Underground Drainage System - Downspouts 101

with all the different pipes to choose from for a homeowner it could be quite overwhelming I'm hoping that clarify why we use the pipes we use how we use them and when we use them there's three that I use exclusively and then there's several that I won't go near and we'll touch on it all the number one pipe for me is a single wall corrugated pipe the reason why this pipe ranks number one with me is because I can run it in one piece it's not a pipe that comes in sections it's not a pipe that has to be glued together it's one from the adapter that goes on the end of the gutter downspout all away doesn't matter if it's 30 40 50 60 feet I don't care as long as it's you know installed correctly you can run into a pop-up and you can run it to a I like these six inch catch basins too so those are the two that we use why is it so important that it's one piece to me with all the trees and all the shrubs in residential landscapes roots roots are what takes out an underground drainage system roots are the kryptonite to an underground drainage system so your argument can be well we're going to glue the pipe together we're going to glue all these sections together here's the problem we face in the north in the Sun Belt Region you guys don't deal with this but we deal with this we have to get this pipe down 42 inches or deeper for it not to see the effects of frost and freeze and thaw that's impossible in most cases that's not realistic running an underground drainage system in your backyard you're not going to be beneath the frost and here in Michigan you're gonna see that pipe go through all types of stresses hydraulics we can get geeky and get you know go to the math and figure it out but this pipe is virtually indestructible it's very flexible so as the freeze and thaw cycles occur it can move as one and come spring it returns right back to the original slope at which it was installed now this this pipe has been given a bad rap and I want to go over that real quick the problem is when it's installed wrong it will collect the breeze and I'll explain why this here has been circulating for a while and it's the most misunderstood part about the drainage community it's as a homeowner you're you're left to think what do i what do I believe well I'm just gonna give it to you straight it's as simple as this when the water comes out of the trough and it drops into this downspout that water is accelerating all the way into the point to where it enters the underground drainage system at that point you want to maintain slope on this pipe so that you can keep up your acceleration you want to keep up your velocity you're never gonna get it back if you run this pipe flat as it loses velocity you're not getting it back it's lost so the key is how its installed it has to be installed on a slope if it's installed on a slope it'll mean gain velocity which flushes out leaves and tree seeds and should go gravel now how did it get a bad rap well it's pretty easy to leave a belly in this pipe now you'll hear me say that in videos I have in previous videos and I'm sure I'll continue to use that term in the future when you take it under a sidewalk and then you bring it back up and put a pop-up admit on it that's a belly now when the water comes down it hits a bunch of water that's just laying in the belly so what ends up happening is you lose all that velocity sure eventually the right of weight does prevail so water is eight pounds per gallon say you got two gallons and there you get sixteen pounds worth of water as the gutter downspout loads up during a rain the rate of weight wins it'll push through you won't even know there's a problem but in the end you lost all your velocity that's what carries out the debris in this pipe so the Installer screws up the pipe gets a bad rap for more in 30 years I've been using this pipe and I love it now the pipes with the glue joints the glue welds they move in the freeze and thaw cycle and it breaks the glue weld so when you put two pipes together and you have these broken glue welds well trees root systems even on shrubs that's a the kryptonite of underground drainage systems you're going to plug that system with roots now tree roots are they start off finer than the human hair so that's how they get into this system and then they grow from there and then they they break it down it ends up being a mess ends up having to be redone again the PVC schedule for tea has a great crush rating I do use it on industrial jobs where it's spec 10 we're going to go over that before we end this video but I just want everyone to understand and be clear that because we can run the single wall corrugated because it comes rolled up and we got these 150 foot rolls and we could without any connections we could run this as far as we need to as long as we can maintain slope I'm confident that it's never going to collect debris and it's never gonna plug now what do I do if we end up having to go flat we just don't have the slope I know we're gonna lose the velocity I know we're gonna lose the ability to flush this claim well that's when I'll step up to the dual wall and you've seen that in previous videos as well I'll start featuring it more but it's smooth on the inside it's dual wall so you got your corrugated exterior smooth on the inside so when their velocity goes down it'll still carry the debris very easily it's a little more money but what I like is their 20 foot lengths instead of 10 foot lengths and that's what the PVC pipes are is ten foot lengths not only is it 20 foot lengths so I have less connections but look at the flexibility I got it's not it's not like the single wall the single wall is crazy flexible but it's pretty good I can influence this pipe to go up and down hills you know when you're doing walkout basements for example and you're running a downspout and you have to go down towards the walkout basement area and take it deep into the back of the yard this pipe will actually make that without connections so you do have the 20 foot lengths so let me get to that what we do is wherever there's a tree or shrub or landscape we have connectors and we actually have a tape an agricultural tape for this and we'll wrap it the tape last 400 years this pipe by the way in truth I've dug up this pipe that and it looks brand-new when it's 40 years old because I've dug up some old systems that weren't run they didn't run them correctly so they had to be redone but the pipe looks brand-new it's it's truly amazing they're telling me that this pipe is going to last two to five hundred years before it breaks down I believe it I believe it I see it never seen deterioration in this pipe in any way not from the Sun you know when it's exposed and it's out of the ground and you know that brings me to a pipe that is constantly being misused and that's triple law now what triple wall is it's a corrugated pipe and they do this like a laminate white exterior and then it's got a black smooth interior this is ideal for septic fields because they don't see daylight it doesn't have any UV protection so just look at this it's a mess so don't use that it's tempting because I see I see people walking out a Home Depot with it all the time to do their downspouts plus I hate these these adapters that go on the downspout see how its squared you should see during rain how that sprays up it's unbelievable like a geyser so you're losing your your velocity to carry the water water splashing out and I've seen guys on videos use silicone why why look at how nice these are it's ramped it's ramped it don't spray out you don't have this huge spray and you don't need to silicone it so for me corrugated pipe is my go-to I'll always go to the single wall first and then if I find a need for the dual wall because I need a smooth interior I'm gonna lose my velocity the water is gonna slow down on me I don't feel like we're gonna carry any debris very well I'll run this smooth wall you know if I get a flat spot in my run I'll go to this dual wall and then I'll put it to this little 6-inch NDS catch basin so the homeowner can maintain the system by cleaning it out as needed now do stay away from this as a homeowner because I know it's so tempting you see this in a store and you're thinking oh this is great it fits in the back of my car seat and I could just extend it let's see here there you go boy that's pretty impressive pretty neat and it'll actually you can pull it to it to the point where it's ten feet long but that is the end result it's garbage stay away from it I also I want to touch base on this this is the area that my systems if they're going to not work it's because they they got plugged up up in the gutter trough so before the water ever made it to the downspout you end up with a bunch of leaves just plugging this hole so that now the gutter trough loads up with water and it gets so heavy that it pulls it away from the fascia board that's how gutters end up all screwed up and then you end up with this cascading effect and all the water runs over the gutter and just floods out the landscapes now you got water coming in the basement and you're blaming what the underground drainage system is not working in a case like this what you need is leaf guards you need to put leaf guards on none of us need to be going up and down a ladder cleaning gutters out all the time so I really recommend you definitely put leaf guards if you have a lot of large trees now they do make for the hard pipe a more centered adapter you know opposed to the one that's squared and sprays a mist and just makes a mess but the problem is you end up having to be too far off the wall of the house and then you got to have slope so you tilt your hard pipe that's why I like the corrugated plate but has all that flexibility that I showed that looks terrible it's off the house it just looks terrible now where does this the PVC schedule 40 belong right here commercial building there's no trees or shrubs this is ran under the parking lot even if the pipe moves in the winter and it breaks the glue welds there's no trees around it's just all asphalt or concrete here's another one you know did it a clean out nice neat job I like it anyways go under the asphalt parking lot there's no trees there's no shrubs so that's where the schedule 40 belongs here in the north you're not gonna beat a single wall corrugated pipe and again if you can't maintain slope just go to your dual wall and I know I featured the dual wall in in other videos if you haven't seen them yet then you know they're up and coming or watch the playlist until you get to it that's kind of the 101 of downspouts if you're looking for
