A Doust Plumbing Product About Rainwatch Tel: (08) 9249 7039


Please note:

Provide a 150 mm relief over flow above the RainWatch Filter and have a minimum relief of 150 mm from the bottom of the gutter for a continual discharge making sure that no water can enter the building. Also ensure that the storm water line gradient to the rainwater tanks allows for no pooling of water or water traps as described as a WET SYSTEM by other manufactures.

Additional rainwater tanks can be interconnected from the first rainwater tank as shown at the base of the rainwater tank with a 25mm line. Naturally all the rainwater tanks inlets and outlet (usually one overflow outlet will suffice) should be level. (shown below.)

Installation below outlines not recommended installation.
