What’s a RapidTest stick?
This one-minute test determines whether any damaging magnetite (black sludge) is present in a hydronic system. Magnetite is a result of oxidation inside an untreated hydronic system and causes reduced system efficiencies and component failure.
- Take a small sample of system water (in a bucket for example)
- Dip and swirl the stick in the water sample for roughly 10 seconds
- Remove and check the colour of the stick.
- Follow the recommendations below:
BLACK/GREY: This is indicative of existing corrosion
ORANGE/BROWN: This is indicative of active corrosionPlease see ADEY’s Best Practice® blog HERE for steps on how to retore/treat systems.
