  • Product Description

    We at Rain Brothers, LLC have been designing, constructing, and installing rainwater harvesting systems -- both residential- and commercial-scale -- in the Ohio Region for over eight years, and we have used virtually every rainwater downspout diverter on the market. With the diverters on the market, there are recurring problems, including:

    1) Difficult installation

    2) Insufficient outlet size

    3) Insufficient overflow, causing diverter to back up drainage

    4) Working only with the smallest downspouts (i.e., 2"x3")

    Our Flex-Fit Downspout Diverter addresses these issues and offers a thoughtful, high-quality, affordable solution by being:

    1) Easy to install; there is no need to cut your downspout.  Simply use a 2-1/8" hole saw to drill into your downspout and the Flexi-Fit Diverter fits right in

    2) Large, 1-1/4" outlet allows plenty of water to pass to your barrel/tank

    3) Large overflow opening allows water to easily pass back through the downspout once your barrel/tank is full

    4) Works with both 2"x3" and 3"x4" downspouts


    *Required for installation:

    -(1) 2-1/8" hole saw

    -(2) 3/4" self-tapping philips screws (included)

    -(1) Fill hose (1" PVC will also fit inside diverter)

    -(1) Hose seal

    -(1) Winter Cap (if you are in an area where temperatures get below freezing)


    Installs in three easy steps:

    1) Drill hole in downspout (you will need 2-1/8" hole saw for installation, which you can purchase here).  For 2"x3" downspouts, drill hole in front of downspout.  For 3"x4" downspouts, drill hole in the side of the downspout (3" side).  Ensure hole is level with inlet on barrel.  For round downspouts, try our Round Downspout Diverter.
    2) Insert diverter and fasten diverter to downspout with self-tap screws
    3) Attach fill hose to diverter and into barrel hose seal, and start collecting rain!

    1. Perfect

      After considering all the different solutions, your diverter was the easiest to install and makes the most sense.
      Thanks for spending the time on design.

    2. Wonderful

      this product if so much better than anything else I researched - so easy to install, amazing and works great! I wish I had more downspouts to put them in. Thank you so much. steve on 29th Aug 2015

    3. Easy to install

      So far doing the job with a good seal. on 24th Aug 2015

    4. rain water cololection

      I set up a rain collection barrel 3 yrs ago with this product using one diverter in a 3x4 in. downspout and before the yr was over I added a 2nd diverter on the other side of the spout to double the flow into the same barrel. It worked so well that I did the same with another collection barrel this yr. This is a fantastically simple and effective diverter product, as-well-as, the winter cover cap. on 3rd Aug 2015

    5. This diverter is a key component to making a mosquito-free rain collection system


      The link I included in my diverter review (dated July 25) doesn't work, possibly because YouTube is case-sensitive and the reviews appear in all caps. Anyway, if you do a search for the below phrase, it should get you to my video which features the Rain Brothers diverter, which are great!

    6. Great product. I have 2 and will get more. Here's what I did...

      After you put the diverter in place, you can pretty much forget about it. I set up my first rain barrel (an IBC tote) in 2013 and it has performed exactly like I wanted. I am going to set up a 3rd barrel so I'll be ordering another diverter soon.

      Here's how I set mine up. See the description for part numbers.
