"Rick advised me via text message what to do to get the system up for a soft restart right away. Then he came to my home, tested my water, and made all the necessary adjustments to make sure the system was working properly. I didnâ t buy the original system from Rick and now I wish I had. I high recommend him!"

"Not good. The water leaks had caused black mold that had to be repaired. When repairs were completed 3 months later, the valves still leaked from the stem when turned on. It was past 60 days so I had to pay another $100 service fee to have the water leaks fixed. He tightened the packing and quoted $350 to replace the valves. Sheesh."

"Originally I contracted with him because we had a lot of water in my basement.  The water was pretty high.  I had a few people off of Angie’s List come look at it and they were giving me estimates between $20,000 to $25,000.  The guy who came in from Concrete Raising gave me some good advice.  He told me not to start with an expensive solution.  He told me to try the sump pump first and see if it would work.  It seems to have solved the issue and it only cost me $4000.00."

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.

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs

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.

Water softeners have many benefits. The most important one is converting previously hard water—water with too many minerals—to more usable, easier water. When we say easier water, we mean water that’s easier to digest, less harsh on skin and clothes, and builds up less in the water system. Softer water may lead to lower energy costs and will extend the lifespan of all appliances that use water.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.
