First Flush Water Tank Filtration Devices

 

First flush devices are engineered to divert the first rainwater that flows from your roof to a chamber that slowly releases the dirty water over time, preventing the contaminated water from entering your water tank. The advantage of a first flush device is that the capacity can be infinitely variable (determined by the chamber length and diameter) so you can adapt it to suit the amount of water you want to divert when it first rains. But like anything else in your rainwater system it requires regular cleaning to ensure that the dirty water empties and it is ready for the next rain that comes along.
