What are the Sounds of Water Leaks?
Water leaks in underground, pressurized pipes may make many different sounds:
"Hiss" or "Whoosh" from pipe vibration and orifice pressure reduction
"Splashing" or "Babbling Brook" sounds from water flowing around the pipe
Rapid "beating/thumping" sounds from water spray striking the wall of the soil cavity
Small "clinking" sounds of stones and pebbles bouncing off the pipe
The "Hiss" or "Whoosh" sound, which often sounds like constant static noise, is the only one which is always present for leaks in pipes with 30 psi or higher water pressure. The other sounds may or may not be present, and usually they are not as loud. So, we decide "Is there a leak?" by listening for the "Hiss" or "Whoosh."
