Rain Collector for Downpipe – Gravity Watering Adapter

Your downpipe already carries rainwater past the point where it could be most useful. This collector fits directly into the pipe run, taps that flow, and routes water to a raised tank — so you can water the garden by gravity alone, no pump required.

The idea is simple: instead of letting rain drain straight to the ground or catching it in a bucket at floor level, you intercept it mid-pipe and send it to a storage tank mounted as high as possible. That elevation becomes your water pressure. Gravity does the rest.

How it solves the problem

Standard gutter accessories are designed to drop water into a barrel on the ground. That works for storage, but getting that water back up to where plants need it means lifting or pumping. This collector works differently — it captures water at height and preserves the hydrostatic pressure of the full pipe column. Your storage tank stays elevated, your hose pressure stays usable.

• Replaces a 10 cm section of your existing downpipe
• Built-in leaf filter keeps debris out of your hose connection while letting it continue down the pipe
• Threaded hose connector routes water directly to your tank or irrigation line
• Works with common downpipe diameters — check the variant listing for your size

The setup

Installation means cutting a short section of your downpipe and slotting this collector in its place. The collector seats into both pipe ends, the leaf filter faces the flow, and your hose attaches at the side outlet. Position it as high on the pipe run as practical — the higher the collector, the more pressure head you get at the outlet.

It is a straightforward job that most people complete in under an hour with basic tools. Once it is in place, every rain event fills your raised tank automatically.

Where it shines

Best suited for garden irrigation setups, allotment plots, or anyone who wants off-grid watering without running power to a pump. Particularly effective when combined with a wall-mounted or elevated IBC tank.
