welcome to the Aero general service Channel I'm your host Corey bartolotti and today's video we're going to be talking about drainage pipes now there is a huge debate between which is better corrugated or PVC and I'm here to tell you that the application is what determines what material you want to use all right so the black corrugated pipe that everybody knows and that's the center of the debate this is the stuff that you get in the big box stores I'm here to tell you this pipe was originally designed to be an agriculture fields that is where this pipe excels at it excels in fields with crops in them the reason for that is because this pipe is meant to be buried a good four to five feet down and in any type of farm field all you have growing in that field is crops there is not big trees there's not big shrubs and landscaping plants where the roots are going to grow and find their way into this pipe it is only crops and those roots are not going to get deep enough to affect this pipe now this pipe is inexpensive and it is needed to be inexpensive because on these Farm Fields you're talking about running acres and Acres of this pipe so that's thousands and thousands of feet this pipe comes in huge rolls and they lay this pipe deep so that the crop Roots do not affect it now the reason they do this is in sections of the field if they're trying to increase their yield if that field has too much water and it's too saturated because of the water table the roots to the crops cannot grow because they become too saturated with water so this lowers the water table so that those roots can grow better and you have more crops and more of a yield now before plastic came on the scene Farm tiles such as this tiled this clay terracotta pipe this is what was used to drain fields and to lower the water table they would have tons of these pipes sectioned out one after the other and they would just butt them up right against each other and it would create a little seam and that's how the water would get into the Terracotta pipe and would travel through the pipe and out to the exit this that's how they used to do it was with Terracotta clay pipes just like this one that you see until they switched over to the plastic corrugated that would come in rules the reason why this pipe made it into residential use and is on Big Box store shelves is like anything else it's capitalism it's to increase the revenue so now the problem with that is this pipe is made out of recycled plastic it's a bunch of plastic that has been melted down reformed and pulled into a pipe and that's what you got right here that's why this stuff fails because in residential yard drainage you cannot bury this four to five feet down and drain the pipe out and drain the system it's not practical it just will not work and because of that it's buried shallow I mean we typically only go a foot to a foot and a half to two feet deep at Max to be able to drain these systems on Residential Properties so that's just not deep enough for this pipe to be practical and for it to function Roots tree roots shrub Roots it crushes they will find their way into this pipe at the seams of the joint we have seen it we ripped them out all the time now if you I live up north I understand that you have freezes and thaws and you cannot use PVC because it has to go below the frost line and you need a plastic that will expand and contract with those freezes and thaws so you need to use an HDPE plastic a high quality one at that this is not that what you want to use is something designed specifically for that the fdm the French drain Man pipe this is a virgin material it's a lot thicker than this one and this is made for residential use this is made to be buried a foot to two feet down not Crush and once it's tile taped up at the seams Roots shrub Roots tree roots are not getting in there so you have to remember all these different pipes that I have here are for different applications and there is no one pipe fits all situations it just it doesn't work like that so you have to use the right material for the application and for the job now if you live in a climate where you do not experience freezes and thaws in my opinion PVC is one of the best options you can use for yard drainage especially sdr35 if you watch our Channel you know that I'm a sucker for sdr35 this pipe you get the benefits of it being both rigid tough and not only that but it fits into the sewer thin walled fittings these fittings are more budget friendly than any type of schedule 40 fitting schedule 40 now the prices are ridiculous the fitting prices are ridiculous so to be able to stay within people's budgets using this is a lot easier to do that than if you were to use schedule 40. now don't get me wrong if a client wants schedule 40 and they have the budget to do that then absolutely let's go ahead and install it especially you know if they are in a climate that is acceptable for it such as Florida now if you live up north I would not recommend using PVC free yard drainage at all because you cannot get it below the frost line and effectively drain that pipe so if you live up north you want to use HDPE pipe that's a high density polyethylene pipe the fdm the French string man high octane pipe is the best on the market and that's what you want to go for if you live in a climate that experiences freezes and thaws the problem with PVC in any climate that freezes is because it is so rigid that is its demise it cannot it cannot expand contract when the freezes and thaws occur now you might say well if the system is built correctly and the pipe doesn't hold any water then it's there's nothing in there to freeze and thaw out so it should be fine you would think that is correct but the problem is the ground around it is also expanding and Contracting because of the groundwater and because of moisture in the ground so because the ground around it is expanding and Contracting that is going to put pressure on PVC it's going to put it on the joints particularly anywhere that a joint is solid welded together is going to be its biggest weakness and that is going to crack under those types of conditions so if you live in a Northern climate that freezes go with a high quality drainage pipe that is made out of hdp material now I personally like sdr35 because of the reasons that I already stated but if you want to go a little cheaper a little more budget friendly you can always use schedule 20 schedule 20 you know I can make the pipe out around with my hand a little bit by crushing it but once it's buried in the ground it's not bad if you're in a if you're in a climate that doesn't freeze it's it's going to hold up now is it going to hold up as long as sdr35 probably not now when it comes to schedule 40 schedule 40 it really doesn't belong in yard drainage it is very expensive but like I said earlier if you can afford it it's going to last you forever as long as you're in a climate that accepts it now if you live up north and you install schedule 40 thinking well it's 40 gauge it's super thick PVC it's not going to crack you're wrong you're gravely mistaken it's going to crack and your freezes and thaws especially at the joints it's no different than using str35 or schedule 20 when you're using it up North so I do not recommend using schedule 40 up north it is not a good idea all right so let's go ahead and talk about schedule 40 for a minute if you're a client and you're paying an installer to install schedule 40 PVC for you there are some things that you need to know about this pipe now looking at both of these pipes they both look identical right they both look like they're schedule 40. I'm here to tell you these pipes are not created equally in my hands right now this pipe that I'm holding this is true schedule 40. if you go ahead and you bring that camera in closer we I will show you the differences here if you look at the if you look at the imprints here schedule 40 PVC right now if we look at this one schedule 40 cellular core PVC what that means is this is not solid PVC right here this on the other hand is solid PVC so you're getting 40 gauge solid PVC here and on this one you're not even getting a 20 gauge and a 20 gauge with a cellular core it's even thinner than that so what this pipe is right here which is called which is also called schedule 40. because it is that it has the thickness of schedule 40 but the inside portion that is sandwiched between two pieces of PVC this is what they call Cellular core it is not solid PVC so let's go ahead and get a close-up right here so you guys can see you see how that PV that real thin layer of laminate PVC on the inside has chipping and you can slightly see the difference between that and the inner cellular core the outside is the same thing it's a very very almost paper thin PVC laminate outside the problem with cellular core is over time this can chip and crack away and eventually that leads to failure at certain sections of the pipe now the differences between this pipe obviously are the expense schedule 40 PVC true schedule 40 PVC is super expensive now I mean I think for a 10 foot section of this stuff it's over a hundred dollars whereas cellular core PVC Schedule 40 is less than half of that it's probably I think for a 10 foot section of this stuff it's around the range of 30 to 40 dollars depending on where you live it might be more or less so as you can see the price differences are very very drastic so if you have an installer and you're paying for them to put schedule 40 PVC in the ground make sure that they're not putting cellular core in because there is a difference and if they are charging you for schedule 40 PVC make sure that's what you are getting is actual schedule 40 PVC and not schedule 40 cellular core so now let's go ahead and talk about dual wall and triple wall drainage pipe now dual wall drainage pipe this stuff is awesome I love this pipe if you live up north where you experience freezes and thaws this is a great drainage pipe for residential yard drainage now the difference between dual wall drainage pipe and a single wall corrugated pipe is dual wall has a smooth interior with added material and that increases the strength tenfold I mean I can't even make that pipe look out around by squeezing it with my hands whereas you know single wall I could easily make that pipe look out around by squeezing with my hands I could crush that thing down if I really wanted to so this makes a great yard drainage pipe it comes in 20 foot sections with a bell end so you can connect them together now you obviously want to tile tape them so that Roots have a harder time getting into the joints and unlike unlike your the wall this stuff comes in rolls whereas this comes in 20 foot sections so you know this is super flexible your dual wall is not so much flexible like this you can bend this ever so slightly in longer runs but it is not going to be flexible like your single wall pipe now triple wall pipe this is typically used in leech fields for septic systems uh this is definitely a budget-friendly pipe but for yard drainage it does work and it does hold up and it lasts and I will say this compared with let's say your schedule 20 PVC I mean this stuff is is tougher than schedule 20 PVC and not only that but for those of you who live up north and in climates with freezes and thaws this pipe will last and hold up because it will expand and contract because it's HDPE whereas you know PVC as I've stated earlier will crack so the reason this is called triple wall if you want to go ahead and bring that camera in a little bit closer so we can show everyone triple wall has a smooth interior it has a laminated exterior and then sandwiched between those two is a slight corrugated interior which gives it added additional strength all right so now if you're going to be using triple wall hdp pipe for a residential drainage system there are a few things that you need to know about this pipe now we also have a video talking about how to install HDPE for residential drainage and I'll go ahead and I'll put that in the description below a link to that video so you guys can check that out but basically this pipe would fit into thin wall sewer fittings such as this the same stuff the SDR and schedule 20 fit into now schedule 40 doesn't fit into into thin wall sewer fittings because the gauge is thicker so this pipe fits right in there but now it's not as snug of a fit as say SDR SDR has a snug fit I can't move that pipe around once it's in the hub this pipe on the other hand when it's in the hub I can move it around it has some play the reason for that is so it can expand and contract so it can move but now when you're installing this pipe you do not want to just push this in put it in the ground bury it up no you're going to have root intrusion in there you're going to have leaks it's just going to be a nightmare a few years down the road so the way you glue these two Plastics together you cannot use a traditional PVC solvent cement the reason for that is because HDPE does not bond to PVC in that manner meaning a solid cement will not melt these two Plastics together just like this will melt PVC to PVC it will not work so to glue hdp to PVC you want to use an hdp glue and this glue stays slightly rubbery in here which allows it to expand and contract but still creates a Tight Seal now this particular glue has been discontinued by Christie's so you can get it online still weld the inventory stocks last but I don't know how long that's going to be so they do make another hdp glue that works well and I'll go ahead and I'll put that link in the description below as well so this glue is supposed to be a root inhibitor as well it has some kind of chemical in it that inhibits root growth um but I would suggest any kind of hdp glue that you use to bond these two together make sure that you tile tape it up very well as as well that will create an additional layer of protection to keep roots from trying to get into the joint all right guys so I want to go ahead and just end this video by saying there is no one-size drainage pipe that fits all applications now this is a little off topic because this right here is for a sanitary system not for a storm water system but what I have right here is a old Terracotta clay drainage pipe for sanitary use for sewer this is what we first started using here in the U.S we went from the Terracotta clay to cast iron drainage pipe then to a tar paper wrapped type of drainage pipe that they did it's a terrible terrible pipe that didn't last very long um they definitely don't use that anymore and then obviously to PVC which is what they use now now these old terracotta pipes surprisingly are actually still in use around the country and still holding up but they are slowly being replaced as they break and the infrastructure gets improved over to PVC for sanitary use obviously sanitary not storm water drainage so for storm water drainage especially residential use it there is no one-size-fits all that pipe needs to be it's it's a specific pipe for your region for your climate for your application the system needs to be designed with all those in mind that way you have a good system that lasts a lifetime all right guys well I hope you enjoyed this video and you learned something today and if you want us to do more educational videos like this leave it in the comments below ask your questions in the comments and we'll go ahead and we'll compile those questions and we'll make a video answering All Those Questions we want the homeowner we want the client to be educated on what's going on and why we use the materials we use opposed to other materials that are being used out there and other ways of doing things so the more knowledge that we can spread and the homeowner can learn and understand the better we all are now when when we build a drainage system we want to use quality materials and we want to build it right the first time we want a system that is going to last you your whole life and have minimal maintenance to it you know I see things that go on with other drainage contractors and I would not recommend doing some of the things that they do it's just it's just not a good idea it's not a healthy system so there is no system that is going to be maintenance free just like there is no car that is maintenance free there is no home that is maintenance free not even your own body is maintenance free so a system is going to have maintenance but if you use the correct materials in that system and you build it right the maintenance is going to be minimal and it's going to be easy maintenance and that system is going to last forever so here at Aero General Services we want to educate everyone on why we build the systems we build and the reasons why we build them that way so if you enjoyed this video like comment and subscribe and until next time this is Aero General Services
