How old is that installation?
Butadiene rubber is pretty resilient but like anything has its limits. Frost heaving, settling, and seismic activity is the only thing that can think of that could cause it to tear and fail. If the weeps can be traced to the line itself going back to where the seal meets the line, tightening the clamps down with a nut driver is enough to stop it.
We're on wells up here and I like to see the lines at 36" depth or more, well below the frost line.
City water copper feeds also can transmit vibration from roads if your foundation is <50' from a roadway. Some communities that have lots of cut through traffic put in traffic humps and I pity anyone that has one in front of their home and lives close to the road!
In any case, those small water alarms are nice. Especially around the laundry sink!
