Rain Harvesting WDPW110 First Flush Diverter Kit – Post/Wall Mount

Targeted First Flush Protection for Compact Rainwater Systems

The Rain Harvesting WDPW110 First Flush Diverter Kit is purpose-built for wall or post-mounted installations, making it ideal for small residential systems, sheds, or outbuildings. This compact yet effective diverter removes the initial dirty runoff from your roof before it enters your tank, significantly improving water quality with a sleek, space-saving design.

A high volume first flush diverter, designed specifically for mounting on a wall or any vertical structure. The unique manifold design uses standard 100mm or 4 in. pipe to create a high capacity storage and diversion chamber for your first flush. Using these smaller pipe sizes makes it easier to source pipe and assemble the system, when compared to using large diameter pipe on traditional high volume diverters.

Highlights

• Divert large volumes of water, easily - easily divert large volumes of water with delta's unique manifold design which only requires you to use smaller diameter pipe
• Ultimate first flush control - by setting the regularity of your first flush diversion, you can optimize how often your first flush diverter drains
• Catch-all tee improves clean water yield
• Easy maintenance - the catch-all tee ensures no water skips across the tee until the first flush of water is complete - which means you only capture the best quality water
• Just add pipe - the first flush delta in-ground comes with all fittings you need to set the system up just add the pipe to create the storage chamber

Commercial screened rain heads prevent leaves and debris from blocking downspouts and entering your rainwater tank. Rain heads are ideally installed on each downpipe as they protect the building and improve your tank's water quality. 6 inch (150 mm) outlet size.

The Rusco 2” Spin-Down Sediment Filter – 150 Micron/100 Mesh is built for high-volume water filtration, delivering dependable performance in agricultural, industrial, and large residential systems. With a 150-micron (100 mesh) polyester screen, this filter effectively removes medium to large sediment particles like sand, grit, and silt—protecting your pumps, valves, and downstream filters.

Designed for easy maintenance, the spin-down action forces sediment to settle at the bottom of the filter housing, where it can be quickly flushed out via the bottom valve—no disassembly required. The clear, impact-resistant housing makes it easy to monitor buildup, and the 2-inch NPT connections handle higher flow rates with minimal pressure drop.

The Rusco 1-100-ST-F Sediment Trapper Filter – 1” 100 Mesh (150 Micron) is specifically built to handle heavy sediment loads in a wide range of water filtration setups. Unlike standard spin-down filters, the Sediment Trapper features a larger debris collection chamber that traps more sediment, reducing the need for frequent flushing.

With a reusable polyester screen rated at 100 mesh (150 micron), this filter is ideal for well water, irrigation systems, and pre-filtration for residential or light commercial water systems. The transparent housing offers a clear view of trapped sediment, while the bottom flush valve enables fast cleaning without removing the unit from the plumbing.

The Ein Tahl / Rain Tal 1” Disc Sediment Filter with 5 Micron (3000 Mesh) filtration delivers ultra-fine sediment removal for water systems where precision matters. Designed for rainwater harvesting, drip irrigation, residential, and light commercial applications, this filter protects pumps, valves, and appliances from clogging due to fine sand, rust, and particulate.

Unlike standard mesh or cartridge filters, this unit uses stacked disc technology, providing a high surface area for filtration with improved dirt-holding capacity. The manual flush valve at the base allows for quick, tool-free cleaning—making it reusable and cost-effective over time.

The #20 Big Blue GAC Carbon Filter Cartridge is a granular activated carbon (GAC) filter designed for whole house water filtration. Built to fit any standard 20” x 4.5” Big Blue housing, this cartridge effectively reduces chlorine, unpleasant tastes, and odors, delivering cleaner, fresher water to every outlet in the building.

This filter uses impregnated coconut shell carbon, known for its strong adsorption capabilities and chlorine reduction performance. While not NSF 53 certified, it offers reliable general-purpose water improvement for residential, irrigation, or light commercial applications.

The Pentek HFPP-PR20 Big Blue #20 Filter Housing is a high-flow, heavy-duty housing built to accommodate 20” x 4.5” Big Blue filter cartridges for whole-house and commercial water filtration.

The Rusco Spin-Down Sediment Filter – 1½” 150 Micron/100 Mesh is a reliable, reusable filtration solution for medium-to-large water systems. Designed to capture sediment, sand, and dirt before they enter plumbing lines, this filter helps extend the life of pumps, appliances, and downstream filtration.

With its 150-micron (100 mesh) polyester screen, this model is ideal for well water, irrigation systems, and whole-house filtration where flow rates are higher than standard residential setups. The transparent housing makes visual inspections simple, and the flush valve allows for easy cleaning without disassembly.

The 3" First Flush Device (WDS99) is a vital component of any rainwater harvesting system, designed to divert the first runoff from your roof, which typically contains the highest concentration of dirt, dust, bird droppings, and debris. By isolating this “first flush,” the device protects your tank water quality and reduces sediment buildup.

This diverter is installed at the bottom of a standard 3” vertical downpipe (pipe supplied by others). As rain begins to fall, the device fills with the initial dirty water. Once full, cleaner water is allowed to continue into the storage tank. The unit can be manually flushed as needed between rain events.

Downspout First Flush Water Diverters improve water quality and reduce tank/cistern maintenance by preventing the first flush of water, which may contain roof contaminants, from entering the tank/cistern. They help ensure cleaner water is available for use, which protects rainwater pumps and internal household appliances such as clothes washing machines, toilets, hot water systems, etc.

Downspout First Flush Diverters, such as the 3" kits, are installed at each downspout that supplies water to the tank/cistern. They utilize a dependable ball and seat system - a simple automatic system that does not rely on mechanical parts or manual intervention. As the water level rises in the diverter chamber, the ball floats, and once the chamber is full, the ball rests on a seat inside the diverter chamber preventing any further water entering the diverter. The subsequent flow of water is then automatically directed along the pipe system to the tank/cistern. This kit does not include the 3" pipe.

Features and Benefits

• Prevents sediment, bird droppings, spiders, insects, mosquito eggs and debris from entering the rainwater tank/cistern.
• Improves water quality, protects pumps and internal appliances.
• Ideal to use in conjunction with a rain head.
• Easy installation, just add pipe and glue.
• No mechanical parts.
• Low maintenance requirements
