The First Flush Contractor Kit, Bushman part number 64331, has the parts to build a first flush diverter for a rainwater tank, without the PVC pipe, so installers can use pipe bought locally.
How it works
The diverter holds the first, dirtiest roof runoff in a chamber that seals once full, so the cleaner water that follows goes on to the tank. The held water drains out through a drip emitter with a threaded cleanout before the next storm. Hose off the filter every other storm.
Kit or connection kit
The First Flush Connection Kit, part 64329, includes the pipe. Size the chamber with our first flush diverter sizing guide.
