"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

Caffi Services has served the DC Metropolitan area since 1967, and has earned the reputation for top-quality products and services at a fair price.

"My partner and I recently moved into a new house in North Arlington and developed kitchen area plumbing problems. Caffi Service Representative Patrick Bache arrived in short order to make all necessary repairs. Patrick worked quickly and efficiently and thoroughly cleaned up when repairs were finished. He answered all our questions and made very helpful followup suggestions. We've been satisfied Caffi customers in Northern Virginia for over 20 years and knew that we would get the same A-1 quality service from Caffi at our new house that we had received over the years at our former address.

FAQs for water treatment & purification system installation and replacement projects in Washington DC, DC

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.
