Cleaner, Better-Tasting Water Starts Here
Tired of hard water spots, chlorine taste, or water you don’t trust straight from the tap? Cascade NW Plumbing installs and repairs reverse osmosis systems that filter out sediment, chlorine, heavy metals, and other contaminants — giving you crisp, great-tasting water right at your kitchen sink or throughout your entire home.
From new system installation to repairs, filter changes, and membrane replacement, our licensed plumbers keep your reverse osmosis system running the way it should — throughout the Vancouver, WA and Portland, OR metro areas.
Signs Your Water Needs a Reverse Osmosis System
If your water is giving you any of these warning signs, a reverse osmosis system could make a real difference:
- Bad Taste or Odor — Chlorine, sulfur, or metallic tastes coming from your tap.
- Cloudy or Discolored Water — Sediment, rust, or visible particles in your glass.
- Hard Water Buildup — Scale on faucets, low water pressure, or soap that won’t lather.
- High TDS Readings — Elevated total dissolved solids from a water test.
- Health & Safety Concerns — Lead, nitrates, or other contaminants in older homes or well water.
- Relying on Bottled Water — Spending money on bottled water because you don’t trust your tap.
How Reverse Osmosis Works
Our reverse osmosis systems use a multi-stage filtration process to deliver the cleanest water possible:
- Sediment Pre-Filter — Removes dirt, rust, and larger particles before water reaches the membrane.
- Carbon Filter — Reduces chlorine, taste, and odor.
- Reverse Osmosis Membrane — Forces water through a semi-permeable membrane that blocks dissolved solids, heavy metals, and other contaminants.
- Post-Filter & Storage Tank — Polishes the water one final time and stores it under pressure, ready whenever you turn on the tap.

Frequently Asked Questions
-
How long does a reverse osmosis system last?
With proper maintenance, the system itself can last 10-15 years, though filters typically need replacement every 6-12 months and the membrane every 2-3 years depending on water quality and usage.
-
Should I get a whole-house or under-sink system?
Under-sink systems are ideal if you just want cleaner drinking and cooking water. Whole-house systems treat water at the point it enters your home, which is a better fit if you’re dealing with hard water or contaminants throughout the house. We can help you decide which makes sense for your situation.
-
How often do the filters and membrane need to be replaced?
Most pre-filters and carbon filters should be replaced every 6-12 months, while the RO membrane typically lasts 2-3 years. We can set up a maintenance schedule so you never have to guess.
-
Will a reverse osmosis system remove all contaminants from my water?
Reverse osmosis removes the vast majority of dissolved solids, heavy metals, chlorine, and other contaminants, giving you significantly cleaner water. No system removes 100% of everything, but RO is one of the most effective options available for residential use.
-
Is professional installation necessary?
While some under-sink kits are marketed as DIY, professional installation ensures correct water line connections, proper drain tie-in, and code-compliant work — which protects your plumbing and your warranty.
