Frequently Asked Questions

A reverse osmosis system forces water through a semi-permeable membrane under pressure. The membrane allows water molecules to pass through while blocking dissolved solids, heavy metals, chlorine, fluoride, nitrates, and other contaminants. The filtered water is stored in a small tank under the sink and dispensed through a dedicated faucet. Rejected water and contaminants are flushed down the drain.
A properly functioning reverse osmosis system removes chlorine and chloramines, lead, arsenic, nitrates, dissolved solids, fluoride, certain pesticides, pharmaceutical residues, and many other contaminants. The exact removal percentages depend on the membrane quality and the maintenance status of the pre and post filters.
Pre-filters and post-filters in a reverse osmosis system are typically replaced every six to twelve months depending on your water quality and usage volume. The RO membrane itself is typically replaced every two to three years. Following the replacement schedule maintains system performance and protects the membrane from premature failure.
Yes. A reverse osmosis system requires connections to the cold water supply line, a drain connection, and installation of the storage tank and dedicated faucet. Incorrect installation can result in leaks or reduced system performance. Downey Plumbing, Heating and Air Conditioning installs reverse osmosis systems completely and tests water flow and system function before leaving. Call [phone] to schedule RO installation.
Most under-sink reverse osmosis systems can be installed in any kitchen that has a cold water supply line and a drain connection accessible from under the sink, and that has space under the sink for the storage tank. Our technicians confirm installation feasibility before beginning any installation.
Standard reverse osmosis systems produce wastewater as part of the filtration process, typically flushing three to five gallons for every gallon of filtered water produced. Higher-efficiency systems and permeate pumps can reduce the ratio significantly. Our team can advise on efficiency options during the installation consultation.
Reverse osmosis water tastes clean and neutral because virtually all dissolved minerals, chlorine, and other taste-affecting compounds have been removed. Many people find RO water tastes better than both tap water and most bottled water. A post-filter re-mineralizer can add trace minerals back if preferred.
Yes. Reverse osmosis water is safe to drink and is produced by the same technology used in many bottled water brands. The filtering process removes a broad range of contaminants while leaving pure water molecules to pass through.
Yes. Many homeowners connect their RO system to the refrigerator ice maker and water dispenser so that all drinking water from the kitchen is filtered. This requires running a small supply line from the RO tank to the refrigerator. Downey Plumbing, Heating and Air Conditioning handles this connection as part of the RO installation or as a standalone service. Call [phone] to discuss refrigerator connection.
A standard carbon filter removes chlorine, some VOCs, and particulate matter, improving taste and odor. Reverse osmosis goes significantly further, removing dissolved solids, heavy metals, nitrates, and a much broader range of contaminants that carbon filtration does not address. RO is the more comprehensive solution for homeowners with serious water quality concerns.
Residential under-sink RO systems typically produce 50 to 100 gallons of filtered water per day depending on the system capacity and incoming water pressure. This is sufficient for all drinking and cooking needs in a typical household. The storage tank holds filtered water ready for immediate use.
The RO storage tank is pre-pressurized and generally requires no regular maintenance beyond keeping the system connections clean and sealed. If the tank bladder fails, the tank may hold less water than expected or fail to deliver water at adequate pressure. Our technicians check tank pressure during filter replacement visits.
Yes. Downey Plumbing, Heating and Air Conditioning services and replaces filters in reverse osmosis systems regardless of brand or who originally installed them. Call [phone] to schedule RO filter replacement or system service.
Yes. Fluoride is removed by a properly functioning RO membrane at a high percentage, typically 85 to 95 percent removal depending on the membrane quality and operating conditions. If fluoride removal is a priority, discuss membrane specifications with our team during the installation consultation.
Downey Plumbing, Heating and Air Conditioning provides upfront pricing before any work begins. Call [phone] to schedule an RO installation consultation and receive a clear estimate.
