Whole House vs. Under-Sink Reverse Osmosis Systems
Not all RO systems are built the same, and the right fit depends on your household’s needs. Here’s a quick breakdown of the two most common options:
- Under-sink reverse osmosis systems are the most popular choice for Phoenix homeowners. Installed beneath your kitchen sink, these compact systems connect directly to a dedicated faucet and filter water on demand. They’re ideal for families who want high-quality drinking water and cleaner-tasting ice without a major plumbing overhaul. Most under-sink RO systems produce between 50 and 100 gallons of purified water per day, more than enough for a typical household.
- Whole house reverse osmosis systems – also called point-of-entry systems. These connect to your home’s main water supply line and filter every drop of water that enters the home. This option is better suited for households with well water, extremely high TDS levels, or specific concerns about water quality at every tap and appliance throughout the home. These systems require more extensive installation and larger storage tanks, but they deliver filtered water everywhere in the house.

Where Can You Install a Reverse Osmosis System?
One of the most common questions we get is where an RO system can actually go. Reverse osmosis filter installation is more flexible than most people expect. Common installation points include:
- Under the kitchen sink – the most popular location, connected to a dedicated filtered water faucet
- Refrigerator line – many RO systems can supply filtered water and ice directly through your fridge
- Bathroom sink – for households that want purified water in multiple rooms
- Whole home entry point – for point-of-entry systems that treat all water coming into the house
Our technicians will assess your home’s existing plumbing during the visit and recommend the best placement before any work begins.
The Cost of Installing a Reverse Osmosis System
Factors Affecting Installation Cost
The total investment for a reverse osmosis system installation depends on several variables, including:
- System type – under-sink systems are significantly less involved than whole house reverse osmosis systems, which require larger components and more extensive plumbing work
- Number of filtration stages – more stages mean more thorough filtration but a higher upfront cost
- Your home’s existing plumbing – straightforward setups are faster to complete than homes that require additional modifications
- Ongoing filter replacement – pre-filters typically need replacing every 6–12 months, while RO membranes generally last 2–5 years, depending on your water quality and usage
Is a Reverse Osmosis System Worth the Investment?
For most Phoenix homeowners, the answer is yes and the savings will show up quickly. When you stop buying cases of bottled water or paying for a monthly delivery service, that expense disappears. Beyond drinking water costs, an RO system also reduces the mineral load on your appliances and plumbing over time, which can meaningfully extend their useful life.

Servicing a Reverse Osmosis System
Repair
Even a well-maintained RO system can run into issues over time. Common problems include slow water flow, a drop in water quality, leaks at the fittings, or a storage tank that isn’t pressurizing correctly. If your reverse osmosis drinking water system isn’t performing the way it should, our technicians can diagnose the issue and get it running properly again. We service all major RO system brands and carry the parts most commonly needed for repairs.
Tune-ups & Maintenance
Keeping your RO water filtration system in top shape comes down to staying current on filter replacements and periodic system checks. A standard maintenance visit from Rite Way typically includes:
- Pre-filter and post-filter cartridge inspection and replacement as needed
- RO membrane check. Membranes typically last 2–5 years, depending on Phoenix water conditions and household usage
- Storage tank pressure check
- Faucet and fitting inspection for leaks
- Overall system performance test to confirm water quality
Staying current on maintenance keeps your system producing the clean, great-tasting water your family counts on and helps you avoid the more costly repairs that come from deferred upkeep. We recommend scheduling a tune-up once a year for most Phoenix households.
