Your First Flush …CAN BE A DOOZY!


When harvesting rain, it is a good practice to allow the first gallons of rain water flush the roof, gutters, and collection pipe free of dirt and debris.  Here at Zinger Hardware we have compiled a few step by step pictures to help customers understand the first flush pipe and why it’s a DOOZY!

The first flush system mainly consists of three main components. The first is an intake trough and screen know as a leaf eater.  It allows fresh rainwater from the gutter can to empty through the screen into a pipe system.  The angle of the screen diverts large debris off and away from the pipe intake.

Secondly there is a 4″ PVC pipe mounted vertically on a column or wall that will hold the first few gallons of murky water.  The 4″ PVC pipe is fitted with a connection that will permit a coupling to be added that has a small screen and a drip nozzle.  The concept is the first rain will wash the debris off and the dirty water will be captured by the pipe.  The dirty water can then drip from the bottom of the pipe, until drained.  If it begins to rain again in a few hours the pipe will not have to be refilled saving you gallons of fresh rainwater.

The last component is a ball float that will rise up the 4″ PVC pipe tube and close the T-fitting, as shown, allowing the clean rainwater to flow across into the rain harvesting tank.

It is always important to remove the bottom coupling on a regular basis to remove the DOOZY of a pile of wet debris.  Remember to keep the ball in the pipe and not play catch with Phideaux!
