Underground downspout repair to fix, drain water for dry basement and driveway



hi I'm Blair Gilbert here for mr. hardware and Gilbert's pro hardware in st. Clair Shores we are here to talk about underground downspout fail you see that this pipe is full of water here's a situation where this unit this kind of complex had a downspout was dumping on the ground and the water would puddle in this concrete you sell this concrete is all sagged big deep cracks and so it's settled down here it's settled because all the water that flooded in this corner went down to the drain tile went to the sump pump and each year so many pounds of soil went with all that water in an under – concrete hence the concrete has fallen in a mediocre attempt of repairing this the Association has hired some mediocre landscapers they've taken the downspout they buried a four-inch PVC out in the lawn but what they neglected to do was a direct connect to the downspout where there's trees in this area all the crumb that comes off the roof goes down this pipe travels underground to where these folks put in a popper but what has happened is this homeowner has is attempting to free although this is all the crumb that comes off the rough maple leaves and I already played this loose once this is a pop-up it looks like a great idea it's not so great this is a pretty poor end of semi expensive evacuation system for the water because it's all done by gravity this has to be lower then that pipe for the water to come out that's natural it's easy but what we like to do is we like to put a tee here the tee then can be in the ground at any particular height so that when the water drains from the house to the tee the pipe is always in a downhill angle at the bottom of the tea we put a post hall full of pea stone that allows the system to continually drain itself even if it takes a couple days so hold water for very long so when this flows water out in the ground and a strainer then the system will drain again in the winter time January when there's a freeze thaw sequence this won't freeze and break the pipe the other nice thing with the T is the strainer lifts off a little easier these lock in the strainer just slips right off you can put your hand in because some stuff still makes it to the strainer but this system is going to go bad very quickly once this pipe if no one maintains this this pipe fills up with all these leaves in this crumb it's going to right and impact the pipe water's going over floor it the house more water in the ground more cement say so this is really a poor design it's too bad it looks good at on the Shelf of the store but in reality our goal is to get water away from the house filter we're taking a look at what happened to this pop up in this elbow and we're going to show you how nice we can change this into a tea I'm going to take a look in here when I see that this pipe is full of water did it move okay a mood didn't if you didn't do it so here see how much water is in here and we're going to do is win dig a post all down here so I'd underneath this fitting I taken out this elbow we're going to put a French strain below this we're going to take what was a good system and we're making into a great system but it we couldn't put any closer to that sprinkler line huh we have about a two foot deep hole at the end of this underground downspout what we're going to do in lieu of that pop up this ninety does pop up ninety they put a little slot in the bottom to drain it it's not enough it's so easily clogged with a couple of leaves and a little bit of dirt you saw this this was holding water to what we do is we put in a tea upside down when you put the tea upside down we're going to take and bring a piece of PVC up to the top of the earth we're going to put a green strainer in it so it blends in with the grass I'm going to fill this with pea stone what that's going to do for us that P stones going to act like a French drain so those water builds up in here now we've created a conductor so it's water can go down in the P stone and it can wick into the earth and this will auto drain so this won't hold water in the winter time when we have a freeze thaw sequence where it's warm in a January and snow melts off the roof and comes down here we want it to be able to dissipate in the ground and that keep our system freezing make sure you cut up the part where I'm struggling there we're going to ship this thing over the side a little bit okay we finished in the tea we have our two foot deep post hole down below now here is what's going to make our pipe auto drain in the winter time and a lot of times I'll pour it in right through the center of the tea so here we have it of course we had to dodge a sprinkler line if you notice this going on by we put in our pea stone we got it right up to the bottom of the tea so now any excess water that doesn't come out the strainer out on the line will eventually go into the pea stone when it rains and all the rain water comes in here it's going to saturate this pea stone typically in just a couple of minutes during a rainstorm then the water is going to come out the top of this T because this location is lower than where the water is being inlet down at the end and so what will happen is what will come out on the line here for a long time and one it's easy to clean it and put my hand in here I can reach down if I get leaves or accumulation of credits easy to clean instead of this being holding water this will eventually drain in this ground this stone will help accumulate all of our excess water and drain it in the earth so our system will go dry within hours typically after every rainfall this will make this system last a lot longer and be much more maintenance-free than using an elbow like this that never drains this strainer needs to fit inside a piece of pipe then inside the tea for taking your topsoil and throw it in there and take a garden hose on it soak in here's our Devon spout inlet into the system direct connected typical what we want to do is we're going to cut the PVC we're going to put a strainer in here so now when leaves come off the roof they're going to splash away and only water is going to go out to our system keep our system much more maintenance-free as I said before I've got a few of these or 15 years old and I just have to keep cleaning the kaabah crumb out of them about every four or five years if I don't have this I better clean the crumb out every year so it's just a better way to have a little filter this is SDS 35 pipe which is a little thicker ID than the thin wall stuff today normally use media to rest there we go good okay so now the second thing we want to achieve is we do not want this pipe right up against this grade or the leaves will accumulate and get trapped so I like to cut an angle on the downspout so as it lays up against the debris filter the leaves have enough room to evacuate and drain away so we're now we're going to shorten up the downspout now as leaves and crumb along with all the water come down the downspout leaves have plenty of room to evacuate the water ninety-five percent of the water will go down our drain and go out in one no more water at the basement this is the way to keep your basement dry just make sure when the water comes out out on the lawn your lawn is pitching downhill that water can't roll back to the house and cause more wet basement so it's all about water management and having grade 2 water drains away so when it rains your basement stays dry

    Mr. Hardware, Not to sound like a know it all but someone has a comment about the pea gravel itself plugging up, this person is absolutely right I know without question pea gravel does plug up very easily just think about how small the holes are through the pea gravel, it does not take much to plug every hole. Always use Drain rock (clean River rock) is absolutely the best the space is huge between each stone compared to pea gravel and of course the special fabric that is made for this exact project will make the drain last indefinitely because the fabric can only get a thin layer of dirt on it whereas the Pea gravel will build a layer of dirt as thick as the Pea gravel is deep, stopping the seeping action completely.

    I've probably watched at least 100 videos on french drains, storm drains and downspouts and not one video has mentioned the end of the run of pipe and what to do if its not cutting through a curb. You seem to really know what you are talking about. Great video. Thanks

    Would a 3" PVC pipe be sufficient to do its job?

    Thanks for the informative video. Since I'm unable to do this task myself, do you recommend I hire someone who fixes gutters or someone who can fix the drain? Mine is currently clogged. and requires immediate attention.

    You need to use a soil separator fabric and then fill with stone. Otherwise, the soil will eventually fill in between all the stone and it'll plug up.

    I have the same system (pop-up with elbow that is forever full of water). Any reason I can't just install the gravel drain but re-use the pop-up instead of buying a new strainer cover? Seems to me the pop-up is just a different but still acceptable way to allow water leave the pipe. Am I wrong? Thanks.

    I am thinking about putting this system in along the side of my cement driveway. Do you think this would be ok 3 feet from the driveway? I actually could just run the water from downspout down the driveway but the look is not great.

    Oops. I did it the wrong way, but I no longer own the home. The new homeowner has to figure it out, but since it’s in California and it hardly ever rains, he might never find out.

    Very informative video. I have been using the same popup outlet for years to discharge my sump pump water out but it wasn't efficient and failed after over time. I recently installed a french drain across lowest points in backyard and extended my sump pump PVC line with a solid corrugated pipe into a catch basin connected to french drain which would eventually discharge water to a storm drain. I did the same thing for downspouts. Your solution acts like a small catch basin which is sufficient for water coming from a downspout. But installing a larger catch basin with french drain that has access to a storm drain or street outlet would be a permanent solution for all of downspouts.

    Why do you need a piece of pipe between the strainer and tee?

    Lately I have been lining the post holes or dry-wells with landscape fabric to reduce soil infiltration into the stone bed.

    Thank you for such a great video. I’m in the process of making one of these drains but also had a question on the “T” direction. I saw your earlier clarification on wanting the water to go up but am still slightly confused. In either position up or down won’t the hole with stone fill first? While testing it with my garden hose I noticed when I had it positioned up the lip trapping a small residual amount of water in the pipe even when I stopped the flow. This scared me being in Vermont thinking about freezing and re-freezing, I could see that creating an ice dam eventually. With the T flipped down the pipe drained dry every time. Again, won’t the hole fill first no matter the direction of the T? I’ve also got some serious clay in the area of the drain so I’ve gone about 5’ down and 3’ across. It’s a pretty big hole…. any other thoughts on an area with deep freezes and poorly draining soil?

    Mr Hardware…I have a 100' run starting at 6" deep ending at 24" deep. In this run I have 3 downspouts running into 4" corrugated solid. My question is at the end of the run whether I choose a "T" or a pop up? Will the water rise to the top and flow out? Im worried about the distance and depth of the end run. The closet downspout to the end of the run is about 15 feet away.
    I live in Canada with alot of clay soil. I tried just dumping the run into the ground but it wont drain in to the earth in a decent time. Were talking days if at all. This is why im thinking of a solid elbow pvc and up the 24" to the ground level. Before we dug this trench i did test our natural grade and the water ran well. should i be looking at filling in and starting over with a much more gentle slope? If so…how deep should the end of the run be to allow the water flow up through the vertical rise and out at the ground level?
    Any help would be appreciated..Thanks..Jim

    Is there any concern with the pvc pipe freezing? I've been looking into both pvc and the n12 corrugated dual or triple wall corrugated pipe for when i run my pipes underground in my yard. I live in wisconsin
