Great video! Thank you for the step by step instructions. Based on this and other videos, would it be correct to say: Double barrel 3” pipe French drain = 3/4 rock Double barrel 4” perforated French drain with solid pipe yard drain on top= 3/4 rock Double barrel 4” perforated French drain (no other pipes in trench= 1 1/2” round rock. I recognize every job is a little different. Just trying to understand the general approach. Thanks!
I live in New Jersey, do I need to have the pipe below the freeze line? Also, I am going to run the pipe to the woods in my back, how far should the drop be for a 75ft run? Thank you so much love the videos!
hi there FDM! thank you for your informative videos! really inspiring and useful. Can you help me - i have a trench which is only 5.5 metres long with w slight right angle to the outlet in an inspection chamber. How do i ensure that I have a 1% slope throughout the run? Many thanks
Also, How far apart would you recommend that the burrito wrap be pinned? It appears that the guys are pinning the wrap about every 24". Or is every 18" better? Thanks!
Great video. I was planning on running one 4" perforated pipe, and one 4" solid downspout pipe burrito wrapped in the trench. For the discharge I was going to wye the perforated into the solid out to a pop up. Does this sound right? Would I add any benefit to adding an additional catch basin shortly after the wye fitting? Thanks!
NICE. I have a good 100' across my back lawn sloping towards my house. I can use this. Previous owners added drains on each end of the lawn and down the side of the house and out the front lawn. May I connect your 3" pipe with this existing drain?
Just curious, if I followed all your instructions here but I wanted an OPEN French drain (no sod back on top), wouldn't the addition of that quarter inch of sand on top slow down the water infiltration rate compared to using ONLY stone on top (because that stone has larger voids than the sand does to allow surface water in better)? So, I am thinking of following ALL your instructions and materials with the 12" depth and two 3" pipes BUT I would like to SKIP the layer of sand on top AND use the larger stone that you normally use for a 4" drain and there will be NO sod on top? Does this configuration make sense? THANKS for these great videos!
If you're doing open, I don't think you'd want the sand on top. The whole point of the open drain is that you want faster flow. That also means you'd probably want to go with two 4" pipes instead of 3", to accommodate that extra flow. One inch doesn't sound like much, but you square the radius (remember ) to figure the cross section: the 4" pipes would have a combined 25-square-inch cross section, while the 3" have just over 14 square inches. And since the outside of that cross section is slowed by the corrugations, it's probably more like a 2:1 ratio of how fast the water can move in 4" pipes.
@@montyharder3663 I agree 4" is better and it has more perforations per valley circumference and higher volume but I like the idea of only going 12" down instead of a min. of 14" as French Drain Man has outlined in other videos. What downside (possible problems) might there be in using two 4" pipes but only going down 12" (all other parameters being as he stated) except I want an open French drain?
@@michaelt1349 I'm not a professional like Robert, but it seems to me that in an open drain, you could go as little as 7 inches at the shallowest, because you only need a few inches of rock on top of the "burrito wrap". Just enough weight to hold the pipes down, really.
I want to put in a french drain (with 4" piping), but I plan to add a gravel walking path over the top, instead of grass. Do you have any tips/suggestions? -Cheers! :-)
I have one downspout on the back of our house emptying a ton of water that just stands on the lawn. I want to bury the downspout with a pop-up emitter next to a new french drain. I don't have access to a storm drain for discharge. What are my best options?
If you already had a French Drain installed and you suspected (perhaps a year later or so) that critters might have made a nest in the pipe, could you run a plumber's snake through the pipe without damaging it? (assumes you have an access port in the line) Thanks!
@@FRENCHDRAINMAN Appreciate your timely responses but if I don't have a power washer (I don't), should I avoid using a plumber's snake as it might get caught in the plastic?
I want to stop rain water from penetrating my 100 year old foundation wall by making a French drain 4 feet away from foundation. Front wall of the basement is 4-5ft in ground-which size pipe should I buy from you and how deep should I bury it?
You mention that you go no deeper than 12” in this install. What is the minimum starting depth for a 3” system with grass? How about minimum depth for 3” open French drain with no grass?
I think I just noticed that the 3" pipe only has 4 slots (perforations) per valley circumference whereas the 4" pipe has 12 slots (perforations) per valley circumference. Is this correct? Thanks!
Hi boss!! I want to do what you show around my 100year old house, front foundation wall is in ground and it leaks during heavy rains. I want to catch that water before it gets to the aforementioned foundation wall. The whole yard is at a slope where the road is higher than the backyard… Can we video a call so you tell me what to order from your site and how to install it? Property is 400ft long.
i really like this idea, about making it easier less digging etc. however i need my drain to about 38 ft. so your kit is only made for 25 ft, doesnt work for me. now if i have to buy two kits it's double the cost...at that point i'll just buy the black stuff from home depot.
Weeds grow at the edge of rip rap. It also makes someone's front yard look like a freeway embankment. You have to spray round up along the rip rap. Rip rap is for erosion control. We will connect to this drain at a later date and add on to the system.
Love this kit!! Appreciate how quickly you respond to the questions from us DIYers!❤
Thank you

You sound like you’re from little falls nj :)
You build them with slope, and they do not hold water. So they can be built shallow in the frostline.
Have you experimented with running three 3 inch pipes at the bottom for air pruning? Or running a quad pack of 3 inch for the same reason?
Yes, we have. We actually used 6) 3" pipes in a french drain for air pruning. It was an easy installation. 3" is user-friendly.

Great video, is standard to run two discharge lines when working with 3 inch pipe?
You can wye them together on short runs 150 feet or less. The 2nd pop-up emitter allows for access.

You can use only stone for an open french drain when you have a situation where there will be no sediment

7 inches deep for a starting depth is recommended.
is the "inlet" side of the piping just simply capped off?

Best of luck. That pipe will collapse, it'll also split, and animals like to dig it up and chew on it because it's recycled materials.
Did I miss something what happens to the beginning end ?
You must have jumped around. Watch the whole video without skipping around.
