Gutter Down Spout's In Ground Drain Clogged - Need Help

9 Replies

Hey Gang -
I've got a problem that I hoped you could help me solve without calling RotoRooter. My in-ground drain from a gutter downspout is overflowing. The drain does not run to the street, so I'm guessin git is a french drain. That said, I am able to get a hose about 20 feet or so into the drain with no interruption, but jamming it around in there isn't doing anything to get this thing drained.

I bought a declogger that attaches to the end of the hose, but it doesn't seem to help in this.

Anyone have any ideas?


If your drain is made from a pvc material you can put in a plumbing line drain cleaner that breaks down organic material and see if that breaks it up.

Josh, you will need to get to the root of the problem! Any shrubs near the drain line? You can rent a power drain snake with a nasty looking chopper dealy on the end for roots. Check at Lowes. Bill

Hey Josh, I am with Tim on this one. Try some common drain cleaners, if that does not work, I would abondon the drain and run new corrugated out a good 5 or 10 feet from foundation. Never a fan of those types of drains that go nowhere and chances are it will happen again at some point. Just my humble opinion.

stick your hose or whatever in there and see how far it goes, then lay it on the ground above the pipe and you will see were the blockage is.
dig it up, cut the pipe in half, and get the junk out of there. if it is black corragated 4 inch pipe, then you can get a coupling for 3 dollars at home depot and then wrap some duct tape around it. if its DWV pipe or SDR just go get a 4'' coupling for 3 bucks and slap that baby on there, glue is preferred but not needed, there is no pressure.
if you are having trouble locating the blockage, try runnin the hose from the drain end of the line not from the gutter downspout end.
hope it works,

Thanks for the tips guys. I did the hose thing and figured out where the blockage exists -- around 20 feet in or so, but I'm in no mood to start digging up my yard. I think I'm going to try some root stuff to see if I can get it fixed without going in with an auger or shovels.

In the meanwhile, I'm using an above ground spout extension to deflect the water away from the building.

Thanks again.

they are never buried deep, and a hacksaw will cut it in 20 seconds, but good luck!

Steven - The ground here in Denver is a bit more solid than it is in Houston, AND a bit more frozen this time of year.

that could be your problem if the line is shallow it could be frozen. it could have damned up if you have a root problem at that area or a flat spot or back pitched. wait for warmer weather and dig up at the spot were the hose stopped. if it is that black perferated pipe do not use a root cutter in it, it can cut that stuff. if you find you have a root problem try a foaming root agent like rootx

Joshua, if the drain does not run to the street, 20 feet might be all there is of it.

It's buried. The water has to go somewhere. If the end doesn't open somewhere, the drain will fill with water and then that is all it will take.
