He took the time to answer all our questions, made sure everything was set up perfectly, and left the workspace spotless. You can tell he takes pride in his work. We?re beyond happy with the results and grateful for the excellent service"

"They did a excellent job. I had 3 plumbing companies out to try and figure out why I had no hot water in my home but premier did. The first company said I had a faulty water heater. Heater was only 7 years old. They replaced it and told me to wait 2 hours and still no hot water. They came back out and said it was a defective unit. They replaced it and still same issue. I hired another company and they couldnt figure it out. Here comes the professionals. Premier checked everything and found I had a faulty shower cartridge. The cold was mixing into the hot. Easy fix and we had hot water again. Thanks again premier plumbing. Ask for the tech Chriss. He is awesome."

Water Softeners FAQs, answered by experts

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

A water softener is a worthwhile investment if you live in an area with hard water. While hard water is safe to drink, it contains minerals like calcium and magnesium that can cause significant problems over time. These minerals build up inside pipes, reducing water flow and eventually corroding the plumbing system, which can lead to leaks and a shortened lifespan. Hard water also damages fixtures and appliances, potentially resulting in costly repairs. Additionally, it makes soaps and detergents less effective, meaning you'll use more product to get things clean. By installing a water softener, you can prevent these issues. The initial investment is often recouped through long-term savings, including lower energy bills, reduced appliance and plumbing maintenance, and spending less on soap and cleaning supplies. Other benefits include cleaner linens, dishes, and clothing, as well as softer water that is gentler on your skin and hair. In some areas, a water softener can also increase your home's value, making it a valuable long-term investment.

Drinking hard water is not known to have any negative health impacts. Using hard water can lead to dry skin and hair, and the minerals in hard water can build up in pipes, faucets, and appliances. Hard water is more of a threat to your plumbing than it is to your health.

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.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.
