• The specially designed, patented First Flush Plus Tee forces fast-flowing water into the diversion chamber preventing the problem of dirty water skipping over the traditional T-junction gap during heavy rainfall
• Reduce sediment build-up in your tank and sediment load on your post-tank pumps and filtration systems
• Automatic reset valve drains after rainfall events

Our first flush diverters play an essential role in protecting your
rainwater quality. By isolating the first flush of contaminant-laden
water from your roof, they keep organic and inorganic fine particles
out of the rainwater you harvest.
