If the water that comes through your pipes is "hard", meaning that it contains chlorine, iron, and other minerals, you should consider a water softener. A great choice is a shower water softening system that is where you come into contact with the most water.
A water softening system uses neutralizing ions in sodium to remove the minerals that can turn your hair green, irritate your skin, and create a crusty buildup on pipes and fixtures. There are 2 options for installing a shower water softener. Choose the one that fits your level of DIY skills.
Step 1 - Installing a Shower Filter
If you are not sure about installing an entire water softening system, and you just want to filter the water that comes from your shower, you can simply install a filter directly onto the showerhead. It is a very simple way to have a shower water softener. Even if you are not a seasoned DIY enthusiast, you will more than likely be able to install the filters. You can also buy a new shower head with a built-in water filter.
Step 2 - Turn Off the Water
Turn off the water so that you can fit the water softening system onto your water supply.
Step 3 - Where to Attach the System
If you want soft water throughout your home, locate the spot where the water supply enters the house. If you are only interested in a shower water softener, you can connect the system to your water heater, and the benefits will reach your shower.
Step 4 - How to Hook it Up
On the back of the water softening system, there should be very clearly marked ports that say "in" and "out". Make sure you attach the "in" port where the water enters the house. If you accidentally cross the connections, then the shower water softener will not work properly. The system will say that it is on and working, but your water will not have the benefit of the softener.
Step 5 - Connect the Drain Line
Water softening systems also come with a drain line. If you don't hook it up to your home's drain, you'll end up with a flood. Locate your house's drain and make sure you connect the softener system's drain line to it.
Some water softening systems have 2 tanks. 1 is filled with sodium water, which is used to neutralize the iron, chlorine, and balance the acid. If your system has a second tank, then you must be sure to connect it with the first piece of equipment.
