Dear Shridhar , Honestly ...

Dear Shridhar ,

Honestly  their is no particular technology in the world which give us exact pin-point leak locations in plastic or non metallic pipes .

I have worked with SmartBall as well as acoustic correlatore too fails in plastic pipes , their is only either options are you use acoustic hydrophones or tracer gas (helium). 

But in helium you can't get the pin-point data & in cloudy conditions it is difficult to find leakages. My point of view tends to acoustic hydrophones which give good data in any pipes . You can use it with correlators , however plastic pipes are bad conductor of sound so hydrophone takes water is their medium to correlate not the pipe wall . 

Thanks,
