For Filtering Rainwater, We Use A Custom 3" PVC Pipe With A Filter
Using 3" PVC pipe and fittings to construct your own rainwater filtering device is much cheaper than purchasing the name brand filtering systems like the Leaf Filter and First Flush Diverter.
The problem we found with the Leaf Filter and First Flush Diverter is the cost firstmost and the fact that both systems waste precious water due to spillage and drainage issues where a 3" custom tube with filter wastes no water for a lot less money.
After pricing and reviewing all available rainwater filter systems, we decided to build our own rainwater filter system, not so difficult.
Materials: One 10 foot 3" pipe at $20 can be cut to 10" lengths for 12 tubes, one 3" x 3" flexible coupling at $7 for each tube as needed, and one IBC filter at $3 for each tube as needed, can make up to 12 tube filters. The filters fit nicely into the 3" tubes.
Just cut the 3" pipe length to fit the filter (8"-10") and join the pipe with the flexible coupling where you can remove the coupling periodically to clean and rinse the filter. You can stack the tubes to double filter if you like.
Place the tube filter at a height most easy to access for periodic inspection and cleaning.
If you prefer 2" pvc pipe opposed to 3" pvc pipe, connect a 3" to 2" pvc adpater after the 3" pvc filtering system.
Both Homedepot and Lowes offer all of the PVC pipes and fittings. The filters are available at Amazon.
