I wrapped each connection in place with corrugated tape to make sure everything stays water-tight. I have the Y going into the downspout for a clean-out, so I can cap it but still be able to stick a garden hose if I need to flush it out. To connect the sump pump, cut off the corrugated to the length needed, and attach the coupling.
From there, I was able to tighten it up and secure everything in place. Moving to the other end, connect the elbow and install the pop-up emitter. Be sure to align it just below the grade so you can mow your yard easily. Backfill in some dirt and compact it down. Happy with what you see? While the time and effort is high, so is the payoff. Would you take on this project? If you already have, let us know how it went in the comments below or what you would have done differently.
This allows proper water runoff. Then they carry that water to the underground drainage system. Runoff also will help prevent the build-up of moss or mildew on your roof or where the roof meets the walls of a house. A downspout is made out of any of several different metals, including galvanized steel, stainless steel, aluminum, PVC, plastic, and copper.
Keep in mind, a portion of the downspout goes underground. It should be sturdy, long-lasting, and durable. Typically, the underground drains are made of clay, PVC a plastic material that is durable , or a perforated plastic pipe. Installing an underground downspout drain yourself is one way to save money. Thank you so much for this very informative article.
Our neighbor just installed a drain that never sees daylight and it ends at our property line. Should hey have gotten permits for this? The drain is by the corner by our garage and thankfully a long way from our basement but that area always floods anyways during heavy rain. Do you have any suggestions? Loren Don't use perforated pipe for roof drains buried near the building; doing so invites a water entry problem.
I know one inch per ten feet grade drop, not a problem. My question is, do I use solid PVC along the house or perforated? Seems to me I need solid to get the rain water away from the side of the house sitting on pier blocks. How to proceed? Those ties being metal I can see the rust marks which makes them easy to spot. They are above grade and also under the exterior parging which is strong and intact.
Perhaps capillary action below the parging, not sure. At first I assumed effervescence was coming only from moisture from winter muck from the vehicles, but then on day when the garage floor and wall were dry, but was raining heavily outside I noticed the moisture spots at the tie points.
I will double ensure all grading is proper away from the house and ensure moisture can get past the landscaping plastic. Lisa The answer to who can do buried downspout repairs depends on how deep the lines are buried and how much damage there is. A handyman can dig a small trench and replace a small section of buried downspout line - an d by the way check to be sure the line drains properly away from the building and to daylight. But if the line is more than a foot or so deep or there is extensive damage you probably need an excavation contractor with a small backhoe.
What type of company do I call to find and fix where my underground downspout feed has been crushed by heavy equipment? Lynne In my experience all such water absorption systems eventually become clogged and stopped working.
Just how much life you will get from your system depends on several basic variables such as the volume of water in flow, the soil percolation rate, and of course the overall size of the trench that's being constructed as well as its constituents.
If it's physically possible the very best solution is not to bury roof drainage but to conduct it to Daylight away from the building in a location where it will not drain back toward the building.
I am running my downspouts into a perf pipe in a dispersal trench, with rock surrounding the pipe. Probably not, Dan if it's just handling roof-runoff; but check with your local building department: they're the final legal authority where you live.
