The big kids had a sleepover at my parents' the other night, so I set hubby to work setting up the rain barrels. Yes, the rains of June are over and we may not get more for a month, but better late than never!
It was a big pain because our old house has eavestroughs in a size and shape that is no longer available (we have this problem any time we try to do anything around the house - nothing is standard any more). So those nice downspout diverter kits you can get won't work here.
Our solution was a flexible downspout extender from Lee Valley. When the rain barrel is full, we simply unhook the flexi-pipe from the barrel and stick it into a drain pipe hidden behind, which extends out away from the house. Yes, we have to do it manually but it's probably only for one month a year (June, when we get the most rain).
Extra note: I purposely designed this fence so you can't see the ugly rainbarrel from inside the backyard!
