"Super Happy with this Co.. They swung by the same day on their way home from work to evaluate the situation & gave me a quote. Followed through efficiently & went above & beyond with the clean up & replacement of my water heater. Very polite & respectful, just great guys. I have finally found a company who does great work & they don’t take advantage of you financially. I highly recommend Nelson Plumbing."

"The water here in Manteca is terrible. It smells, tastes disgusting and leaves your skin dry and ashy. I research water softeners/purifiers online and with my neighbors and then contacted AAA Water Systems since they use the Kinetico water systems. I had an appointment with Damian Fernandez and he was very thorough in his explanations of the system, how it works, maintanence, future costs, just everything I needed to know to make an informed decision. And it was the best decision ! I know have purified water right at my sink from the reverse osmosis sytem and soft smell free water from all the taps. No more hard water deposits, no ashy skin and coarse hair. No more bottled water to drink or cook with. The installers were wonderful...prompt and professional. Everything spotless when they were done. They carefully explained and showed me how to use, maintain, and just in case, shut the system off. They also provide little measuring scoops for the proper amount of soap to use in the washing machine and the dishwasher."

"I was in the need of getting a garbage disposal installed and an electrical socket since there was only a hardwire access that was very old wiring from when the house was originally built. These guys were very professional prompts they came out right away! The prices were reasonable and I really appreciated their help. I had already contacted two other plumbers to see about the job. They charged me to come out and they didn’t get the work done but these guys they came out they looked at everything they didn’t charge me just to just diagnose it they told me upfront what it was gonna cost and we were able to come to an agreement. I really enjoyed working with them. Would definitely recommend or hire them again."

"HORRENDOUS EXPERIENCE! They came out, stated my installed tankless system needing repiping didn’t have a recirculating pump built in & recommended I get one. They quoted $99/hour for labor & parts are separate. Stated there were no options for an external pump (not on market) & wanted me to purchase their system with one built in requiring to uninstall NEW system & install their system (thousands more) & stated it would require 2 men for 8 hours of work & appointment was booked. After researching, there are both universal recirculating pumps for tankless systems & the brand I had made an external pump specifically for the system I bought. When I told them this & that I would only need to have the system already in place properly pipped with external pump installed, they became hateful from that point on & demanded I had a non-working outlet next to system fixed before they would do any work (didn’t have this demand when I booked appointment with their system). I had already fixed the outlet but the lady who answers the phone repeatedly stated no work would be done until outlet fixed, even after I told her I heard her the first 5 times & would ensure it was done, she continued demanding every communication in a hateful tone, multiple times each communication. Was told I would get a new bid with their tankless system removed & labor hours adjusted, it took a week to get it & just 2 days before the appointment. I was shocked to see the bid was still high ($1300) since the system was already installed but only needed repiping & recirculating pump installed. I sent an email, I only requested to know how many hours they expected to need that day, she responded by telling me the appointment was cancelled & I should find another plumber. They cancelled 2 days before because I dare ask how many hours were needed on a $1300 estimate. Not only did they not know of universal recirculating pumps for tankless systems, or lied to sell me their system, but they wanted 11-12 hours of work (estimate not detailed so I estimated $100-200 for some parts) to repipe an already installed system & install a external pump. They are dishonest people & cancel if you inquire about the estimate which I believe was highly bloated. I will never use them again, buyer beware!!!"

"This is the third time we've used Pacific Plumbing and they get an A+. We called them and an hour later, four men were here. They had to flush out the entire water line from the street to the house. It took about 2.5 hours and then the toilets worked and the water had drained from the showers. They used the latest equipment, including a camera they sent into the line to be sure it was all clear. I can't recommend them strongly enough. The cost was completely reasonable."

FAQs for water treatment & purification system repair or service projects in Fresno, 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.
