A Basin Designed to Change the Game

Sediment Trap Keeps Line Clean – Shingle gravel and sediment can quickly clog drainage systems. FDM’s inline catch basin is designed to mimic a pipe belly, allowing the sump to collect and hold sediment before it enters the drain line.

Large Sump, Slim Profile – A massive 1-gallon sump captures sediment before it enters the line, while the slim 5″ profile fits easily inside a trench without digging oversized holes or using heavy equipment.

Built for Freeze-Thaw Conditions – The basin top is shaped like a 4″ drain pipe so water continues flowing when the system maintains a 1% slope—preventing standing water and winter freeze-ups. The sump is built to handle freeze-thaw conditions without cracking, made from 100% virgin HDPE with no fillers or recycled materials for maximum strength and longevity.

Pilot Holes for Optional Drilling – There are 6 pilot holes at the bottom of the basin, allowing installers to easily drill holes if they want water to leach into the surrounding soil.

Easy to Clean – The sloped sediment trap prevents debris from settling in the center, making cleanup easy. Simply remove the grate, vacuum out the sediment with a shop vac, and snap the grate back in place.

Everything You Need to Know about French Drain Man's Catch Basin If you’re installing a drainage system and want it done right, this is the complete breakdown of how the FDM Catch Basin (Sediment Trap) is designed — and how to install it properly. In this video, Robert Sherwood walks through: 🔧 Proper installation technique (no humps, no bellies) ⬇️ Why the basin should hang at the bottom of the trench 🚫 Why you should NEVER raise the basin to grade 📏 How risers solve grade issues the correct way 🕳️ Why drilling holes + pea stone underneath matters ❄️ The “pop-up lid vent” hack (freeze & clog backup protection) 📦 4" and 6" basin options explained 📐 How to create slope on flat yards using stacked risers 🪨 Why this basin is engineered as a true sediment trap ♻️ HDPE vs. styrofoam catch basins 🏆 Patent details and plug-and-play design Why Sediment Traps Matter Downspout lines — especially from shingled roofs — carry shingle gravel and debris. Without a sediment trap, that material builds up in the pipe and eventually clogs the system. The FDM Catch Basin is shaped to mimic pipe flow while allowing heavy debris to settle in the basin instead of your line. That means: ✅ Less clogging 🧹 Easier maintenance ⏳ Longer system life It’s designed to hold up to a gallon of shingle gravel (and larger models hold even more), giving you time to shop vac it out before it becomes a problem. Built for Contractors & DIYers ⚡ No screws 🧩 No glue 🔄 Slip-fit risers 📈 Stackable height adjustments ⏱️ Fast installation Contractors save time. DIYers avoid common mistakes.

Our new inline catch basin connects so fast I can't blink. I can't take the camera off these guys because I'll miss the connection. We have a triple patent-pending catch basin that is going to change the industry. It is the fastest connecting catch Basin. It is the easiest to clean. It is the easiest to install because it's only 5 inches wide and fits in a Groove made by a trencher. It holds five to ten years worth of shingle gravel. Meaning it doesn't need to be cleaned but every five years. In this video we're going to show you how quick it connects and how easy it is to work with. ⭐️ Get FDM's New Catch Basin ! ⭐️ https://frenchdrainman.com/new-fdms-catch-basins ========================================== More Downspout Products 👇 New!

It basically makes all the inline catch basins before this obsolete. We designed an inline sediment trap it's only five inches wide so it's really easy to put in the ground. You don't have to take a pick axe and dig a five gallon hole. Everything is set up for convenience. Like many contractors we tried everything on the market. The industry had been using a lot of septic system boxes for yard drains - because it's all we had. But when the pipe is lower the problem is you're not going to have a sump to collect debris and sediment so it's going to fill your pipe with debris and sediment. We answered it with a sediment trap. You never ever lose your sump. We designed a larger gap so that all the debris falls before the water makes it to the other side - the outlet. ======= French Drain Man – Michigan’s Yard Water Drainage Experts.

I have purchased three of the downspout kitswhich have the 3 inch hose, pop up emitter, dowspout adapter and catch basin. All parts fit well. I was able to install with no problems. Two of the installations required digging under sidewalks. I have four more downspouts that I will use the FDM kits on. I live in Maine so I needed to drill holes in the catch basin and emitter to drain the system.

Phenomenal products!! I have 4 downspouts, 3 of which were improperly buried by landscapers. I have replaced 2 of them myself with the 3" Premium PRO Kit for Buried Downspouts. AMAZING!! What a difference! This was a fun little project, time and effort will vary depending on your yard conditions. Great before and after results, I find myself grabbing an umbrella during rains just to see it in action. I love it. I'm going to replace the other 2 downspouts this spring, one of which is PVC and froze this winter, I wish I did that one first. I highly recommend getting a catch basin also, it's crazy how much shingle debris it catches. Yes, they are a bit pricey relative to the junk sold in the big box stores, but you definitely get what you pay for. Do it right the first time and it will be cheaper in the long run.

Exceptional Customer Service! I was in dire need of x2 4" Catch Basin risers to complete a job that I wasn't able to complete this past weekend so I called French Drain on Tuesday morning and the person I talked to was very nice and professional she told me the shipment will take 5 days to ship so I asked if they had a dealer in California that I can call and they gave me a number to Old Home Specialist in Sacramento Ca. and I called them and left a VM and by noon Brent Bennett (Owner Of Old Home Specialist) called me back and he went out of his way to ship me these two risers and dropped them off at Fedex and I had the parts by Thursday and I was able to complete the job on Saturday. Oh! and Brent didn't even charged me for the shipping or the part. Brent said that it's important for him that his customers succeed. Wow! want a honest and caring Man Brent is. I'm not joking, I don't usually write reviews but I really needed to write this one. I would definitely call Brent back in the future.

Thank you French Drain Man

These products are excellent. I used both 3 and 4 inch solid pipe for my downspout system--the leaf catchers on each downspout (excellent product) pop-up emitters with turf restricters and catch basins with turf restricters. The tape they have is great too. The ordering process was simple and they even commented on my design. Shipped right to my house. Everything was perfect. My yard still needs a French Drain system installed and I will be using French Drain Man products for that job too. I have a video of the job but its too large but I'll keep trying to get it posted. It was a big job--about 200 feet of system.

FDM provides the best pipe and drainage systems out there. I have peace of mind install installing the systems because I know the pipe will last forever the leaf filter and catch basin will keep it running clean for many years. It is already helping with the bugs in my basement and will probably help reduce mold too. They are very responsive to questions and concerns on their YouTube channel as well.

I bought three standard (for 2x3 gutters) Downspout Cleanout and Leaf Filter units, plus three 4" catch basins plus fittings to adapt to thin wall SDR pipe, and everything worked out great and was of very high quality and well designed. The photos are two of the clean out/filter units.

I had the catch basin positioned just before a Flo Well dry well, with a pop up emitter on top of the catch basin so it would overflow if the dry well got completely full.

One tip that I found, was to use the SDR pipe with the large built in coupling bell end at the top so the height of the NDS pop up emitter could be easily adjusted.

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.

Very happy with the product I received. I'm using the popup emitter with the catch basin for my downspouts. The flap style on this emitter allows leaves and debris to easily flow out or collect in the catch basin with less worry about clogging and plugging up the emitter. A bit more expensive than other popups but the clog free nature is good insurance in my wooded location. I'm ordering two more today.
