"This review is a long time overdue but I really wanted to give Stuart and his team a shoutout for the great job they did. I had Pipeline to come out to Waianae to install 2 toilets and a shut-off valve at my home. Not only were they willing to come this far, but also, Stuart and his team gave the absolute best customer service where nowadays it is rare. His team was fast, clean, respectful and efficient and his pricing very fair for the job. One toilet installation proved to be trickery than anticipated, but they went the extra mile to get the job done. And when it came time to do the shutoff valve, I really was fully frustrated with finding the public water source. However, Pipeline's team member was persistent and got the job done all while maintaining a great attitude. I would definitely recommend Pipeline Plumbing. As a landlord, I have been through my share of repairs and good companies like Pipeline are essential and just plain sanity saving."

"When I was told the cost of the job would be $505.00 plus tax, I was shocked. He told me that the price was set by the company. I had $60 coupon, so it came out $465.00. Since he’s already at my home, I gave him ok. I couldn’t send him back because I was afraid there would be a charge for the visit whether I use his service or not. The job took approximately 30 mins excluding time he spent loading and unloading his tools. I felt so stupid for paying that much for 30 mins job."

"Brennan came over at the scheduled time and was able to assess, provide options and pick up the desired faucets that was selected. We replaced both the bathroom and kitchen ones as they were worn out and needed to be changed out. Although it was great service, I would say that the final price was a bit larger than I initially anticipated. But considering that these fixtures are supposed to last for a long time, you pay the money to do it right once and you never have to pay again for repairs or service, so it balances out but have money ready....they charge 3% on credit card transactions and that turned out to be too much on top of a hefty bill."

FAQs for water treatment & purification system installation and replacement projects in Lihue, HI

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.
