The Brett Martin Rainwater Diverter (BR222) is a simple and very effective, yet low cost device used to direct rainwater run off from your domestic rainwater system. Simply inserted into a downpipe a rainwater diverter will provide free clean water and will save anyone on metered water money, and more importantly will save water during water-shortages and hosepipe bans. The system works by collecting and filtering rainwater from any domestic rainwater system including Brett Martin's 106mm Prostyle, 112mm Roundstyle, 114mm Squarestyle and 115mm Deepstyle with any compatible 68mm round and 65mm square standard downpipe systems. Easy to fit the rainwater diverter is connected to the downpipe to the top side of the water butt, some water butts will require a hole drilling in order to take the feed from the diverter. When the butt is full, the design allows excess water to bypass the diverter outlet and continue down the pipe to prevent overflow. The supplied rainwater can be used by simply branching off to a tap or hose connection for later use in the garden.
