RL-SET-20
Low-pressure protection set
20 nozzles, 1 circuit, one water point
The same building block as the standard set, sized for a low-pressure supply: everything needed to run one circuit from a single outdoor tap, designed to reduce ignition vulnerability across your roof and perimeter.
One set covers one water point. It drives a single circuit of up to 20 nozzles over 20 m of tube, which is what a low-pressure domestic tap can supply without the last nozzle on the line going soft. Two circuits of 30 nozzles over 30 m would drop the pressure across the whole run.
The nozzles are bendable brass. That forgives an uneven roof edge during a DIY install, and it lets you aim each nozzle away from sight lines so the system disappears once it is up.
Every nozzle adjusts from a fine atomising mist to a water column by turning the tip: left for mist, right for jet. Mist helps pre-wet vulnerable exterior surfaces; a directed jet can reach a far edge or gutter from a discreet position.
Used as part of a complete EleHalo layout, this set helps suppress landed embers and low-intensity spot fires and adds an active layer to defensible space and home hardening.

Compatibility notes
- • Tubing is ordered separately — length depends entirely on your layout.
- • Needs one dedicated outdoor tap. Do not pair with a Y-type dual outlet — a low-pressure tap cannot feed two units.
- • For an average or high-pressure supply, order the standard protection set instead.
- • Works alongside the perimeter protection set on the same property, but each rail run needs its own circuit budget.
Installs on a regular 3/4" tap
No plumber and no permanent pipework. The system connects to an ordinary outdoor tap — the same one you use for your garden hose. Standard outdoor taps carry a 3/4" (G3/4) male thread, which is what the supplied tap connector is made for.
Many taps ship with a hose tip, nozzle or aerator screwed onto the end. In most cases you can simply unscrew that tip by hand (or with light pliers) to reveal the bare 3/4" thread. Wrap two or three turns of the included thread-sealing tape, screw the connector on hand-tight, and the tap keeps working normally for everyday use.
Smaller 1/2" taps, indoor mixer taps and washing-machine valves are covered by the included thread adapters. If your tap has an unusual or worn thread, the garden hose connector lets you feed the system from any standard hose fitting instead.
