  • Product Description

    Our 3x4" Flex-Fit Downspout Diverter collects rainwater from 3x4" gutter downspouts and feeds it into a rain barrel.  When installed with the Flexi-Fit Fill Hose and Inlet Hose Seal into the side of your barrel, it provides an overflow mechanism that feeds extra water back down your downspouts. 

    • Easy to install!  Simply use a 2-1/8" hole saw to drill into your downspout and the Flexi-Fit Diverter fits right in
    • Large, 1-1/4" outlet allows plenty of water to pass to your barrel/tank (connect with the Flexi-Fit Fill Hose and an Inlet Hose Seal for a watertight fit)
    • Large overflow opening allows water to easily pass back through the downspout once your barrel/tank is full
    • Works with 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 if you need more length than 31")

    -(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 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!




    Fixed Shipping of $3 per diverter on US orders!  International orders will be charged an additional fee depending on shipping address.

    3. rain diverter: installed

      I rec'd a 3x4" diverter yesterday and installed it today. My install deviated from the recommended a little bit... I put it in a bit of downspout that I had been removing - putting a custom made bit of downspout at the height of the top of the rainbarrels. I had the luxury of having a 5' section of downspout that I could remove and work on apart from where it was installed.

      Installation was as advertised - drill a 2.125" hole with a hole saw and slip it in and screw it in place. Now, looking down through my downspout, light was visible as the soft rubber of the diverter didn't quite conform to the longitudinal corrugations of the downspout profile. I added some sealant to fill these gaps as I am rainwater-greedy! I only catch water from a small area of roof which is usually enough to keep our barrels filled. With some of the rain going through those gaps, not sure if I would have enough, so added the sealant.

      That's that. I ran a short piece of 1' pvc to run to the first barrel and now I'm waiting for the first rain.

    4. it actually works

      Easy to install. After much research I choose this diverter because of the simplicity, cost and ease. KISS. I have a 4” downspout with covered gutters, a great fit for this product. on 23rd May 2020

    5. Easy installation

      I had the smaller version of these and by far the larger one captures more rain. I have 8 rain barrels now. To save the flexibility of the diverter I remove them at the end of every season and cover the hole with the flexi cover. Thank you for having the correct products at reasonable prices!!!!! All of the accessories for rain barrel installation are proper and work great!! on 2nd Jun 2019
