The answer to 'water softener making gurgling noise' is that a gurgling sound from a water softener is often caused by air being trapped in the system. This can happen due to a blockage, low water pressure, or issues with the softener's internal components.
Some common causes of a gurgling water softener include: a clogged brine line, a problem with the softener's control valve, low water flow, or a stuck float. The gurgling sound may be accompanied by low water pressure or other issues. In most cases, this is a sign that the softener needs maintenance or repair.
