Water Softening Equipment

Reasons for High Water Hardness in Softening Water Equipment
1. The O-ring seal at the multi-way valve's center tube is damaged
The issue often occurs during the initial debugging of a newly installed water softening unit, where the water output hardness exceeds the allowable limit. The cause is either the absence of chamfering on the upper part of the center tube or the lack of lubricant applied, which leads to the O-ring seal at the multi-way valve's center tube insertion point being damaged upon insertion. This results in hard water mixing, causing the output water hardness to exceed the standard. Solution: Replace the O-ring and apply lubricant during installation.
2. Softening resin aging failure
The issue usually occurs after two years of use in a softening water system, when the softening resin loses its activity and cannot be restored even through regeneration. Solution: Replace the resin.
3. Inability to absorb salt or short salt absorption time
The brine system of the soft water equipment is malfunctioning, or the incoming water pressure is too low (for equipment using a jet injector) which will cause this fault. Solution: Check if the jet injector is clogged, or if the brine pump is faulty, and increase the incoming water pressure (the appropriate pressure range is: 0.2-0.4 Mpa).
