The earthminded rainwater catchment filter is suitable and reliable and fits well with your daily purpose. This is a great rain water collection kit. The patented flexifit diverter installs easily by drilling a single hole into any standard 3 ” x 4 ” rectangular downspout. The diverter ( inside the downspout) will trap leaves and debris. The design of the baffle is pretty brilliant.

The diverter is very simple to install, just take care to drill the hole at the right height and centered on the downspout. It is perfectly and so far the hose connector is leak free. The included hole saws are perfect for the job. The flexible hose will extend or collapse as needed, and it easily connects/disconnected from the barrel as needed.

Why We Like This:
  • Everything you need including drill sets, hosing and rain gutter insert
  • Nice kit, affordable kit for collect rain water
  • Improve the filling efficiency of the diverter
  • Great, easy to install, effective rain diverter
