Drinking Water Systems in Janesville, WI

If you install whole-house filtration, you may still need RO. A whole-house sediment or carbon filter may address different concerns than RO. Many homes use whole-house treatment for general water quality and point-of-use RO for drinking and cooking.

You should contact a water filtration professional to size a water filtration system for your home.

You should call a professional reverse osmosis installer because correct installation requires suitable water pressure, drainage, tank placement, tubing, filter access, and any necessary pretreatment. A professional will also be able to follow local plumbing requirements, test the completed system, and reduce the risk of leaks or poor performance.

Use the replacement interval listed in the manufacturer’s manual or ask Addie which schedule applies to your system. Reduced flow, slower tank refill, or changes in taste and odor may also indicate that replacement is due.

Many RO prefilters and postfilters require replacement every 6 to 12 months, but the manufacturer’s schedule takes priority. The featured FreshPoint GRO-475 specifies annual prefilter and postfilter replacement, while Microline calls for its sediment/carbon prefilter to be changed every 6 to 12 months under the conditions in its manual.

There is no universal replacement interval for a whole-house RO membrane. Water chemistry, pretreatment, pressure, usage, and scaling or fouling all affect membrane life. Follow the manufacturer’s guidance and use changes in production or dissolved-solids rejection to help determine when replacement is necessary.

Carbon filters primarily reduce chlorine and substances that cause unpleasant tastes or odors. The carbon prefilter treats the water before it reaches the RO membrane, helping protect the membrane from chlorine damage. A second carbon filter treats the water after it leaves the storage tank to improve its taste before it reaches the faucet. Some carbon cartridges can reduce additional contaminants, but those capabilities vary by product.

Yes, an RO system can be installed on well water, provided the well water is potable and meets the system’s operating requirements. If your well water does not meet the RO system’s requirements, pretreatment can help you get there.

If your reverse osmosis system stops producing water, confirm that the cold-water supply and tank valve are open and look for an obvious kink or leak. If production does not return, call for service. Clogged filters, low pressure, incorrect tank pressure, a fouled membrane, or a valve problem may be responsible.

RO water can probably be connected to your refrigerator. Compatibility depends on the system, tubing route, distance, storage capacity, and available pressure. Addie can determine whether your refrigerator dispenser or ice maker can be connected to your RO system.

Reverse osmosis is a filtration process that forces water through a specialized membrane. The membrane allows treated water to pass through while rejecting many dissolved minerals and other substances, which are flushed to the drain with a separate stream of water. Most residential RO systems also use sediment and carbon filters to protect the membrane and improve the water’s taste and odor.

RO can greatly reduce certain PFAS, but the claim must be verified for the exact system.

PFAS are a large group of long-lasting synthetic chemicals, and PFOS is one chemical within that group. Depending on the compound and equipment, granular activated carbon, ion exchange, and reverse osmosis may reduce PFAS.

Yes, you still need to boil water if you have RO during a boil notice unless the public-health authority that issued the notice specifically says otherwise.

Installing RO will not necessarily require drilling into your countertop. Your installer may be able to use an existing sink-accessory opening. If no suitable opening exists, a hole in your countertop may be needed for the dedicated faucet.
