RainHarvesting Post Wall Mounted First Flush
Product Description:

The benefit of one larger unit is that it can be easier to maintain than a series of smaller diverters installed at each downpipe.

The first flush of water from the roof can contain amounts of bacteria from decomposed insects, bird and animal droppings and concentrated tannic acid. It may also contain pollen, water borne heavy metals and chemical residues, all of which are undesirable elements to have in a water storage system. Rain Harvesting's range of First Flush Water Diverters (or Roof Washers) capture the first most contaminated rainwater from the roof and gutters, automatically diverting the subsequent cleaner rainwater to the storage tank.

Diverter end caps contain 6.52 gallons.


Requires six sections of 4" PVC pipe which can be purchased online or at a local plumbing supply.



Product Improvements from Previous Design:


The Chamber for RainHarvest Post Wall Mounted First Flush

 

  • No More Bulky 12" Pipe

Easily divert large volumes of first flush with the Delta High Volume Chamber. Utilizing six four inch pipes to create the diversion chamber, the Delta’s revolutionary design makes installation a breeze.

 



The Ball Seat for RainHarvest Post Wall Mounted First Flush

 




  • Integrated Ball and Seat

The new unique design ensures that the first flush ball remains close to the seat, even in high flow events, making certain that the diverter seals as soon as the chamber is full. This means no more lost balls, when cleaning your outlet!

 



Drip Rate for RainHarvest Post Wall Mounted First Flush

 

  • Divert Larger Volumes

By allowing you to determine the frequency of first flush, the Advanced Release Valve ensures that the Delta’s first flush diversion is optimized. The transparent, rapid release exit funnel reduces build up and blockages while allowing for easy visual inspection.

 



Diversion Recommendations for the Roof

Minimal Pollution: divert 0.0125 gallons per square foot of roof area
Open field, no trees, no bird droppings, clean environment

Substantial Pollution: divert 0.05 gallons per square foot of roof area
Leaves and debris, bird droppings, various animal matter, e.g. dead insects, lizards, etc.


Example for a minimal polluted roof of 1,000 square feet:
1000 square feet X 0.0125 = 12.5 gallons to be diverted

Example for a heavily polluted roof of 1000 square feet:
1000 square feet X 0.05 = 50 gallons to be diverted
