Many Wentzville homes that run a water softener still keep one cold tap that skips it. The usual reason is taste, though some households simply prefer the feel of their drinking water as it comes in. Setting up that tap is a plumbing job with a few checks first, and this guide walks through what to look at before you start.
Why a Wentzville Home Keeps a Hard Water Tap
Public water reports for Wentzville describe the tap water as very hard. Softening removes most of the hardness minerals, and many people notice the difference right away in coffee, tea, and cooking. Others don't mind at all, and some households are simply used to the way their water tastes. A split line is a matter of preference, not a repair.
Softened water is not the same as unsoftened water in every respect. Softening replaces some hardness minerals with another mineral, so a homeowner who watches the sodium in their drinking water should ask a water test lab or their clinician what makes sense for their household. A lab report tells you what is actually in your water, which is more useful than guessing.
Where the Split Usually Goes
Most homeowners pick the kitchen cold tap because it is the one used most for drinking and cooking. Some also run a branch to a refrigerator dispenser or ice feed. Decide on the location before you open any pipe. Look at where the line is easiest to reach and whether it sits ahead of or behind the softener.
Checks Before You Start
- Find the softener's inlet and outlet lines and confirm which side feeds the kitchen cold line.
- Check whether the softener already has a bypass valve. Many do, and it can change the approach.
- Look at the existing pipe material and joints near the kitchen sink.
- Confirm the shutoff valves for the whole house and for the sink before you cut anything.
- Decide whether a refrigerator line will also be unsoftened, since it may share the same branch.
Running the Split Line
A common setup takes cold water from the main line ahead of the softener and sends it to the kitchen tap through a separate branch. The hot line and the rest of the house stay on softened water. Plan the work for a time when you can leave the water off for a while, and keep a bucket and towels close by.
- Shut off the water supply to the house at the main valve.
- Open the taps to drain the remaining pressure.
- Cut or tap the pipe where the new branch will start, ahead of the softener.
- Install a tee or manifold fitting and run new pipe to the kitchen cold tap.
- Turn the water back on slowly and check every joint for leaks before closing the cabinet.
Well Water Is a Different Case
On a private well near Wentzville, the split line needs more thought. Well water can carry iron, sulfur, hardness, or other constituents that a softener alone does not address. Private wells are unregulated, so there is no utility report to rely on. Before you send unsoftened well water to a drinking tap, have the well tested so you know what is in it and whether a filter is needed ahead of that tap.
Testing and Labeling the Result
Once the line is in, compare water from the softened and unsoftened outlets with a basic hardness test kit. Write down the date and the location of each tap. A simple note taped inside the cabinet door is enough, and it helps anyone who works on the plumbing later.
When to Call a Plumber
If you aren't comfortable cutting into a pressurized line, a licensed plumber can run the branch for you. Ask them to show you where the split begins and how they will keep the softener's operation unchanged. Get the work written down with the date, and keep that record with your other home water documents.
