"The installation technician, Danny, showed up on time and was extremely professional and friendly. He installed a reverse osmosis system under the kitchen sink with a brushed nickel faucet beautifully mounted on our granite counter top, as well as a whole house water filter and softening system in the garage. His workmanship was terrific and the system works great, we couldn't be happier!"

"I had an excellent experience with Pro Bright Construction. They responded to my initial inquiry very quickly and were able to schedule the installation of a whole-home water flow restrictor on the main water intake that same day. The two professionals who completed the work were friendly, knowledgeable, and courteous. Although this was a significant installation, they finished the job in just a couple of hours and left the work area spotless. I was quoted a price by a large plumbing company that was nearly twice the amount I paid, so I also appreciate Pro Bright's very fair pricing. I'm left truly happy for their prompt response, professionalism, quality workmanship, and value. I will definitely contact Pro Bright Construction for any future plumbing needs and highly recommend them."

"The technician for Carini was very polite and professional. He performed the services and explained the issues we were having with the clogged drains. He also inspected the units outside and recommended seasonal tune ups for the systems.

"The original technician that was sent to do the job did his best but after a series of issues and 2 days of attempting to remedy them I concluded that he was in over his head.  In his defense, this type of sensor faucet is pretty new on the market and he had limited experience with this particular kind of installation.
I ended up contacting the company owner, Bob Muller.  He listened to my concerns and he took immediate action to resolve them by offering to finish the job himself.   Bob arrived within an hour of our conversation to do the work and within another hour he had the faucet working perfectly. He also checked the work that had been done on the toilets to make sure that everything was done correctly.  I'm a stickler for doing things right and up to code and Bob was on the same page with me.  It's not easy to find a really good plumber.  Bob has earned my future business.

"My water heater went out, needed it replaced the same day, called plumbing Plus in the morning, had it fully installed water heater with the old one gone by noon. Robert answered all of my questions and concerns. If I have any other plumbing jobs I will call on them. Robert was knowledgeable, efficient, and friendly."

Water Softeners FAQs, answered by experts

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.

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

Most experts agree there’s not much difference health-wise between hard water versus soft water. That said, hard water is more likely to cause skin dryness and issues that go along with it, like an itchy or flaky scalp. Hard water can also decrease the life span of your household appliances and make it more difficult for soap to do its job.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

It’s unlikely that hard water on its own could cause substantial hair loss or damage, though it’s true that bathing in hard water can cause your scalp to feel itchy or flaky and might dull your hair’s natural shine. Using high-quality shampoo and conditioner or buying a whole-home water softener can decrease these issues.
