Now the new drain pipes are installed, it's time to buy a rain barrel also. But this one needs to be filled... Apperantly there are some very simpel ways to fill a barrel. The cheapest flow diverters cost about 10 euro and the more advanced around 35-50 euro.
So time to design my own.
-Automatic diverting flow when barrel is full.
-Leaf protector, so no need to clean the barrel.
-Integrated open/close tap, so during winter time the drainage water will not enter the barrel.
-2 parts only (1 needs some support)
-Connection to 70x2mm pipes.
-Connection to 1 inch barrel hose.
For changing the tap, the top part needs to rotate 30 degrees.
So the drain pipe above should not be connected too thight.
Total amount of fillament ~200 gr, so that's about 12 euro (colorfab HT), at least 3 times cheaper then the advanced commercial ones.
Finally printed a 2nd version. Took some iterations for getting that filament printing right..
Any way, it's working!!
