“I haven't written any report but I've been monitoring the ant-prone hydrants for a couple of years where the Retroguard boot was already installed. Once it was installed, I never saw any problem with ants in that hydrant again.”
Sagar Khadka, Asset Management Engineer, ACTEW (Icon Water)This hydrant was looked after by a Community Fire Unit (CFU), who used to call three to four times a year about ant build-up. Since a Hydraguard was installed as a trial on 7 March 2011, there has been no repeat ant dirt problem. The photo below, taken exactly 10 years later, is the same fitting.
