Flex-Drain 37043 Catch-A-Raindrop Rainwater Colander Kit, 3 x 4-Inch, White

Even with a light rain, it catches a steady stream from the downspout. Yes, the device may appear to be defective in design, but only to someone who does not understand that the water flow inside the downspout is actually mostly on the inner surface. This device catches that surface flow, directing it into the threaded hose outlet, while still allowing water to pass down through it when the flow in the hose backs up. Clever design, easy to use!

I replaced my gutters with larger ones and the downspouts were larger also. I had this model in a 2" by 3" and it works great, but would no longer fit the new downspouts. This larger version is the same design as the smaller one but works with the larger downspouts perfectly! Plenty of water, no debris in rain barrel and a quick install due to it's simple design. Highly recommend!

Works great. Water flows to our 250 gallon tote till it is full. If it is raining really hard then the heavy flow passes through the downspout as normal. This is a simple great design so why the 4 stars? Well it holds up for three or four years before the plastic inside the downspout decays. This a fairly cheap item and it works so well that I bought another and will most likely buy another when this one wears out.

This is a good, inexpensive, rain barrel diverter. Couple things to mention with this one, it works with US standard fittings (which are 4"x3" and not 2"x3"), it does not have first flush but it does keep leaf materials from being pushed into your rain barrel. If you set it to just a couple inches of incline from your rain barrel to your downspout, this has an automatic backfill function in which the rain water will push back up the hose and just dump into the remaining downspout. This is good if you have foundation storm drains and want to divert the extra back into them. The fittings are standard hose thread, so I created a hose short enough to use for this by cutting a short light duty hose in half and adding a fitting to the other end. There is a thread protector/winter cap included with this and it works well. All in all, I'm extremely happy with this.

Installs easily into a downspout to divert some of the water to a rain barrel via a short piece of hose. You do need to cut a short section out of the downspout and fit this between the upper and lower section. Pro tip - make sure you support the lower section of downspout in a way that it won't fall, but that you are able to lower it once in a while to pull this out and clear any debris that gets trapped in it (leaves, etc.).

This was a good starting point for an initial diverter but the plastic gets very brittle after a few seasons in high heat southern Summers.

I purchased this rainwater colander kit to help fill my large rain barrel (265-gallon tank). After receiving the kit, I decided to place it on a downspout coming off the back roof. My concern was the spout was facing the street, so I was hoping it wasn't too noticeable. I installed the kit on May 30, 2021. When I set up my tank, I had water from a previous container that I put in this tank. That water filled the tank to the first railing on the bottom. Since May 30th (29 days ago) the kit has gathered enough water to reach two rails above where I started. I took pictures to show 1) how the colander isn't noticeable and 2) how effective it is at collecting water. The installation took ~25 mins. I used a hacksaw to cut the spout (that wasn't quiet as my neighbor asked me what I was doing). I removed the bottom support band for the downspout. After cutting the spout I used needle nose plies to straighten any places where the metal was slightly bent. The colander was placed into the upper portion of the downspout and the lower portion was joined by inserting it into the designed seam. One addition I did was to insert two sheet metal screws through the downspout and colander to ensure it was secure. I then reinstalled the support band. I had to create new holes as the pipe changed position because of the inserted kit. I'm glad to say nothing leaks from it when it rains. I connected the hose and ran it to my tank. I waited on the first rain since I live in a two-story house and wasn't going to climb up to run water for a test. During the first rain, the hose in the tank was running like someone turned on a faucet. I also check the bottom of the downspout to see how much water was bypassing the colander. It was minimal. I would say this was a great buy. ********** Update ********** I wanted to post an updated picture of the water tank in case you question if this kit works. This is a 265-gallon tank and was installed 42 days ago. Note the picture of the almost full tank.

I thought gutters were standard. This did not fit. Then it cracked. What a waste.
