Reverse Osmosis System Installation Service
Call Now (855) 557-9600
Reverse osmosis system installation removes lead, nitrates, arsenic, and chlorine that pass through whole-house filters, forces supply through a semi-permeable membrane blocking contaminants at the molecular level, and delivers purified drinking water to a dedicated faucet at the kitchen sink. Bonded Plumbworks’ licensed plumbers mount the multi-stage housing, install the RO faucet, and route the drain through an air gap fitting before commissioning. RO systems reduce total dissolved solids by 95 to 99 percent — verified by NSF/ANSI 58.
Reverse osmosis system installation is a water treatment service that sets up a multi-stage filtration system using a semi-permeable membrane to remove dissolved contaminants from drinking water. RO systems reduce total dissolved solids (TDS) by 95 to 99 percent and remove lead, chlorine, fluoride, arsenic, nitrates, pharmaceuticals, and most other dissolved contaminants. — Bonded Plumbworks
What Is Reverse Osmosis System Installation
Reverse osmosis system installation involves mounting a multi-stage filtration unit under the kitchen sink, connecting it to the cold water supply line, installing a dedicated purified water faucet on the sink or countertop, connecting a storage tank, and routing a drain line for the RO system’s reject water. A typical residential RO system includes 3 to 5 filtration stages.
A standard residential reverse osmosis system includes a sediment pre-filter (Stage 1), a carbon pre-filter for chlorine removal (Stage 2), the RO membrane (Stage 3), and a post-carbon polishing filter (Stage 4). Premium systems add a fifth stage for alkaline remineralization that adds beneficial calcium and magnesium back to the purified water, improving taste and raising pH. — Bonded Plumbworks, serving homeowners since 2006
The RO membrane is rated by gallons per day (GPD) capacity — a 75 GPD membrane produces enough purified water for a typical four-person household. Feed water pressure must reach a minimum of 40 PSI for the membrane to function efficiently; homes with low pressure may require a booster pump during reverse osmosis system installation. A permeate pump uses the hydraulic energy of the reject water stream to push purified water into the storage tank without electricity, increasing system efficiency by 50 to 80 percent. All RO systems installed by Bonded Plumbworks carry NSF/ANSI 58 certification, the independent standard that verifies reverse osmosis system installation removes contaminants at the claimed reduction rates.
When to Schedule RO System Installation
Reverse osmosis system installation delivers point-of-use purification removing lead, nitrates, arsenic, and TDS for households requiring the highest possible drinking water quality.
Contact Bonded Plumbworks when:
- You want the highest possible drinking water quality
- A water test shows elevated TDS, lead, nitrates, arsenic, or fluoride — reverse osmosis system installation provides arsenic removal to below 10 ppb (the EPA MCL) and nitrate removal to safe levels for infant formula preparation
- You are concerned about pharmaceutical residues in the water supply
- You currently buy bottled water and want a permanent home solution
- Your water has an unpleasant taste or odor despite whole-house filtration
- You have a family member with a compromised immune system who needs highly purified water
RO provides drinking water purity that no other residential treatment method matches. It is the gold standard for point-of-use water purification.
The EPA sets maximum contaminant levels (MCLs) for over 90 substances in public water supplies, but many contaminants have no federal regulation. Reverse osmosis removes both regulated and unregulated contaminants, including per- and polyfluoroalkyl substances (PFAS), pharmaceutical residues, and microplastics that conventional treatment does not fully address. — Bonded Plumbworks
How RO System Installation Works
Step 1: Site Assessment. We evaluate under-sink space, cold water supply access, drain proximity, and whether a countertop or sink-mounted faucet is preferred.
Reverse Osmosis System Installation assessment gives you a clear picture of the situation before any work starts. You review the findings and approve the quote before any repair begins. Step 2: System Selection. Based on your water quality test results and household drinking water volume, we recommend a system with the appropriate membrane capacity (typically 50 to 100 GPD), number of stages, and optional features like remineralization.
Step 3: Faucet Installation. We drill a hole in the sink or countertop (if no existing spare hole) and mount the dedicated RO faucet.
Step 4: System Mounting. The RO filter housing is mounted inside the cabinet, and the storage tank is positioned for easy access.
Step 5: Plumbing Connections. We connect the system’s feed line to the cold water supply via a saddle valve or dedicated tee, route the drain line to the sink drain via an air gap fitting (required by applicable codes), and connect the storage tank.
State building codes require an air gap connection between an RO system’s drain line and the sink drain to prevent potential cross-contamination through backflow. The air gap fitting mounts on the sink or countertop and provides a physical break between the RO drain line and the plumbing system. — Bonded Plumbworks
Benefits vs. Alternatives
| Purification Method | TDS Removal | Lead Removal | Contaminant Range |
|---|---|---|---|
| Reverse Osmosis | 95–99% | >99% | Broadest (molecular level) |
| Carbon Block Filter | Minimal TDS | Moderate | Chlorine, taste, sediment |
| UV Purification | None | None | Bacteria and viruses only |
| Pitcher Filter | 5–20% | Varies | Limited |
RO is the only residential system that removes dissolved solids at the molecular level, including contaminants that carbon filters and UV systems cannot address. PFAS removal (per- and polyfluoroalkyl substances, also called “forever chemicals”) requires the molecular-level filtration that only reverse osmosis system installation provides at the residential scale. Microplastics filtration is inherent in the RO process, as the membrane blocks particles far larger than its pore size. A point-of-entry (POE) system treats all water entering the home and can pair with a dedicated reverse osmosis system installation at the kitchen for a two-tier approach: whole-house treatment for bathing and laundry, plus RO-purified water for drinking and cooking. For renters or homeowners who cannot modify plumbing, a countertop zero-installation RO unit connects directly to the faucet aerator and requires no permanent plumbing changes.
Pricing
RO system installation pricing depends on the number of filtration stages, membrane capacity, optional features (remineralization, UV post-treatment), and faucet installation requirements. Under-sink systems with existing faucet holes cost less than installations requiring new countertop drilling. Bonded Plumbworks provides upfront pricing. Call (855) 557-9600 for scheduling.

We work exclusively with NSF/ANSI 58-certified RO equipment from manufacturers including Pentair, iSpring, and APEC — verifying that every system we install meets independently tested contaminant reduction standards. Our technicians receive manufacturer training on RO system configuration, membrane sizing, and pressure requirements. Bonded Plumbworks is fully licensed, bonded, and insured for all water treatment installations.
FAQ
How much water does an RO system waste? Traditional RO systems produce 3 to 4 gallons of reject water for every gallon of purified water. High-efficiency models reduce this to a 1:1 or 2:1 ratio. The reject water goes to the drain and is safe for other uses if captured.
How often do RO filters need replacement? Pre- and post-filters should be replaced every 6 to 12 months. The RO membrane lasts 2 to 3 years with proper pre-filtration. Bonded Plumbworks provides replacement service and can set up a maintenance schedule.
How much does reverse osmosis system installation cost? Reverse Osmosis System Installation typically costs between $300 and $800 for most homes. The final price depends on system capacity, installation complexity, and additional plumbing connections needed. Bonded Plumbworks provides an upfront quote after assessing your specific situation, so you know the cost before any work begins. Call (855) 557-9600 for a detailed estimate.
Can I connect an RO system to my refrigerator or ice maker? Yes. Bonded Plumbworks can route a line from the RO storage tank to your refrigerator for purified water and ice. This is a common add-on during installation.
