FIRST FLUSH & LEAF TRAP COMBO KIT
The combo includes one First Flush Kit and one Leaf Trap.
The “First Flush” rainwater diverter kit is designed to divert any small or dissolved pollutants from your roof and gutters into a separate pipe chamber to ensure flushing of your roof and gutters, protecting your harvested water source from being polluted.
When the first rain falls, water slowly builds up in the first flush system before it exits through the side-pipe to your water tank or reservoir. The first flush of water from the roof can contain amounts of bacteria from decomposed insects, lizards, bird and animal droppings and concentrated tannic acid. It may also contain sediments, water borne heavy metals and chemical residues, all of which are undesirable elements to have in a water storage system.
Leaf Traps (leaf catchers) will help with leaves and larger debris but can’t stop small bits like dust and bacteria. That is why it is recommended that you install a First Flush Diverter. We all know that prevention is better than cure and so it makes sense to stop the pollutants from entering your tank.
Designed with a removable lid, to effectively harvest rain water from household roofs. The modern designed leaf trap prevents leaves and debris carried along and are filtered through the fine screen mesh lid that also deflects mosquitoes and other insects from entering your water tank.
Tank maintenance is greatly reduced and the designed angle of the product means leaves and debris are simply blown away leaving little need for cleaning.
HOW IT WORKS:
The first flush device is installed along the gutter down pipe that will feed into your water tank. As the water level in the first flush diverter chamber (110mm pipe) rises, the ball floats and rises. Once the chamber is full, the ball rests on a seat inside the chamber preventing any further water entering the diverter. The subsequent flow of clean water is then automatically directed along the pipe system through the T piece into the rain water tank.
It is best to have one first flush diverter on each downpipe however a single unit can be placed close to the tank and perform a first flush for several downpipes. This will really depend on how big your roof catchment is and how clean you need the water to be.
The amount of water you need to first flush will depend on:
The amount of leaves and pollution on the roof (polluted areas need to be flushed more)
(You should always check the quality of the water in your tanks before drinking it).
The amount of water flushed is determined by the length of the 110mm PVC (flush) pipe attached to the first flush kit. The average is 850mm of 110mm PVC pipe will flush 50sqm of roof catchment area and a 450mm of 110mm pipe will give you an 4 litre flushing system. The 110mm pipe is not included in the DIY kit but is readily available at any hardware store.
After the rain, just drain the system through the valve, ready for the next rain. The bottom of the unit (end cap) can be screwed off to fully clean the unit occasionally. During periods of frequent rain intervals, it may not be necessary to drain the first flush device every time as the roof and gutters may already be clean but this is entirely dependent on the dust conditions and rain intervals.
First flush systems work best when a leaf catcher box is installed at the start of the down pipe. The leaf catcher box (available from us and sold separately) is fitted at the start of the down-pipe either directly on the underside of the roof gutter at the facia board, or to the wall. The device deflects leaves and debris away from the flow of rainwater.
