You deserve a safe and reliable home. Get the job done right the first time with outstanding customer service from the Twin Cities top rated electrician. Outlets, fans, lighting, smoke detectors, switches, and service panels. Your full service electrician.

"The dishwasher wiring that Randy's installed in my home fried out 6 months after they did the work, almost causing a fire in my home. Luckily the circuit breaker enabled to cut power. In the doing the work, Randy's said my Bosch dishwasher had to be hardwired vs. how Bosch sent from the factory. Randy's rewired the Bosch wire box which did not work after they left and they had to come back out because the box was "arcing" and causing the circuit breaker to enact. This should have raised alarms with Randy's but no. Eventually the box melted down, which I did not initially know, causing us to purchase a new dishwasher only to find out by Warners Stellian that the box was fried. Randy's did engage in discussions on the topic but accepted no accountability, initially denying they even did the work. After pressing the issue they finally admitted to rewiring the box but said they can't accept accountability because it was provided by them. When pressed on why they would rewire a Bosch electrical box they would never support vs. installing their own box - they had no answer and said it was a good question. They admitted they should have probably installed their own box and not touched the Bosch box but would still not accept any accountability for their poor workmanship. I was glad to see Randy's admit they should approach these situations differently in the future but very disappointed they would not admit to fault here or warranty the work. Randy's did not act in good faith and I would not use them again. For reference, they were at my house for 4 hours and I was charged $2700 for the work (multiple small projects). They are one of the most expensive outfits you can hire and they claim you get what you pay for. Apparently I paid for a near fire in my house and a $1500 dishwasher opportunity. Disappointed."

FAQs for water treatment & purification system installation and replacement projects in Cottage Grove, MN

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.
