A softener that has just been installed, moved, or reconnected after a repair is still settling in. Early checks help you catch small problems before they grow, and they give you a baseline to compare against later. Public water reports describe the tap water in O'Fallon as hard, so the change from hard to softened water at the kitchen tap is usually easy to notice once the unit is working as it should.

Checks on the first day

  • Confirm the bypass valve is in the service position so water is passing through the softener, and write down the position you found it in.
  • Check the hardness setting on the control head against the paperwork or the note left by whoever set it up. Write the setting in your log.
  • Look at the brine tank. Salt should be covering the water, and the water level should sit below the salt.
  • Confirm the drain line is secured to a standpipe or drain and that it is not kinked or resting in standing water.
  • Look at every connection on the inlet and outlet sides for drips, damp spots, or loose fittings.

Checks during the first week

Over the first week, watch the unit go through at least one regeneration cycle. Listen for the normal sounds of valve movement and water flow, and note anything unusual, such as a long hiss, repeated clicking, or water running at the drain when it should have stopped.

Run a cold tap and a hot tap in the kitchen, and a bathroom tap too. Pay attention to how the water feels on your hands and how it runs through the faucet. Softened water often feels slippery, and that feel is a normal change. A strong salty taste is not normal and should be looked into, so note it if you notice it.

Check the water pressure at a few fixtures. A large drop in flow at several taps at once can point to a valve or bypass setting problem, so compare it with how the house ran before the work was done.

Spot checks with a home test kit

A basic home hardness test kit gives a quick reading you can repeat. Test the same tap, at roughly the same time of day, each time you check. Test once before the softener is in service if you can, then test again after the first week and again after the first month. Note the readings in your log along with the date and the tap you used. A reading that stays hard after the unit has been running properly is worth raising with whoever set up or serviced the unit.

Keep a simple start-up log

A short log saves guessing later. For each entry, write the date, the hardness setting, the salt level, any sounds or changes you noticed, and any test readings. Add a line whenever you add salt or see something unusual. If you ever need service, this record helps the technician see what changed and when.

When to call for help

Contact the company that installed or last serviced your unit if you see any of these signs:

  • Water running continuously from the drain line when no regeneration is expected.
  • Water sitting in the brine tank at or above the salt level.
  • A control display showing an error message or a blank screen.
  • Hard water still reaching the taps after the unit has run through several cycles.
  • Leaks at the valve, the bypass, or any fitting.

Do not open or adjust internal valve parts yourself during the first weeks unless the paperwork or manufacturer instructions tell you how to do it safely. Turn off the power and water supply before working on any connection.

Where your well fits in

If your home is on a private well instead of public water, the start-up checks above still apply, but test the raw well water before the softener is in service as well. Iron, manganese, and bacteria can change how a softener performs and how the water looks, so a baseline from the untreated water helps you tell what the softener is doing and what the source water is bringing in.
