What Is Reverse Osmosis Filtration?
A proven, multi-stage process for cleaner, better-tasting water
Reverse osmosis (RO) is a multi-stage purification method that pushes water through a semipermeable membrane to remove dissolved solids and contaminants. A typical system includes a sediment prefilter, carbon filtration, the RO membrane, a storage tank, and a final polishing filter. This process can reduce lead, arsenic, PFAS, nitrates, fluoride, microplastics, and chlorine taste and odor—often achieving 95–99% reduction in total dissolved solids (TDS) when the system is properly sized and maintained.
Beyond safer water, RO dramatically improves taste for drinking, cooking, coffee, and ice. Systems can feed a dedicated faucet at the sink, a refrigerator/ice maker, or both. Options include remineralization cartridges to enhance pH and flavor, permeate pumps to improve recovery and reduce wastewater, and NSF/ANSI 58 certified components for performance and reliability.
Sized, plumbed, and tuned for peak performance
Every installation starts with a quick site assessment to confirm water pressure, space, and connection points. I install reliable feed valves, code-compliant drain connections (including air-gap faucets where required), and secure brackets to protect tubing and components. Faucet holes are drilled cleanly in stainless, composite, or stone, followed by pressure testing, sanitizing, and a full leak and flow check so your new system performs from day one.
Upgrades can tailor an RO to your home and usage: compact manifolds for tight spaces, larger tanks for higher demand, refrigerator/ice-maker connections, UV post-treatment, alkaline remineralization, and leak-detection shutoff valves. I route and label lines neatly, set the correct flow restrictor for your membrane, and provide a clear walkthrough of operation and maintenance. All work is backed by a written workmanship warranty.
Keep your system clean, efficient, and long-lasting
Routine maintenance is the key to water quality and system longevity. Sediment and carbon prefilters typically need replacement every 6–12 months based on water quality and use, while RO membranes often last 2–5 years. I sanitize tanks and housings during service, verify air pressure in the storage tank, replace O-rings as needed, and confirm performance with TDS testing or inline monitors.
If your system has slow flow, off-taste, continuous draining, or short-cycling, I provide fast diagnostics and repairs. Common fixes include resolving clogging, replacing auto-shutoff valves and flow restrictors, correcting drain saddles and air gaps, and restoring proper tank pressure. I service most major brands and stock quality parts to minimize downtime.
With over 25 years of hands-on plumbing experience, I began installing water treatment equipment in 1995 and earned my Journeyman License in 1999. As an independent plumbing contractor, I deliver personalized service without big-company overhead—saving homeowners an average of $250 compared to the regional industry average while maintaining top-tier quality.

Maribeth Gossard2025-08-10Trustindex verifies that the original source of the review is Google. I highly recommend Parkhurst plumbing. Larry is great and knowledgeable at what he does. He recently installed a new water softener (replacing old one) for us. He recommended a system that I didn't really think I needed. However, now that I have it, I can't believe I questioned needing it! I have never had such fabulous soft water. It is so silky and lovely that I don't want to get out of the shower. He also installed a carbon filter (as part of the water softner system) to remove all the chlorine and nasty stuff from the water. Wow, what a difference it has made. I can actually drink the tap water (I am used to RO water). I cannot say enough about this system. While he was here, we also had him replace a kitchen faucet and work on a bathroom faucet. All completely satisfied! If you need someone honest that you can trust, look no further. You will not be disappointed.
