As a drainage contractor, one of our biggest complaints about downspout cleanouts was that they would spray and splash up against the house, which risks all kinds of damage to the home’s foundation.
We worked closely with engineers to create a downspout leaf filter and vented cleanout that would contain roof runoff water. This filled a much needed gap in the drainage market. I wish I had this part my whole career.
No More Splashing
Water falls through our leaf filter cleanout without any spraying or splashing. We designed it with a door that funnels the water through buried downspouts. When water enters the cleanout, it splashes off the inside of the door and sends the water down through the system.
Also, the shape of our vented cleanout allows water to funnel gradually. The fluid dynamics are second to none.
Vented Cleanout and Leaf Filter – All in One
First and foremost, this is a vented downspout cleanout, but we also built it as a leaf filter with a removable screen.
Patented Vent for Cleanout
Downspouts are powered by gravity. During a heavy rain event they can become full of water if there is nowhere to vent. Venting your downspout at the house will allow that water to keep velocity and flow at a higher speed.
Also, if you have a freeze up or if grass grows over your popup emitter, you’ll still be able to vent the water at the cleanout.
Removable Screen for Leaf Filter
This is the first cleanout on the market with a screen that you can remove, if desired. However, if you are trying to filter out leaves and large debris, we do recommend that you keep the screen in place.
You can also remove the center of the screen when you need to access the downspout line. This makes it easy to run a camera, a garden hose or a heat cable in the winter to keep water from freezing in the line.
Fits Any 3 or 4 in Drainage Pipe
No more shopping around to find different adapters and parts that fit. Our downspout cleanout leaf filter will connect to any 4 in. pipe.
4″ Corrugated single wall pipe
4″ Dualwall corrugated pipe
4″ PVC SDR 35
4″ PVC Schedule 40
4″ PVC Schedule 30
4″ Triple Wall septic field pipe
3″ Corrugated single wall pipe
3″ Dualwall corrugated pipe
3″ PVC SDR 35
3″ PVC Schedule 40
3″ PVC Schedule 30
The downspout will snap right in to our leaf filter cleanout with no need to seal or glue it.
Made in the USA
We are proud to say we manufactured our leaf filter cleanout in the USA – right here in our hometown of Michigan.

Update 08/2025: Just got my roof shingles replaced and I am glad I have these French Drain Downsprout cleanout installed. After a rain pour, I decided to go clean up and I found over 30 roof nails all caught in the plastic line guard/filter. Glad they are there as these nails would have just sat in my drain pipes or worse yet, drain out on the small creek where some of kids play. Super thankful for these.
I am a Youtube follower of the French Drain Man channel and ordered 5 x Downsprout cleanout leaf filters. The quality of the product (Made in USA) is top notch, I know they will last years to come.
I finally got the chance to install a couple of the French Drain Man's Downspout Clean-outs with Leaf Filters that I bought from them last year. They are very functional and look great IMO, so I'm buying more along with several more of their drainage products. Very happy that these products have been conceived, designed and made in USA. Thanks FDM!
We recently have had The French Drain man complete 3 underground gutter drains, with downspout cleanout, catch basin, and pop up drain. They were installed under cement walkways already in place. From the moment they arrived you could see they were very organized and meticulous about their business. They have what they do down to a science. There was no guessing as they had a plan in place for our yard before they arrived. They used top notch products, and completely put everything back and cleaned up as if they were never there. Thank you French Drain Man.
I purchased (5) of the French Drain Man Downspout Cleanouts with Leaf Filter and am very happy with the product! They are well designed, well manufactured, and look nice on our house. After three months of use I am very happy with the performance. They do a great job of filtering leaves without affecting water flow, and have no external splashing. I will be ordering additional filters for all of the downspouts on our house.
They have everything I needed to really do my downspout drainage right. With the downspout cleanouts, catch basin and excellent pop-up emitter I can now handle Florida's summer thunderstorms and get the water far away from the house. Excellent training videos to help a DIYer.
The leaf filter arrived on time and looks very nice and solid. The opening is slightly larger than the 2x3 downspout pipe making it easy to fit. The bonus pipe joint is very pretty and versatile allowing corrugated to PVC pipe so that I don’t need additional joint. Compared to big box and local landscape supplies, the French drain man products are just much much better. Really hope there is a distribution center in California to give people access to the well designed and built storm drain pipes.
Recently purchased the downspout leaf clean out. Was very easy to install and anticipate it making cleaning out downspouts and storm drains much easier.
