Dear Friend，
In my understanding, the HDPE you mentioned should be DN300 or below. The Sahara and Smart ball are not optional here (both of them only used for large DN pipe).
If the water pressure is above or equal 0.25 MPa, I suggest that you try to use cor-relator with two special sensors (hydrophone). On the condition that pipe length is less 100m between two sensors(accelerate type), normal cor-relator is also useful.
We have successful examples to pinpoint leakage point in PE pipe.
BR,

Thank you for your suggestions , we already tried hydrophones but results was not satisfactory , I was asking for lesser dia and pressure is also 12 m in network , planned to try LNC next week

Pressure 0.12MPa (12m water head) is too low. Just for your reference.
Gook luck!
