"They performed appropriate tests on my softened and filtered water before doing any work. No major repairs were needed, only targeted maintenance was needed. They were thed only water filtration rane changes from this point forward. Finding these folks is loke hitting a home run.company that offered a service to deliver salt to us, carry the salt to our basement, then install the heavy salt into our salt bin. And their price for doing that is more than fair. We will be having them provide routine maintenance & filter/membrane replacement."

"I was referred to Superior Plumbing and within 3 years of contacting them their employee was at my home and working on the back up in my storm water drain running to the street. Angel was quickly able to trouble shoot and assess my problem and solve the issue. He was extremely patient and pleasant explaining the problem and resolution. I would definitely recommend Dean and his team to friends, family and co-workers. Pendleton NY resident"

"Immediate call back, out to assess within a few hours.  Immediately recognized that having water in the radiators could be a major problem and had us drain them (something that was not told to us by a company the prior day), and also that we could be at risk for our water pipes to freeze.  They came out the following morning at 8 am, on time, replaced the system, vented it out of the side of the house, temperatures sub zero the entire morning.  Finished work by 5:30 pm.  Professional, courteous.  Covered their shoes inside the house.  Installed all new CO monitors and fire alarms.  Good prices.  Couldn't have asked for better service.

Water Softeners FAQs, answered by experts

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.

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.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.

Hard water isn’t necessarily bad for you. In some ways, it’s good for you. If you’re deficient in magnesium or calcium, hard water can give you a mineral boost that you wouldn’t get with soft water. However, this is where the benefits of hard water pretty much stop. Hard water can cause many minor inconveniences and lead to costly, premature replacements of your water-using appliances.
