"Brad came by to inspect our very old water softener that had stopped working. He determined it needed to be replaced and had a new one installed for us the following Monday. He was very informative and didnâ t charge us an arm and a leg. I highly recommend Maineâ s Best Water Treatment."

"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

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

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.

Softener systems extend appliance life spans, improve skin and hair health, and reduce pipe buildup by removing minerals like calcium and magnesium.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

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.
