     Note: If ordering bulk quantites of this kit (20+) please contact us for the best price on shipment to your location!

    Note: The flexible fill hose included with the DIY Rain Barrel Construction and Installation Kit is no longer 3 feet long. It has been replaced with a 31-inch accordion-style hose which cannot be cut to length, but can be extended to the 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 new 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" gate valve/garden hose spigot for connection to irrigation hose
    *3/4" drain nipple with cap for quick draining of barrel, linking barrels, or adding a second valve
    *Two threaded rubber grommets for water-tight and easy installation of valve and drain plug
    *1-1/2" rubber grommet 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 Rectangular (2"x3", 3"x4"downspouts) and Round (3" or 4" round downspouts). Click here for more information on the Round Downspout Diverter.
    *One "do not drink water" label for your new rainwater harvesting system
    *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!

      I just bought another kit. Bought one last summer and the wife wants another on in front of the house. So simple o build takes minutes. A 10 yr old can make one of these. Thanks on 20th Apr 2015

    2. So easy

      The kit provided everything needed to quickly set up my rain barrel and so easy too. on 20th Apr 2015

    3. Easy to install

      I bought this kit last year and was so impressed with the ease of installation and the way the system works, that I bought parts this year to add more rain barrels. on 17th Apr 2015

    4. Easy to install!

      Received the product promptly and installed it with no issues. The directions were clear and the best thing about this product is that the installation is very neat and clean, no screens or moving your downspouts around. I liked it so well that I ordered 2 more! Can't wait for the rain to come. on 15th Apr 2015

    5. neat and simple

      This kit includes everything needed to install your rain barrel. It is very neat and tidy once installed as opposed to the bigger and bulkier hoses. The ability to remove the hose from the spout and install a plug for winterization is an added plus. on 14th Apr 2015

    6. First rain in Pasadena December 2014 and collected about 300 gallons!

      Easy to set-up, used six plastic food barrels to collect over 300 gallons of water. Small two car garage and a little over two inches of rain....resulted in six full 55 gallon barrels! Use extra parts to connect barrels and still have three more barrels to set-up off house down spout. Don't know how long my rain water will last in Southern California....but every little bit helps. on 5th Dec 2014

    7. downspout diverter

      Great product, easy to install. My only problem
      was location of barrel. Down spout is located in walkway and barrel had to be around the corner in the yard. I found a 90 deg. pvc plumbing fitting that fit perfect and it kept the hose from sweeping into the walkway .Could a 90 deg. fitting be included in your diverter kit ? Thanks Ron L.

    8. This product made the project easy and quick to complete.

      This is a must buy for anyone looking to construct a rain barrel. The product works perfectly and I will be buying this kit again for the other side of the house.

    9. This is the 3rd kit we have ordered

      Time to put the rain water to use, OH THE GARDENS WE WILL HAVE KNOW.
      MY husband did all the work in no time flat and he didn't even complain,
      Thank you Rainbrothers .com
