ProH2O Water Leak Detection Application Guide

SENSOR CABLE INSTALLATION

Leak detection around pipes

ProH2O  detection  cable  can  be  used  to  provide  early  warning  of  leaks  from  pipework,  valves  and  similar 
equipment.

  It  is  important  to  maintain  the  surface  contact  between  the  pipe  and  detection  cable.  A 

maximum  spacing  of  150mm  (6")  is  recommended  between  cable  ties  when  the  detection  cable  is 
attached  to  a  pipe. 

Adding  lagging  around  the  pipe  over  the  detection  cable  further  improves  the  chance  of 

detecting  a  leak. The  effectiveness  of  the  detection  cable  when  attached  underneath  a  pipe  is  dependant  on 
many variables however the most important differerence between leak detection on a pipe and laying the cable 
on a surface is that a continuous flow of water must be present on the pipe to trigger an alarm.
