"Shaun Boyd talked me into replacing my current perfectly working water system. He claimed that by replacing the current well pump control with a Pentec PID10 constant pressure control would eliminate the need for large water holding tanks. I agreed to follow Shaun's recommendation mainly to provide space for an in-house oil tank and replacing the in-ground tank. After the installation of the new system I found that the new system made such a loud noise that you could hear it one flight up. Shaun returned to fix the problem, however after he left the same problem persisted. I tried calling/texting Shaun many times over a three week period and he refuses to acknowledge my calls and texts. Shaun provided a three year guarantee on the overall system. If this is the way Shaun stands behind his work, I would recommend to anyone seeking his services to think twice about hiring him. My next course of action will be to contact my attorney. I regret having to do this but I have no other recourse if he continues to be non-responsive."

"When something breaks that you have no experience with, you're doing more than just looking for someone that will fix it. You're putting your faith into someone to do the job and at the same time not take you for a ride for all you're worth. Mark was that professional for us when our water heater went. He was knowledgeable, skilled, and his rates were very reasonable compared to others. It was a pretty extensive job. Mark ended up installing a combination water heater and boiler unit to replace the broken system and our ancient boiler. He left our basement better than when he started. We definitely recommend him and will be returning to him for future projects. "

Total Plumbing offers a variety of plumbing services to meet your needs. Our family owned business guarantees your satisfaction. Services offered include, but are not limited to, hot water heater installation and repair, water softener installation, plumbing leak repairs, and new appliances and fixture installation. Contact us by phone, text, email, or the Angi app to schedule an appointment to service your plumbing needs.

"⭐️⭐️⭐️⭐️⭐️ Kevin at Total Plumbing is the absolute best! Our Navien combo system was acting up, and another company (T Webber) told us it needed to be replaced entirely—for $7,000—even though it was still under warranty and this fee was just for their labor! Thankfully, we called Kevin for a second opinion, and we’re so glad we did! Kevin quickly identified the real issue and assured us the unit didn’t need to be replaced, just repaired with a few new parts. He fixed everything for a fraction of the cost and saved us thousands of dollars. His honesty, expertise, and professionalism are unmatched. Thank you for being so reliable and trustworthy, Kevin! Highly recommend Total Plumbing to anyone in need of an honest and skilled plumber!"

FAQs for water treatment & purification system repair or service projects in Walden, NY

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
