Reverse Osmosis Repair & Filter Changes in Fresno & Clovis
Slow flow, a leak under the sink, water that tastes off, or filters years overdue — Nick services most RO brands and gives you a straight answer: fix it or replace it.
Your RO system probably isn't broken. It's overdue.
Nine times out of ten, an RO system that trickles, tastes off or has an empty tank simply has spent filters or a clogged membrane. Fresno's water carries enough hardness and chlorine that pre-filters wear out faster than the sticker says. Nick carries common cartridges and membranes on the truck, so most service calls are finished in one visit.
If the leak is from a cracked housing, a failed tank bladder or a unit that's been patched a few too many times, he'll tell you that too — and give you a written price on a replacement so you can compare, with no pressure either way. New RO systems →
Not sure what you have? Text a photo of the unit under the sink to (559) 795-4083 and Nick will tell you what it needs.

Fresno homeowners, in their own words.
Real Google and Yelp reviews of Nick's company. Nothing edited.
Reached out to Nick for a leak on my roof, his communication was prompt and came out the same day to quote. He is very knowledgeable and provided a competitive quote. The roof looks great and he'll be back to replace some additional broken tiles. An honest and good guy to work with, highly recommend.
Nick is very professional and someone you can trust. His variety of services, competitive pricing, and communication/responsiveness make him a pleasure to work with. Highly recommend!
Nick was very prompt on his response and reliable. His crews are easy to work with and respect the property. I would hire his company to do the future home improvements or upgrades.
RO Service, Filters & Repair questions, answered.
Do you service RO systems you didn't install?
Yes — most brands, including APEC, iSpring, Waterdrop, Culligan, Kinetico, Watts, Whirlpool and the big-box units. Text a photo if you're not sure what you have.
Why is my RO water so slow?
Usually spent pre-filters or a fouled membrane; sometimes low tank pressure or a bad tank bladder. Nick checks all four and fixes what's actually wrong.
How much does an RO filter change cost?
It depends on the brand and how many stages you have. Nick gives you the price on the phone or by text once he knows the unit — no trip charge surprises.
Should I fix my old RO or replace it?
If the housing, tank and faucet are sound, a filter and membrane change brings most units back to new. If it's leaking from multiple points or over 10–12 years old, a new tankless system is often the better money. Nick will tell you which, in writing.
Can you fix a leak under my sink from the RO?
Yes. Most RO leaks are at push-fit fittings, the tubing or the drain saddle — quick repairs. Cracked housings get replaced.
How fast can you come out?
Same week, often sooner. Evenings and weekends included.
