The first problem was that this overflow barrel only filled when the water in other barrels got to a level higher than the overflow barrel. That's not a huge deal, but when it rains hard the barrels fill fast. The water then goes out the overflow on the barrel and doesn't make its way into the overflow barrel. This is due to pipe sizes. The tubing going from the main rain barrel to the overflow rain barrel is only 1/2". Water moves rather slowly through it. The overflow on the main rain barrel is 3/4".
The second issue is getting water out of the overflow barrel. The hose bib is 12" up from the bottom. That meant that there was a foot of water in there that I couldn't get out. It was unusable. This also made moving the barrel out from under the deck very difficult. (I like to check it once a year to make sure nothing is growing inside.)
