Leaf Eater Advanced RHAD100 Rain Harvesting Head for 3" and 4" Downspouts — 95%+ Capture, 1000µ Stainless Screen

The Leaf Eater Advanced RHAD100 is a dual-size rain head that fits either 3" or 4" downspouts to capture debris-free rainwater with 95%+ efficiency.

The RHAD100 is the updated Leaf Eater Advanced rain head that replaces the older single-size models and includes adapters to work on both 3-inch and 4-inch downspouts. Designed for rooftop rain harvesting, it uses a 1000-micron stainless screen and a self-cleaning geometry to direct clean water into storage while diverting leaves and large debris. This description explains how it fits, how it performs, and who benefits most from this model.

How does the RHAD100 fit 3" and 4" downspouts?

The RHAD100 ships with two adapter collars that slide into the body so you can install it on standard 3" or 4" downspouts without custom plumbing. Installation is simple — remove the existing downspout elbow, place the chosen adapter, and secure with the included clamps or screws.

• Includes adapters for both common downspout sizes
• Fits directly to elbow or vertical downspout ends
• Minimal cutting or modification required

What makes its capture efficiency so high?

Leaf Eater Advanced engineered the RHAD100 to achieve 95%+ capture efficiency by combining a 1000-micron screen with flow-splitting geometry that separates debris before water enters storage. The screen size balances clog resistance with fine-particle capture for cleaner collected water.

• 1000-micron stainless screen for reliable filtering
• Flow-diverting internal design reduces splashing and sediment entry
• Self-cleaning action reduces maintenance needs

How easy is maintenance and cleaning?

Routine upkeep is quick because the RHAD100 is self-cleaning and designed for easy access. Most users need only inspect and rinse the screen seasonally or after heavy debris events; no specialized tools are required.

• Tool-free top access to remove and rinse the screen
• Self-cleaning geometry sends leaves to downspout overflow
• Durable materials resist corrosion and weathering

What installation and performance details should I expect?

The rain head performs well on residential and small commercial roofs and integrates with common rain-harvest systems and cistern inlets. It handles typical roof flow rates while diverting twigs, leaves, and larger debris away from storage tanks.

• Works with gutter systems feeding 3" or 4" downspouts
• Compatible with gravity-fed and pump-assisted harvest setups
• Compact footprint mounts near gutter exit for unobtrusive installation

Who is this for? Homeowners, small-farm operators, landscape professionals, and anyone installing or upgrading a domestic rain-harvesting system will benefit from the RHAD100. It is ideal if you want a low-maintenance, high-capture rainhead that adapts to common downspout sizes without custom plumbing. Avoiding frequent tank contamination and minimizing screen maintenance makes this model a practical choice for year-round collection in temperate and debris-prone environments.
