"Western Rooter to the rescue again! I had a small underground leak which appeared to be due to a bad sprinkler valve. A sprinkler repair company determined that it was not a bad sprinkler valve and thought it was due to a leak in the main water line. Daniel and Alex dug down to find that the leak was coming from a very old (at least 36 years) broken pvc line. After much testing and head scratching to try to figure out where the water was coming from, they decided to "chase the pipe." After much digging, they found that the very old broken pvc pipe was hooked up to a sprinkler valve that was buried 18 inches underground that had not been capped--only turned off. Roots from a nearby tree had opened the valve which caused the leak--crazy! The current sprinkler system has been the same one since we moved into the house in 1988. It took 36 years for the underground leak to occur!"

"After speaking with Kevin (CEO) about the merits of the One Water System, and my own online followup, I bit, and was scheduled for installation 5 days later. Juan, the installer was on time, courteous, self-effacing, humorous, knowledgable and highly skilled. He replaced the ugly functioning plumbing (piping) with a more contoured professional appearance. After the system instalation, function test, old water softener packed and area cleaned. I was given an outline of positives results to look for.  And, as of 2 weeks after installation, I am very pleased with results. Faucet run faster, wife says hair and skin feels better. Good professional results from beginning to end.

FAQs for water treatment & purification system repair or service projects in Los Angeles, CA

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.
