We have a number of rain barrels and 275gal totes that we have acquired in various ways. We needed a way to filter the water coming from the rain gutters before storing it in the totes (we figured they would be hard to clean out later). I also wanted a way to divert water into multiple barrels so that when it rains we can fill multiple containers in parallel. After evaluating many different designs i settled on a two 2.5 gal bucket system with 1/2 inch hoses for the divert-er.
Four 1/2" barbed couplings.
50' roll of 1/2" tubing for drip systems.
The whole thing cost about $25.
