I completed a water softener installation today, implementing a dual-tank system for continuous soft water availability. After shutting off the main water supply, I installed a new drain line with proper air gap, connected the brine tank with reinforced tubing, and mounted the control valve. The water softener installation required careful programming of regeneration cycles based on the home's water hardness levels and usage patterns. I also installed a pre-filter system to protect the softener resin, added the initial salt load, and performed multiple regeneration cycles to properly condition the system. Before finishing, I tested the water hardness at multiple outlets to confirm proper operation.
