Our goal at Allegiance water is to make sure you know more about your water when we leave then before we came. With 15 years experience in water treatment with the major water softener companies we have set out on our own and created Allegiance Water LLC. We felt that there were areas where we could do much better then what we had seen over the last decade and a half in the industry. The major thing we do is educate service save you money but not sacrifice on quality. The key to getting the best equipment at the best prices is having options, and keeping overhead to a minimum. Overhead is directly passed onto the customer we know that if we keep our spending on overhead down yet still able to get the same systems others offer with a great 10 year warranty than we will be much more competitive than anyone else. We also know not one manuf. has all the answers, we use multiple suppliers to assure we are getting the best equipment for your individual needs and to fit your budget!

"Nothing installed yet, but was quick to quote, tested our water, & cares about his customers. Not just about a sale."

Reasonable rates and after hour work. Licensed with 20 years experience and union trained. We do everything from remodels to emergency calls. Possible work, but not limited to: Clogs, drain cleaning Re-pipes Fixture installs Water heaters and softeners Disposals and dishwashers Pools Sewer and septic Sump and well pumps Water treatment, filtration and UV units Tankless water heaters Radiant heat In addition, Fitzgerald Mechanical is capable of completing all construction from foundation to key in the door. We belong to a co-op of skilled trades that will provide the convenience of only having to work with one contractor from start to finish.

"I gave Ryan and Heather a $6,500 deposit for their bid to replace my main sewer line on Oct 15, 2019. They dug two 4 foot holes in my backyard and then disappeared for 5 months. I called, emailed, and texted every few days letting them know the sewage leaking in my basement was getting worse by the day. Over the 5 month period they would either completely ignore my communication or give me excuses ranging from being gone on hunting trips to moving on to other jobs and promising that I was still a priority to them and that I was next on their list. It finally came down to me getting another contractor to come do the job, and they were able to complete it in 2 days. I asked Ryan and Heather for my deposit back and after a week of excuses why they wouldn't be able to get me my check I told them I felt I had no choice but to sue them because I needed the money to pay the other company that actually did the work. They eventually gave me a partial refund with no explanation of why they kept $2,500 of my money. I've messaged them to see if they can explain how they can justify it, and they haven't gotten back to me. I would strongly recommend not using their services, especially if it involves a deposit up front. Ryan and his crew were very nice, and I enjoyed the time I got to spend with them, but I've never been so frustrated working with a contractor. I feel cheated and in my opinion they simply stole $2,500 from me."

FAQs for water treatment & purification system installation and replacement projects in Caldwell, ID

A whole-house water filtration system is ideal if you want all the water in your home to be filtered, improving water quality and protecting your plumbing. This system can enhance your home's value. If you only need filtered water for drinking or cooking, a point-of-use filter might be a suitable alternative. Each filtration option is designed to remove specific contaminants.

Maintaining your whole‑house water filtration system is essential for uninterrupted performance and clean water. The annual expense, which ranges between $50 and $300, covers filter replacements, complete system inspections, and any required repair work. Regular maintenance keeps the system operating at peak efficiency and guarantees the highest water quality for every home use.

Installing a whole‑house water filtration system is a streamlined process that a professional can complete in one day. Multistage systems require additional time to secure proper plumbing connections and calibrate the system accurately. In contrast, point‑of‑use filters are installed within a few hours, ensuring efficient and precise integration in your home.

Most whole-house filtration systems last 10 to 20 years with proper care. Reverse osmosis units typically serve 10 to 15 years, while water distillers can exceed two decades. Lifespan depends on build quality, water chemistry, and whether filters, lamps, or membranes are changed on schedule. Regular professional inspections help you catch minor issues before they shorten the system’s life. Budget for planned component replacements to reach the upper end of that range.

Fast clogging usually points to high sediment levels, heavy water use, or both. When more dirt and minerals flow through the system, filters load up sooner and performance drops. Schedule a water test to confirm what’s in your supply, add a sediment pre-filter if needed, and follow the manufacturer’s replacement timeline to keep water pressure and quality where they belong.
