"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"Had an emergency in the early evening. No water. Pump controller burned. Worked with Ben (President) until 10:30PM to get ready to fix the first thing in the morning. Great to work with. They are not cheap, but after checking material prices on line, I believe the pricing is fair. I would use them again in a heart beat! Hope I don't have to though."

"The experience with Randy was fantastic. I had reached out to few places, most did not respond, Randy called me back within literally 30 minutes or less. He was able to come to the house same day and take care of the issue. He was in constant communication, explaining ( in some cases was really teaching), what the issue was and how he was fixing it. I can not recommend him enough nor really thank him enough for the time he put in to solve the issue with my water softener. I would hire him again in a nano second for any job."

"Called AYS Plumbing for a water heater install. The service tech Mike Garcia was very prompt and very professional. He explained what he was going to do and what it was going to take to get the job done. Mike cleaned up after himself and also got rid of my old water heater. Definitely will be using AYS for my future plumbing needs. Mike Garcia was very professional and very knowledgeable. Thanks again Mike, 10 starts from me!!!!!"

"Only good things to say about McLay Services! From scheduling the services call to getting the work done. The technician was up front with pricing and told me only what needed to be repaired on my water heater. He even did a free safety check on my furnace and found a dirty air filter that needed replacement. I will be calling again in the future."

Water Softeners FAQs, answered by experts

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.

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.

Choosing involves understanding water hardness levels, household size, desired features, and consulting professionals experienced in suitable system types.

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.
