"I used them to install a gas line and hook up a new gas stove. Vince was through and very knowledgeable of what needed to be done. The price was exactly what he quoted, the pipe install was very neat and clean and he connected the stove, tested to make sure everything was working as well as check all the existing gas appliances to make sure they were working after turning the gas back on. I will be using Vince going forward for all of my plumbing needs!"

"I called Pipe Works because the 2nd-floor unit was leaking water from the attic through the ceiling. Pipe Works put in a new unit 4 years ago for the 1st floor completing a fantastic job with no issues so I called them to help with my 2nd floor problem. A representative, "John Sorrentino," came out the same day, and explained we needed to replace the 32-year-old unit, which is what we thought. He explained how we could finance the charges which we needed to do. We also were ready to tell him how our 32-year unit never worked properly cooling or heating the 2nd floor. Before even mentioning this to Mr Sorrentino he already knew the old unit did not have the proper ventilation system and therefore we were probably having issues with the HVAC not cooling and heating the floor efficiently. He was right! We are very satisfied customers with our 1st and 2nd floor units. Their knowledge, expertise, willingness to help the customer and overall service is outstanding. Our experience with Pipe Works has only been awesome. Their quick response, knowledge, clear explanation of work to be completed, explaining charges, caring for required permits, and assistance financing the job. I would not call any other company to handle our HVAC needs."

Water Softeners FAQs, answered by experts

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

A water softener is a worthwhile investment if you live in an area with hard water. While hard water is safe to drink, it contains minerals like calcium and magnesium that can cause significant problems over time. These minerals build up inside pipes, reducing water flow and eventually corroding the plumbing system, which can lead to leaks and a shortened lifespan. Hard water also damages fixtures and appliances, potentially resulting in costly repairs. Additionally, it makes soaps and detergents less effective, meaning you'll use more product to get things clean. By installing a water softener, you can prevent these issues. The initial investment is often recouped through long-term savings, including lower energy bills, reduced appliance and plumbing maintenance, and spending less on soap and cleaning supplies. Other benefits include cleaner linens, dishes, and clothing, as well as softer water that is gentler on your skin and hair. In some areas, a water softener can also increase your home's value, making it a valuable long-term investment.

Most of the U.S. has hard water, especially across portions of the West and Midwest. The areas with the hardest water include parts of Texas, Oklahoma, Kansas, Colorado, New Mexico, Utah, Wyoming, Illinois, North and South Dakota, Ohio, and New York. You’ll find soft water in parts of New England, the Southeast, the Pacific Northwest, and Hawaii.

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.
