A Clever Rainwater Diverter


The average roof sheds 160 gallons of rainwater per hour during a moderate rain fall. Rainwater is better for your garden than tap water: it is at ambient temperature rather than being cold, and it is not chlorinated or treated with chemicals.

The Garden Water Saver, is a device that attaches to your home’s downspout, and allows you to use any container as a rainwater barrel. It diverts rainwater until the container becomes full, and then it automatically shuts off. It will fill a 55 gallon rain barrel in 2 to 3 hours during a moderate rainfall. The kit is available for $19.95 from Garden Water Saver.

    Hi, great site. Do you know of any manufacturers of rainwater divereters to fit 50mm round downpipe. I have installed Marley Miniline rainwater kit but cannot find a suitable diverter to get the rainwater into the water butt – short of drilling a 50mm hole in the lid!

    Thanks for any help

      Look out for Jardesign and Jardieco products from France. I am busy translating their website which should be online soon in English.

    I needed my diverter to stop overflow and to stop mosquitoes. The garden saver worked for this fine. The only problem I had with this diverter is that it broke during a flash freeze. I tried a few other diverters and put them to the test. The only one that stood is the RainReserve.

    The clean-flo diverter is by far the best diverter available on the market today. All aluminum water diverter with built in debris trap, and removable basket.
