"John was Great!!! Our first appointment had to be cancelled due to unforeseen circumstances, but John communicated the issue immediately which was much appreciated, and set new appointment. When John came arrived on time (A+) Professional and listened to my idea/suggestion (A+) Did the job in less than the estimated time (A+) Cleaned and REPAIRED the wall area which I didn't expect (A+) Price was 1/3 of what others wanted to charge. Definitely, recommend NorCal Water Treatment to others, and will be rehiring for future plumbing projects/issues. I'm real BIG on customer service/professionalism and John is "The Man!""

"Kirk was able to correct both of my plumbing issues very quickly...a faucet that had very little water coming out and a slow draining sink. He also checked the water pressure at the front of the house..it is a bit high so we are going to decide the next step on this. I am always pleased at the communication from Valley Plumbing and most of all I am pleased with Kirk's professionalism, courtesy and skill in solving my problems. Highly recommended. I felt the price was fair and appreciated the senior discount."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"Before installation, I had a lot of questions and swinging among the products. The staff has been very patient. Installation crew, Anthoney, was on time. He is very professional and knowlegable. The install location he suggested save us thousand dolloars. He also cleaned up after himself. Treated water feels great. Puronics is a high quality product with excellent price. Highly recommanded."

Water Softeners FAQs, answered by experts

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.

Hard water stains can be a headache because they will reoccur as long as hard water flows through. Thankfully, hard water stains are not permanent. With the right tools and an appropriate cleaning routine, you can prevent hard water stains from ever building up. However, you might feel like you are stuck in a constant cleaning cycle. In that case, you may consider hiring a contractor to perform routine cleaning.

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

Water purifiers and water softeners serve different purposes, so the best one will depend on your particular needs. Water purifiers remove contaminants from water (such as bacteria, viruses, and chemicals), leaving you with ultra-clean and safe water. However, water softeners remove minerals from your water so that the water doesn’t leave stains around your house or cause plumbing problems.

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.
