wind into account?

My first thought was rain chains instead of downspouts, but you would have to take the momentum out of the water first. A simple chain might not help much with the wind, but a version that is like a succession of buckets might give you victory over the wind. One at the link is rather large.……

That still leaves you with the challenge of turning the water direction to downward. I suspect that will require some innovation, something not off-the-shelf. Imagine the first cup of one of those cup-style chains almost swallowing the end of the scupper, perhaps with part of one side cut away in an arc to fit it. Supporting the weight would the the next challenge.

They are, but rain chains can be too!

What’s the shape and diameter of a scupper?

Inside and outside diameter. Do your scuppers have the approximate shape of those in the link’s illustration?

They’re more rectangular. I’d guess about a 6"x8" opening. I like that chain idea. That could be really attractive AND functional.


I was thinking they were round, like the ones in your link… in which case there are scads of 90 degree plastic or rubber adapters.

But rectangular is a hawse of a different color.

Try this:

Home Depot has a pretty good selection on-line. We thought about them years ago when we were having gutters installed. Ended up not getting them, not because we didn't like them. Rather, we just don't get that much rain. For us, our gutters or more like crown molding for the outside of the house.


We don’t get that much rain, either. About 6" a year. Maybe 8". But when it does rain, it RAINS. We can get 1/3 of our annual rainfall in one day. The water gushes from the scuppers. As long as there is no wind, it fills her buckets pretty quickly. But there often is wind, and the water streams blow every which way.

She’s thinking about the chain idea.

We have no gutters (most Phoenix homes don’t have them), and it would destroy the look of the house if we installed some. We’d probably have to have the facia removed so that the gutters wouldn’t allow water to channel under the roof tiles and underlayment. I’d want a pro to consult for that.

Rainchain works fine for a straight-down water from a typical rain but not for water pouring out at an angle, esp. with lotta wind. You prob need proper downspouts for that. Could get some nice copper ones that would complement what you have.

I’ll try to post a photo somewhere, and link it. Though I believe I saw you on the Discord, so I could post directly there.

Copper sounds lovely. Just trying to visualize how that would work. The scuppers protrude out from the parapet, so attachment might be challenging. The chains seemed easier to do, but sometimes the water does gush, in which case they may not be effective?

Take a good look at this bucket style rain chain:…

Now imagine that the top bucket has one side cut away to make room for the end of the scupper, and is fastened in such a way that the gushing flow from the scupper collides with the far inner side of the top bucket. Yes, there is still the issue of attaching it to the scupper but I double you will find an off-the-shelf solution. That needs to be improvised.

By the variety and artistry of the bucket type rain chains I suspect they are made by craftsmen as opposed to being imported from the far east factories. Check out the blog at that site. Send photos of your scuppers to them and maybe they will devise a fix for you and make a blog post about it.
