Reverse Osmosis in Danville, VA

A Reverse Osmosis system, commonly called an RO system, improves drinking water by forcing it through a semipermeable membrane with extremely small openings. Sediment and carbon prefilters typically remove larger particles, chlorine, tastes, and odors before water reaches the membrane. The membrane then separates many dissolved substances from the treated water, which is stored in a small tank and delivered through a dedicated faucet. Pro-Flo Plumbing installs Reverse Osmosis systems in Danville, VA, for homeowners who want an additional level of treatment at the kitchen sink.

Contaminant Reduction Based on Water Testing

Depending on its certifications and filter configuration, an RO system may reduce lead, arsenic, nitrates, dissolved salts, PFAS, and certain other contaminants. It can also improve water affected by unpleasant tastes, odors, or high levels of dissolved minerals.

No filter removes everything. The right system should be selected according to the home’s water source and the specific substances present. Municipal-water customers can review the utility’s annual water-quality report, while homeowners with private wells may benefit from laboratory testing before choosing treatment equipment.

Reverse Osmosis and Other Filtration Options

Carbon filters are often effective for improving chlorine taste and odor, but they generally do not remove as wide a range of dissolved substances as an RO membrane.

Whole-house filters treat water as it enters the property, protecting showers, fixtures, and appliances as well as drinking-water faucets. Under-sink RO systems focus on a smaller amount of water used for drinking and cooking.

Some homes benefit from both. A whole-house sediment filter or water softener can protect the plumbing and appliances, while Reverse Osmosis provides more refined treatment at one faucet.

Routine Filter and Membrane Care

RO systems require periodic prefilter, postfilter, and membrane replacement. Replacement schedules vary according to water quality, household use, system design, and manufacturer instructions. The storage tank, faucet, tubing, and drain connection should also be inspected for leaks or sanitation concerns.

Some homeowners are comfortable replacing accessible cartridges themselves. Professional maintenance is helpful when the system has low flow, unusual tastes, continuous drain discharge, leaking connections, or declining water quality. A plumber can also sanitize the system, test the tank pressure, and confirm that the membrane is performing properly.

My brother’s apartment was flooding from a very old and non maintenance water heater. The property manager was not capable of getting a plumber there for an emergency that happened around midnight. Marybeth at Pro-Flo Plumbing was able get someone out there in a timely fashion. I’m grateful that they were able to remove the most of water shut off the water.

Pro Flo plumbing fixed two issues in our home that we had been putting off. The price was fair, our plumbers were outstanding and both jobs were done right.
Pro Flo also has now helped the nonprofit animal shelter my wife and I work with (APS Caswell) twice and did a great job for the shelter as well. When you go with Pro Flow, you can count on knowledgeable professionals explaining everything thoroughly, and getting the job done right for a reasonable price. I know my family are Pro Flo customers for life.

Paid this company for nothing! Told them the issue (disconnected pipe and clogged) the man claimed he climbed under the house and seen no issue then charged me a service fee but he didn’t do anything and I had to call another company out and they had the problem fixed within an hour and a new pipe connected.
