Purchased this to divert water from the gutter into a rain barrel without having to install an overflow valve. Worked like a charm. When it first rained after installation, it filled up a 55 gallon rain barrel to the top and then diverted the water back thru the downspout after the barrel was topped off. It is a very heavy duty white plastic. It can be painted if you wanted to. Follow the instructions when installing so you do not cut too much out of your gutter (just holding it up and measuring by the size will make you cut out more gutter than you need to). The hose it comes with is thick plastic and is folded. You will need to remove the creases from the hose or the water will not flow thru. A blowdryer to heat up the creases while you bend it will work. Also comes with a stopper to plug up the diverter during the winter months. We initially ordered just one, to make sure it actually worked. We are very happy and have ordered more. _______ I forgot to add that this worked great on our rain barrel systems, as we have a closed top with bung holes. We left one bung hole closed and put the end of the hose thru the larger bung hole. If you have an open top rain barrel then it will just keep filling up and flowing over. The way this system seems to work is by pressure. As your rain barrel fills up, water is forced back up the hose and down the downspout. If you have an open top rain barrel (no top or just a screen) then there is no way to generate the pressure to stop the flow of water into the barrel once filled. Also: these will fill up a 55 gal rain barrel pretty quickly, even with just a normal amount of rainfall.
