I am so excited that Craig and I got our first rain barrel in last night just in time for the rain. I was surprised to see how fast it was to install. This is one of the largest rain barrels around. We are going to start with 5 rain barrels- 1 for each down spout. However, there was only a smattering of rain last night and when I checked this morning, it was 1/2 full! My advice to everyone considering a rain barrel is to get the largest one that you can find and also get one with a wide overflow ( see the hose on the left side of the barrel). 1 inch of rain can give 600 gallons of water off of an average roof size! If we had had a substantial rainfall, the regular overflow would not have been able to handle the runoff once the barrel was full and it would have overflowed out the top of the barrel. Having said that, if I were to connect several rain barrels, then only the one on the end of the line would require a large overflow. We have directed the overflow hose away from our house and to our flower garden. Somehow I feel that my rain barrels are going to multiply once I see how much rain I can harvest! Not only does it save $$$, & the environment but my garden will do much better with rain water than tap water coming from a garden hose. I will keep posting on my rain barrel experience!
