Reverse Osmosis System Installation
Reverse osmosis installation adds an under-sink system that pushes water through a semipermeable membrane, reducing dissolved solids and improving taste. RO systems typically include sediment and carbon pre-filters plus a storage tank for on-demand water. FlowFast connects you with an independent local plumber for professional RO installation.

Water Softeners & FiltrationHard water spots or chlorine taste? Water softener vs. filtration options and how to get connected with an independent local plumber for installation.
View all Water Treatment servicesReverse osmosis is the most thorough common residential filtration method available for drinking water. Water passes through sediment and carbon pre-filters, then the RO membrane itself, which rejects a high percentage of dissolved solids, including many minerals, salts, and other contaminants that simpler filters leave behind. A small storage tank under the sink holds the filtered water so it flows on demand, and a dedicated faucet dispenses it separately from the main tap.
Installation involves more than just mounting filters under the sink. The system needs a cold-water feed, a drain connection for the reject water, and enough space for the tank and filter assembly. Membrane life and performance depend on adequate feed pressure and timely pre-filter changes, so these details are checked first. FlowFast connects you with an independent local plumber who will verify your water pressure, install the system with proper drain and feed connections, and sanitize everything before first use.
Warning signs
Signs you need this service
- Your drinking water tastes off, and simpler filters have not improved it enough for your liking.
- A water test shows high total dissolved solids that carbon filtration alone will not reduce at all.
- You want a dedicated supply of highly filtered water for drinking and cooking every single day.
- You are tired of buying bottled water and want a permanent under-sink solution for your kitchen.
What to expect
The process, step by step
The pro checks under-sink space, feed water pressure, and drain access for the RO assembly installation.
They mount the filter unit and tank, connect the cold-water feed, and tie in the drain line properly.
Filters and the membrane are installed, and the entire system is sanitized and flushed clean first.
The tank fills, water is tested for reduced dissolved solids, and filter change intervals are explained.
Prevention
How to avoid this problem
- Change pre-filters on schedule, since clogged pre-filters shorten expensive membrane life considerably and hurt water quality.
- Sanitize the system yearly when changing filters to keep the tank and lines fresh and clean.
- Check the storage tank's air pressure periodically so water dispenses at a good flow rate.
