  • 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 nearly a decade, 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 inlet size into the barrel/tank
    3) Insufficient overflow, causing diverter to back up drainage
    4) Working only with the smallest downspouts (i.e., 2"x3")

    The Universal FlexiFit Downspout Diverter Kit addresses these issues and offers a thoughtful, high-quality, affordable solution. It connects your existing rain barrel to a high-quality downspout diverter system.
    For under $30, you get:
    *Two hole saws for drilling/installing valves and downspout diverter (2-1/8", 1-1/2")
    *1-1/2" rubber seal for water-tight inlet into tank/barrel (note: hose must be installed through side of barrel for overflow mechanism to work properly)
    *31" accordion style Flexifit fill hose to link barrel/tank to downspout diverter
    *Rubber Flexi-Fit downspout diverter : choose either Standard 2x3", Rectangular 3x4", or Round (3" and 4" round downspouts). Click here for more information on the Round Downspout Diverter.
    *Two self-tapping screws
    *A winterizing cap for quick and easy winterization of your downspout.

     Flexi-Fit Downspout Diverter installs in three easy steps:

    1) Drill hole in downspout (hole saw included in kit).  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.  Click here for more information on the Round Downspout Diverter.
    2) Insert diverter and fasten diverter to downspout with included self-tap screws
    3) Attach fill hose to diverter and into barrel, and start collecting rain!

    1. Highly Recommend this prouct

      I purchased this product and when it arrived it was very easy to install. They provided all the necessary drill bits and screws to attach the diverter to the downspout. I would buy this again over and over. on 24th Jul 2020

    2. Everything You Need

      Great kit! Everything you need. Excellent price and easy installation. Fast shipping too. Thanks Rain Brothers on 28th May 2020

    3. Excellent product

      I installed this kit a few days ago and the rain barrel is already full! It was easy to install and works perfectly. on 24th Aug 2019

    4. Reasonably-Priced, Well-Designed and Easy to Install Rain Barrel Filling Kit

      The kit had all the items needed, including the hole-drill bits making the diverter easy to install. The reason I gave the kit a 4-star instead of 5 stars, is my concern about the durability of the "accordion" hose connecting the downspout to the barrel. I think a more durable flexible hose might be more durable. Otherwise, this is a very clever product and comes with clear, easy, and complete instructions. on 18th Jun 2019

    5. Amazing Rain Diverter

      I recently ordered and easily installed the rain gutter diverter and hose hook up to my barrel. It rained the next day, filled the entire 50 gallon container up to the level of the hose entrance and excess water diverted back to the gutter as it should! Works really well! Good job Rain Brothers! I like the fact that it works as described and shown on the video. on 16th May 2019

    6. Fast Shipping and Great Product

      The rain downspout diverter kit for my 3x4 gutter worked perfectly. It had everything I needed to connect my rain barrel and the two included hole saw drill items worked great. Item shipped the very next morning after placing a late night order. Arrived in 2 days via USPS.

      Thank you!

    7. Great Product

      This was so simple to install. I did not have to cut my downspout in half. Works as advertised. Great Product . Lucky to have found it! on 30th May 2018

    8. 2nd Purchase

      We had such good luck using this kit for our 1st rain barrel (purchased at a Soil and Water Conservation Service event) that we got a 2nd barrel and a 2nd kit this year. Easy hook up and after last night's rain have plenty of water to keep new plants moist without dealing with a hose. on 25th Apr 2018

    9. What a great rain water diverter!

      We've had a rain barrel for at least a year but hadn't installed it because of the difficulty of installing a diverter. We ordered the Flexfit diverter kit last week and installed it over the weekend. It took about 15 minutes to level the spot where the barrel was to sit, figure out where to drill the holes in the barrel and gutter, and install the diverter kit. It happened to start raining shortly after we set up the rain barrel. We went outside and looked in the barrel maybe 30 minutes after it started raining an it was already full! We were super impressed. The only problem we had was that we couldn't push the end of the hose fully into the hole we cut in the could be that the barrel flexed as we were cutting the hole and the hole didn't come out quite the right size. But it still worked fine. on 5th Sep 2017

    10. Rain spout diverter - Installation was so easy!

      Directions and installation of the diverter were very explicit and so easy!! When I get another barrel, I will certainly order another kit! on 17th Jul 2017

For this project, you'll need: *(1) Shovel *(1) Level *(1) Tamper (you can also use a concrete block for compaction if you don't have a tamper) *8" x 8" x 16" concrete blocks (4 per layer) *(1) 24" x 24" concrete walk slab (or four 12" x 12" slabs) *(Optional) Small gravel (1/2" and smaller) For more information, please visit our website: or Please subscribe to our channel for more rainwater harvesting tips.
