"Justin was professional and knew exactly what I needed to fix my existing water heater without trying to upsell me on a much more expensive tankless water heater. He had the relief valve and expansion tank in his truck and was able to install everything without issue. I would recommend hiring them for your plumbing needs!"

Water Softeners questions, answered by experts

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.

The most accurate way to determine whether you have hard water is to purchase a water test kit from a hardware store or send a tap water sample to a lab. But there are some signs you can look out for without professional testing. For instance, if you're consistently dealing with mineral stains on your glassware, windows, and shower doors, you're likely to have hard water. Hard water can also make it harder to lather and rinse soap, so if you're struggling to work up a good lather in the shower, hard water might be the culprit.

Generally, it is safe to bathe in yellow water, as the color is often caused by iron, tannins, or rust, which won't harm your skin. Soap will still clean you effectively, though the water might leave stains. However, if the water has an unusual smell or you suspect contamination, avoid bathing and contact a plumber for an inspection. A professional can also help if you find bathing in yellow water problematic and want to determine how to get your water clear again.

You can decide whether you need a water softener or water filter based on how your bathing or laundry experience is. If you notice issues like limescale buildup, dry skin, or stains on dishes—all telltale signs of hard water—you'd likely benefit from a water softener. However, if your main concern is over chemicals or bacteria in your tap water filter, and not just comfort, a filter is a better option.

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.
