Your rain system will perform with the
highest efficiency if you do not leave out any of the steps or components. Starting with the clearest existing roof, section of roof or building another structure such as a pole barn in a less vegitated location will simplify the storing of relatively clear rainwater. |

and economical making it a good choice for most home
projects.The most direct and cost effective set-up is a long straight seamless-guttered eave with a single outlet/lead-in connected to a vertically mounted roof wash pipe.A wash pipe is a simple device that collects debris in the lower section as rainwater filters passively through a built-in stainless steel screen in the top. The debris is in turn flushed through a valve or clean-out at the bottom and the screen cleaned via an adjacent access. Connection from the wash pipe to the storage tank can be made directly into the tank |

top or tied into a pipe
manifold using attached risers.
Constructing a pipe manifold is similar to setting up a syphon.You must mount each wash pipe/riser 18 inches or more higher than the tank fill level.This difference in elevation creates passive lifting in each riser that pushes the rainwater through the manifold to the lower level of the storage tank input. |

The SDR-35 grade of 4-inch
PVC pipe and fittings is the industry standard for residential rainwater drainage. SDR-35 is lightweight, durable |
