Easy Maintenance
Benefits
Divert Large volumes of water, easily
Standard large format First Flush Diverters require you to use large diameter pipe (eg, 300mm / 12"). It can be difficult to source in smaller lengths and can be expensive.
The Delta's unique manifold design uses lengths of 100mm or 4" pipe instead, so sourcing the pipe to make the chamber is easier. It means you can assemble your First Flush Diverter quicker, to get the job done.
Each 1 meter of length in the Delta = 73 L diversion.
Each 1 yard of length in the Delta = 17.5 gal diversion.
Benefits
Ultimate First Flush control
By setting the regularity of your first flush diversion, you can optimise how often your First Flush Diverter drains.
Do you want the best quality water possible? Set it to a regular reset interval of three days or less.
Do you need to maximise the volume of water your capture? Increase the reset interval to two weeks or more.
Want to start off with a great compromise of water quality and quantity? Try five days.
Benefits
Less maintenance and clogging
Traditional First Flush Diverter valves have a tendency to clog over time - they only have a tiny hole so it is inevitable. The release valve on the Delta First Flush includes a unique funnel design and a much larger draining hole, which means that water drains as it's supposed to and there is far less chance of the unit becoming clogged.
Benefits
Just add pipe
The First Flush Delta Commercial comes with all fittings you need to set the system up. Just add the pipe to create the storage chamber.
There are different kits available with different sized T-pieces and reducers, so choose the one for your needs. You can even buy the kit without them if it's more practical.
