A standpipe on a hydrant is a direct connection to the public main, so it has to be used carefully. The assessment checks you know the rules for using them without contaminating the supply.
What standpipes and hydrants covers in the assessment
- Taking water from a hydrant needs an authorised standpipe fitted with a double check valve for backflow protection
- Keep the standpipe and hose clean
- Keep the hose end off the ground and out of puddles, tanks and ponds
- Unauthorised or dirty standpipe use can draw contamination back into the main
- Only use hydrants as authorised
- Report any problem or damage rather than carrying on
Where people slip up
Dropping the hose end in a puddle. Contaminated water can be siphoned back into the main.
