Help with self regulating rain barrel
I have an aluminum downspout going from the roof of my two story row house down into the ground. I don't know where it goes after that, but I suspect a cistern under the yard of my house circa 1929. At any rate, I've never had any drainage problems with it. I'd like to install a rain barrel, the kind that is self regulating, meaning when the water reaches a certain level in the rainbarrel, it diverts back into the downspout. I'm not home enough open it up and close it, and besides, the water doesn't drain onto the ground so I have to divert it from the pipe and back again. Has anyone had any experience with this type of system. Does it work like it's supposed to? If things back up I could have a real problem on my hands. Any system better than another? The one I'm eyeing is from the Gardeners Supply Catalog. I don't use that much water in my tiny yard but I'd like to make use of the rainwater. Right now I'm thinking, "If it aint broke, don't fix it."
You can sort of see the rainpipe in the back of this picutre against the house. Like I said, it disappears into the ground and my neighbor told me there were cisterns buried under the yard.
