I spent the last 20 years of my life replacing broken clay tile, corrugated elephant pipe on a golf course. None of the sdr 35 stuff was an issue. Personally I'll stick with that or sch 40.

[@marko651]

A little tip to cut the pipe straight is to put a hose clap around the pipe and then butt the hack saw up against the clap and cut .

[@braindamage396]

Great idea. I'm going to absolutely do this in the future.👍

[@HB-yq8gy]

I like the FDM but, Chuck is so honest & sincere never putting down a product or company.

[@ricos4700]

SDR-35 is the way to go. That downspout adapter fits on sdr. Strong and easy to work with. Thanks for the info.

[@matthewpresley3643]

As I mentioned in my comment about adapting schedule 40 to schedule 35 all that you have to do is buy a thin wall coupling and you can glue that inside of a schedule 40 coupling it fits perfect and glues very well and now you can adapt your thin wall into the thin wall side of the coupling..

[@tbarbuto2345]

I hear so much conflicting information on which pipe is best. It seems PVC is much better at retaining water flow as there are no corrugations impeding the speed of the water and also much easier to maintain adequate slope without bellies. This helps with keeping the drain clear of debris and minimizing residual water in the pipe which is what the roots are seeking. PVC is also much easier to clean out if it happens to get clogged. I've done a lot of research on this topic and am struggling to find a good reason to use corrugated other than ease of installation.

[@StormWaterDrainageSolutions]

Go with the green PVC sewer pipe. It’s strong, cost effective and will last. I have removed hundreds of failed corrugated systems. The corrugated pipe that is sold at the big box stores is no good. To have a quality corrugated pipe/french drain system installed costs a lot of $$$ and is only really needed in certain situations.

[@chrisvonguggenberg]

Corrugated holds some water so plants seek it out. HDPE is the best choice, flows beautifully, does not hold water.

[@bobbygetsbanned6049]

Yup, there is no right answer, apparently. I wouldn't use corrugated because with low flow it's going to collect dirt in the corrugations and too easy to have bellies that hold water begging for roots to get into it.

[@miked8227]

I have had to dig up corrugated runs before that were collapsed and clogged in spots. Do it once the right way no matter the initial cost. Cannot underestimate how important proper drainage is to a foundation, the cost is worth it.

[@sku32956]

The main draw back with PVC sch. 40 is price ,little harder to work with if you have the correct tools you can eliminate a lot of that, it will out last the big box corrugated pipe .Some jobs with out a doubt must use PVC sch. 40 .If sch 40 has root issues big box corrugated pipe will be twice as bad .

[@daveray6335]

It is also worth noting that if the fall is correct on schedule 40, hardly any water will remain in it for roots to seek. Corrugated will ALWAYS retain water...what the roots want. For some reason, Chuck never mentions this.

[@KevinBenecke]

Exactly.

Interesting and good video. Have to say, I worked in a pipe factory here in Australia and we made corrugated PVC pipe.

[@runforrestrun1965]

As I understand it, for hooking up to house or garage downpipes where you need water taken away from roofs quickly then smooth pvc pipe to roadway is the way to go. But if you have boggy areas in your back lawn, a French drain with corrugated slit pipes works well. Ensure the corrugated pipe has a sock over it and good clean stones to let surface water sink through the stones, into the slits and sock into the pipe. Great for long slower drainage to enable lawn to dry. Ensure no clay soil on top of the stones as this will simply block any water from entering the pipe to drain away and will just sit on top.

[@brianw13]

Thanks for posting this video! Was debating between SDR 35 and schedule 40 because I have to run it under a new driveway pour as well. I was worried it would crush under a driveway.

I take it you have had good success with schedule 40, and less so with other types of pipe? Trying to decide which one to use and your comment is in direct contrast with Chuck's recommendation. I like the beefiness of SCH 40, personally, but just curious to learn more of your experience.

[@johnmattu7262]

@@bmfitzgerald3 I'm a union plumber and on ALL of my personal projects I only use sch 40 and yes you can get sch 40 downspout adapters along with ANY other type of fitting. On commercial job sites I've used all the types of pipe mentioned, I install what the print calls for. I've also replaced all the other types of pipe due to excessive ditch depth and moving loads crushing these pipes, never sch 40. I believe he described exactly why he choses not to use sch 40 pipe, it's a bitch standing on your head in a 30" ditch full of slop trying to cut the heavy pipe to make a connection. The ONLY downfall to using sch 40 underground is cost, but like they say... buy once cry once.

Depends upon traffic if any, temperature range, number of bends, soil type, amount of rainfall, amount and type of vegetation.

[@kirkoneill1387]

You'd think the corrugated pipe and the thinwall PVC would snap like a twig or at least crush by how flimsy it "looks". I've actually stomped corrugated. It is strong.

[@BourneAccident]

I got an excavator and made a 100' run of 4" corrugated black pipe that I bought at Home Depot. It worked perfectly for two whole years. Then I had to dig it up because it was clogged and couldn't be snaked. So for the last few years there is a 100' open trench that carries water, but I have it staked off so no one breaks their leg falling into it. So, I have about a dozen lengths of heavy schedule 8" pipe to replace it. As soon as it warms up, I will install that pipe and be done with it.

I have a long pipe done with SDR-26 gasketed pipe that I had installed for a surface drain. It's similar to SDR-35 but has gasketed fittings that do not require glue. My installer got it from a waterworks supply house, not HD or Lowes.

He's right about getting roots. ANY pipe that is glued together and especially corrugated pipe will get roots. I have heard of some using silicone to fix the issue but I'm not sure if that works so I cannot speak on that.

[@davehastings9485]

Love watching your videos,learn a lot from them

[@Chimonya]

I wouldn't recommend corrugated with downspouts. The leaves and shingle dust will fill up and block corrugated in just a few years. Roots only get into PVC pipes that are cracked or leak from the fittings. If they aren't leaking they aren't getting root invasion. PVC is also easier to clean but I agree that thin walled PVC is probably sufficient for drainage applications unless there's a driveway or something heavy going over it.

[@prettygirlus9008]

At 14:37: everything should connect to the downspout drain. I don't think a french drain (or footer tile) should connect to a downspout drain. I've read elsewhere that if the french drain is connected to the downspout drain, and if a torrential rain causes the downspout drain to backup, then the excess water will backup into the french drain. I installed three downspout drains, each with its own line to the street and separate from the french drain (actually footer tile). I have six lines discharging to the street - three downspout drains, one sump pump discharge handling two 20-foot lengths of footer tile, one channel drain, and a 20-foot gravity-to-daylight footer tile. I used three runs of 20-foot easy flow for the footer tiles, and six pieces of 30-foot corrugated pipe for each discharge to the street, each terminating into its own catch basin at the curb.

[@frankm2588]

I agree. Also, if the rain is so torrential that the downspouts are filling that discharge with a lot of water, it will create back pressure for the sump pump, especially if the street is flooded, forcing it work harder to push against that water, and maybe fail to empty the sump.

[@jkevin1569]

No need for a separate pipes. Just run the 6 inch main line connected to each downspout drains but do keep the French in a separate run

[@prettygirlus9008]

@@jkevin1569 Yes, that would work. I used 4-inch diameter pipe for the 3 downspout drains to the street. But, like you said, joining the 3 downspout drains to one 6-inch diameter pipe to the street would have saved me some trenching.

From the sound of the cut on your hacksaw, it sounds like you installed the blade backward and you're cutting on the backstroke instead of the forward stroke.

Chuck, I learn so much from you …. I can’t thank you enough!!

[@Pw6872]

Everyone needs to keep in mind: Corrugated pipe comes in SINGLE WALL and DUAL WALL. Both are flexible to an extent (dual far less so). BUT, dual wall (smooth inner wall) will not crack nor will it collapse like thin, single wall corrugated pipe. HD carries rolls of thin single wall pipe that WILL COLLAPSE under pressure over time. For this reason, though cheap and readily available, use CAUTION when using it. Downspouts will back-up if these get crushed.

[@sawbilly2]

I have seen corrugated and schedule 20 destroyed in foundation french drains and runoff drainage. Never seen any damage to schedule 40.

[@appledrains]

We have videos showing Scheduled 40 full of roots.. cracked and broken, but the concept of this video is there are better pipe for Rainwater Drainage Thanks for your comment

[@yukonpeteneff]

Since the corrugated pipe doesn’t need coupling and elbows or other fittings, does that mean roots won’t get into it? From what you mentioned about the rigid pipes having roots get into the joints of these systems, does eliminating the joints with corrugated pipe also eliminate the roots issues?

[@JSLEnterprises]

roots have the easiest time getting into that water and debris retaining garbage.

[@joeshmoe7789]

Corrugated pipe has T's, Y's, etc that are loosely connected and therefore are subject to leaks or roots. Schedule 40 joints are welded with cement and don't leak as stated here. They're the same joints the inside walls of most houses. How often do drainage pipes leak inside the walls of houses? It's the strongest vs future large tree roots. You can seal other pipes if you need to. Corrugated needs to be checked every 6" for fall in and bellies when small amounts of fall are all that's available. It also always has standing water inside it, even with plenty of fall. Straight pipe doesn't retain water.

[@sofjanmustopoh7232]

Corrugated pipe retain dirt n water. Can have small crack that is penetrated by roots . Also corrugated coupling , Y and T are loosely fitted . Root would get in corrugated like in no time

When my house was built, the builder put a corrugated gutter drain under the front yard. It failed totally in about 4 years. I dug it all out and installed Sch 40. Twenty-five years later it remains root and clog free. I would not waste a nickel on corrugated piping.

[@sawbilly2]

I have seen roots and damage in all the pipes you are discussing in this video. A french drain under 8 feet of topsoil is a stop gap at best, especially with no method of cleanout. Sediment cloth over time will eventually clog and totally stop the flow of water into any type of pipe. Schedule 40 and SGR-35 are the only pipes you can clean out effectively that i have used, Corrugated pipe almost always in my opinion is the most likely to become distorted and clogged and rendered useless. I have been building and dealing with water problems for 28 years in the mountains of WNC. I still don't think i have the answer on the perfect pipe or best method, to keep a french drain operating at peak efficiency indefinitely.

One hint using any hand saw-to get a straight cut point your index finger forward and rest on saw.

The recipo saws shoe should always be touch the work

[@GlobalistJuice]

That corrugated pipe collects shingle dust washing off the roof and is a trap for leaves/dirt (and it traps obscene amounts of water in those grooves as well) - good luck keeping it clean as it will fill-up with crap and clog before you get around to any annual maintenance - I wouldn't use it unless I was desperate and it was my *ONLY* option in a home flooding situation! I would not consider it for French Drains for the same dirt *and* water trapping/clogging reason, PVC + lots of gravel is the way to go there. Water runs best along smooth surfaces, why throw that undisputed science out the window and use pipe that isn't smooth to remove your water problems?

[@loganp1354]

Exact thought everytime I see it used. I could only imagine using it on serious slopes (>50%) where the angle and force of water flow would allow self cleaning of the pipe throughout the year

One more question: When I core aerate this spring, will the aerator punch holes in the PVC pipe?

[@HumbleWarrior7]

As someone who used to do aerating for a landscape company, I’ll say the plugs are usually 2-3” long. If your pipe is a safe distance deeper it shouldn’t be a problem. Walk and tow aerators are usually significantly lighter and shallower than ride ons which sometimes use a hydraulic press. However the ride ons are able to pull better plugs in tough soil.

[@SafetyZar]

Some commenters make an argument for schedule 40 pipe. Schedule 40 is hands down stronger than the others but...SDR35 is the standard pipe called out for use for underground sewer lines. If it is good enough for sewer lines than it should be good enough for drain lines as well.... as with all decisions the application must be kept in mind. If you are going to drive over it or put a rockery over a pipe with minimal coverage it is going to need to be stronger. Chuck obviously has a lot of experience and if he has good success with coorogated pipe than you probably will too. (Unless you have minimal coverage, poorly drained squishy soil, are passing through trees or may apply excess pressure to it. (Think, roof replacement or any other delivery. (Dumpster, soil, concrete etc.)

[@ryanglaser5336]

The way corrugated piping is being promoted you would think this was being put out by APC American Plastics Council. It's inferior in terms of performance, does not pass solids due to the ridges, cracks, tears, breaks, fills with mud and doesn't last in swampy environments. Replacing it multiple times over the lifetime of a building does have a carbon impact, although PVC polyvinyl chloride is poison plastic. ABS black plastic pipe is better for the environment in terms of dioxin emissions from the PVC lifecycle. Don't waste time burying cheap corrugated pipe, even if it is tempting to use for ease of installation at a fraction of the price.

[@ArieteArmsRAMLITE]

Lenox 4012. Hacksaw. Ebay.

[@jgren4048]

In my experience, picturing you root clearing a drain pipe = blowing out the side of corrugated, or schedule 20. However if it’s deep enough, schedule 20 properly backfilled will be just fine. Corrugated is just garbage. It fills with trash way too easy, does not retain its level but has highs and lows unless your trench is particularly done right. You were complaining about the little ridge in schedule 40, corrugated has one every inch or so. It’s Used only in a pinch. Under driveways I would use schedule 40 or the green pipe. Green pipe is best IMO

You need to use various fittings to make turns and glue them. You also need to glue couplers to lengthen pipe. Trenches have to be dug almost perfectly straight. Corrugated bends and the few connections you make just snap together.

[@confidentlocal8600]

What's best for inside a crawlspace? I have a tall crawlspace (with some standing room) where I've already trenched around the perimeter. Most of the trench is only 6" deep, but in one place the pipe will be buried under about 18 inches of gravel along the footing. Corrugated will be easier to maneuver in the space, but will it hold up to 18" of gravel? I also have two pits that I'd like to connect to each other with a pipe that will run through the middle of the floor, where it will be walked on, with about 2 inches of gravel cover. Will corrugated hold up there?

[@mewho8519]

Perforated corrugated pipe is good for slowing and absorbing surface water that cant drain out flat or low yards. The type of pipe to use depends on what you are trying to do with the water. Pvc for fast drainage of downspouts and corrugated for modified french drains and allowing surface water to disperse into the ground where drainage isnt an option its just give the water somewhere to be other than the surface.

Good information Chuck! One question, at 0:43 it shows the PVC pipe is schedule 40, but I also see “DWV”. Is that pipe a regular schedule 40 or a DWV type? I’m a little confused. Thanks!
