A misting system is a simple way of cooling you down on scorching hot summer days. The system uses a curtain of ultra-fine droplets to lower the temperature as they evaporate. Rather than soaking you, it should feel like the blissful cool of a misty morning.

To set one up, select a misting kit in the required length. Along with the pipe, connectors and tiny brass jets, the kit includes a debris filter and a brass auto-drain valve to prevent dripping when it’s turned off. Buy a tube cutter and tap timer if your kit doesn’t have them.

Pro tip: Before installing, work out how the pipe will run from the tap and along the rafters or beams. Plan for the jets to be positioned away from furniture and open windows or doors.

Safety tip: Always wear the appropriate safety equipment (eye protection, for example) and always follow the instructions for the product or equipment.


1Attach the misting filter

Screw the misting filter directly to the base of the tap timer. Next, screw this assembly directly onto the tap using the supplied universal tap adaptor. Insert one end of the pipe into the filter, tightening the attachment.

Tip: We chose a timer that connects to Wi-Fi so the system can be operated via smartphone.

2Run the pipe to the wall and install a tee connector

From the tap assembly, run the pipe to the wall. Use the tube cutter to cut it cleanly and install a tee connector for the auto-drain valve.

Note: The valve is installed lower than the jets so that when it's turned off, excess water drains down down the pipe and out of the valve.

3Mark and fit the pipe

Before installing the connectors, unscrew the brass jets and set them aside on a clean surface.

Tip: To fit a connector, push it over the pipe by 10mm, holding it straight and twisting slightly. Once the pipe is fitted, it can't be removed, so use tape as a marker to avoid pushing it in too far.

4Assemble the system

Use a sturdy step ladder to join up the rest of the system without securing it to the wall, rafter or beam, using clamps or tape to hold it in place. Space the connectors 600mm-1000mm apart, cutting pipe to fit between them and using elbows around corners. Finish with a misting elbow at the end.

5Flush the system

Unscrew the brass auto-drain valve and then turn on the tap to flush the system. Leave the water running for a few minutes to ensure any debris are removed. This will avoid clogging the tiny holes of the brass jets.

Tip: Place the connected assembly in location where the water from the flush will drain away from the house.

6Secure the pipe assembly

Use the supplied pipe clips to attach the pipe assembly to the wall, rafter or beam, positioning them 50mm on either side of all connectors, including the auto-drain valve.

Tip: The clips come with masonry nails that can be hammered into timber or brickwork, but avoid attaching them to metal.

7Refit the valve and brass jets 

Reinstall the auto-drain valve and the brass jets in the connectors, twisting them on firmly. Set the tap timer to begin misting.

Tip: The system is not designed to run constantly, so program it to come on when you’re outside or during the hottest part of the day.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
