Plumbing problems don't wait - neither do we!

Reverse Osmosis Systems

Reverse osmosis (RO) systems provide some of the cleanest drinking water available for homeowners. These multi-stage filtration systems remove contaminants, sediment, and impurities to deliver pure, great-tasting water right from the tap. Melde Plumbing installs, services, and replaces RO systems for homes across western Wisconsin.

Reverse Osmosis in Holmen, WI

Wisconsin water tastes like Wisconsin water. Depending on where you live around Holmen, you might be dealing with well water that smells like sulfur or city water that tastes like chlorine. Either way, you’re probably buying bottled water by the case instead of drinking what comes out of your tap.

Reverse osmosis systems fix that problem right at your sink. You get clean, great-tasting water without hauling plastic bottles home from the store every week. We install these systems under your kitchen sink, and they filter out everything you don’t want drinking.

Why Homeowners Choose RO

RO filtration reduces:

Professional Installation

We install RO systems under the sink or in the basement depending on your home’s layout. We ensure all lines, filters, and storage tanks are installed cleanly and securely for optimal performance.

How Reverse Osmosis Works

The system pushes your water through a really fine membrane that catches contaminants. We’re talking stuff way smaller than what a regular filter can catch. Heavy metals, dissolved solids, chemicals, bacteria—the membrane blocks it all and only lets pure water through.

You end up with a separate faucet at your sink just for the filtered water. It looks clean, tastes clean, and you can actually drink it without that weird aftertaste. People use it for drinking, cooking, making coffee, filling up their kids’ water bottles for school.

The systems we install have multiple filter stages. First stage catches sediment and bigger particles. Then you’ve got carbon filters that pull out chlorine and improve taste. The reverse osmosis membrane does the heavy lifting after that. Finally, there’s a polishing filter before the water comes out of your faucet.

Maintenance is pretty simple. You swap out filters every six months to a year depending on your water quality and how much you use. The membrane itself lasts a few years. We can handle all that for you, or you can do it yourself—it’s not complicated.

If you’re on well water out in the country, reverse osmosis makes even more sense. You don’t know what’s in that water without testing it.

Maintenance and Filter Changes

To keep water quality high, RO filters and membranes need regular replacement. We offer scheduled maintenance or on-demand filter changes to keep your system producing safe, clean water.

When to Upgrade

If your current system is older, noisy, slow, or producing low-quality water, we can help you choose a modern RO system that offers better efficiency, higher flow, and improved reliability.
