    Note: The flexible fill hose included with the DIY Rain Barrel Construction and Installation Kit is a 31-inch accordion-style hose which cannot be cut to length, but can be extended to desired length for installation.

    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")

    Our DIY Rain Barrel Construction and Installation Kit addresses these issues and offers a thoughtful, high-quality, affordable solution.
    For under $30, you get:

    *Three hole saws for drilling/installing valves and downspout diverter (2-1/8", 1-1/2", 1-1/4)
    *3/4" garden hose spigot for connection to irrigation hose
    *3/4" drain plug with cap for quick draining of barrel, linking barrels, or adding a second valve
    *Two threaded rubber seals for water-tight, easy installation of valve and drain plug
    *1-1/2" rubber seal for water-tight inlet into tank/barrel
    *31" of flexible hose to link barrel/tank to downspout diverter
    *Rubber "Flexi-Fit" downspout diverter choose either Standard (2x3" downspouts), 3x4" Rectangular, or Round (3" or 4" round downspouts). Click here for more information on the Round Downspout Diverter.
    *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. Easier than expected

      Installation was quick and easy and the Rain Bros provide everything needed. I installed 2 in about half an hour and I am going to order another.

      Extremely satisfied with the if it would just rain.

    2. Perfect...

      This Rain Barrel Diverter is amazing. Super easy installation with all the tools needed, a 20 min job. Great water catch. on 31st Jul 2020

    3. Great Kit

      Instructions were great and installation was straightforward. We've had a few rains that have filled the barrel every time with no leaks anywhere. I only wish that the hose was longer. I need probably an extra 2 feet, so right now my rain barrel is in a temporary spot until I can figure out a solution.

      Previously we were using the kind of kit where you have to cut out a section of your gutter to install the diverter (as opposed to cutting a hole, like this kit), and it seemed messy and unstable, and I wasn't happy with the spigot setup. We got new gutters and the old diverter didn't fit them, so I looked for something different. For the same price, this Earthminded kit is a much better, cleaner, and comprehensive setup.

    4. Great product and instructions

      This was exactly what I needed and at the best price. It came with hole saws and and was shipped promptly. One heavy storm and the barrel was almost filled. on 10th Jul 2020

    5. Super-easy to install- Highly Recommended!

      Ok, I am FAR from a handy person. However, I was able to set this thing up in about 15 minutes. Honestly, the hardest part of the whole project was having to go buy cinder blocks at Home Depot to set the thing on.
      The great thing about the kit is it has EVERYTHING you need - so you don't end up having to purchase extra drill bits or accessories to complete the job. It really is as easy as it looks in the video.
      Now all I need is some rain!

    6. Genius

      This diverter kit works exactly like it advertises. We are thrilled with it and its efficiency. There are other diverter kits out there but we couldn't be more pleased with the easy installation and the less invasive connection to the downspout. It also has a neat appearance. I would also like to add that when I sent Rain Brothers an email with a question, they responded right away. on 5th Jun 2020

    7. Works and is easy to install

      Works as advertised and is really simple to install with minimal tools. Read and follow the instructions! on 31st May 2020

    8. Truly just as easy as it looks

      This kit is really as easy as it sounds. The instructions are awesome and provide good tips to ensure a successful installation. I highly recommend this product!! It provides a great, economical way to begin using rain water on your property. I do suggest upgrading to the brass spigot option. I missed that on my initial order and the spigot provided is completely plastic. on 23rd Apr 2020

    9. rain barrel kit

      A bit expensive for Canadian residents with the currency exchange and the shipping costs but the product is excellent and worth every dollar. Have been using for many years and i am completely satisfied. on 29th Jul 2019

    10. Complete Water Spout Diversion Kit

      I purchased this kit to replace my current diversion kit because during a hard rain it was overflowing and leaking right nest to the house.
      This diverter has a bigger hole for the water to the barrel and is therefore much more efficient in collecting water and less likely to overflow. In light and short rainfall events it fills the water barrel much more efficiently than my old one. It works exceptionally well and with the videos and clear instructions is easy to install.
