"We recommend Fellowship Plumbing and Mechanical without reservation. Kyle,the owner, delivered excellent service with a professional, courteous, caring attitude and impressive follow-through in all phases of our interaction. We found him, his employee, Eric, and their office manager (Kyle’s aunt) to be uniformly great to work with: from first contact, through assessment and estimate, to work completion. They all impressed us with their professional attitudes. We needed a new toilet, since the one we inherited constantly malfunctioned. We have a septic system so we wanted to make sure we installed something that would not strain our system but would work reliably for years. Although I had researched options for a month, I wanted to hear what a professional would say. We asked Kyle for advice. He inspired confidence during the discussion. He recommended a great fixture, and the toilet installation was done on time, efficiently, and cleanly. He and Eric left the bathroom neat and without any kind of debris, and even though the day of installation was raining heavily there was no mess at all from coming in and out—they treated our property with respect and consideration. We are seniors, and we are paying for this work out of Social Security — so the small discount they offer was welcome, but, even more importantly, the work estimate was accurate too. No “sticker shock.” So far, we are very happy with the new setup. Kyle’s business is a small one, but a more reliable and courteous business than some of the bigger outfits we have had in the past. Hiring workmen can be ridiculously stressful and frankly occasionally infuriating. We had a small business ourselves, so I really am stunned sometimes by how badly some people run theirs. SO often I can’t get plumbers or workmen to follow through on one or more steps in my hiring process; either they don’t come on time or when promised (!), disappear after we ask for a written estimate, or charge us unnecessary fees up front. Plumbing/reliable sanitation is an essential need in every home, and can probably be a difficult profession; but it is necessary for health and well-being. What a pleasure, then, to recommend Kyle’s Fellowship Plumbing and Mechanical. They provide an professional service from start to finish."

Water treatment & purification system installations and replacements FAQs

Water softeners consist of three main components: a mineral tank, a brine tank, and a control valve. In some smaller units, the mineral tank and brine tank are combined into one cabinet.

Professionals install whole-home systems at the point of entry of the main water line. Smaller units are installed under sinks or near a washer—these units only soften the water for that fixture, not the entire home.

  • Mineral Tank: Hard water passes into the mineral tank through resin beads, and an ion exchange occurs. Magnesium and calcium ions are exchanged for sodium or potassium ions from the brine tank.

  • Brine Tank: The brine tank contains sodium or potassium to recharge the resin.

  • Control Valve: The control valve determines when to clean the resin beads.

Choosing between a salt-based or potassium-based water softener depends on your priorities. Salt-based systems effectively remove hard-water minerals, regenerate efficiently, and are cost-effective. However, they may not be ideal for individuals on low-sodium diets. Potassium-based systems neutralize minerals without removing them and regenerate more frequently. They are more expensive but offer a healthier and more environmentally friendly option. If sodium levels are a concern and cost isn't a major factor, a potassium system may be the better choice.

To calculate your water softener's capacity, determine your grains per gallon (GPG) number by:

  • Multiplying the number of people in your home by 90. The average number of gallons used per person for washing, drinking, and cooking ranges from 80 to 100 gallons per day.

  • Multiplying that result by the hardness of your water. The average grains per gallon in the United States is 10 but can range from 0 to 17. You can find your GPG number by purchasing an at-home water testing kit.

Installing a water softener takes between two to four hours on average. The exact duration depends on the complexity of the unit and whether additional plumbing or electrical work is required. If modifications to existing pipes are necessary, installation may take longer. Preparing the installation area by clearing any obstructions can help streamline the process.

Water softeners can last up to 25 years with proper maintenance and care. The lifespan depends on the type and quality of the unit you choose. Single-tank electric water softeners may last around 12 years, while higher-quality models tend to last longer. Regular maintenance, such as routine inspections and timely replacement of salts or potassium, helps extend the life of your system. Most water softeners require minimal repairs over their lifespan.
