A water softener makes a hiss during regeneration and an occasional hum, but a loud or constant noise points to a problem. Air, a stuck valve, or a pump issue are the usual causes.
The hiss
A hiss during regeneration is normal — it is the brine being drawn and the valve cycling. hard water is common across the region, and older neighborhoods still have galvanized supply lines In Franklin, a quiet hiss at night is the unit working.
The hum
A hum from the motor or the valve during regeneration is the mechanism running, and it should stop when the cycle ends.
The air
Air in the system makes the softener sputter or knock, and purging the air clears it.
The stuck
A valve that clicks or grinds continuously can be stuck or failing, and servicing the head fixes it.
