First Flush Boost 100mm

An all-inclusive First First Diverter kit to keep dirty water away from your tank. With most First Flush Diverters, you are required to create a diversion chamber with a length of PVC pipe. The First Flush Boost already includes a 20L / 5gal chamber so you don't need to create your own chamber. If you need to divert more water, the Expansion Kit is available, which is specially designed for the First Flush Boost to increase your diversion volume by 20L (5gal) at a time. You can install up to two of them, to bring your total diversion volume to 40L (10gal) or 60L (15gal). Installation and Specification Guide
