Reverse Osmosis Accessories
Replacement faucets, storage tanks, and osmosis accessories for your RO system. Universal compatibility, quality finishes, shipped to your door.
The Replacement Parts That Complete Your RO System
Your reverse osmosis system’s water filter, carbon filter, sediment filter, carbon block, and RO membrane handle the water treatment. But the faucet and tank are what deliver that reverse osmosis water to you. A cracked tank loses air pressure over time, which means slower fill rates and inconsistent flow. A worn or corroded faucet can reintroduce contaminants right at the point of use, undoing the work the rest of the system put in. Both are straightforward reverse osmosis parts to replace, and doing so keeps your drinking water system performing the way it should.
We carry reverse osmosis accessories that fit EcoWater, 3M WaterFactory, and most other common residential RO systems and house systems. Whether you need a new faucet, a replacement tank, or other osmosis accessories, the parts below are compatible with standard under-sink setups.

Reverse Osmosis Faucets
We stock non-air-gap RO faucets in two finishes: the WROF1-BN in brushed nickel and the WROF2-CHR in chrome. Both are standard-mount designs that fit most residential reverse osmosis systems, including EcoWater, 3M WaterFactory, and other under-sink drinking water systems. The faucet mounts through a standard countertop hole and connects directly to the RO system’s output line.
Replacing a faucet takes about 15 minutes with basic hand tools. If your current faucet is stiff, leaking at the base, or showing visible corrosion, a new one restores both the look and the function of your filtered drinking water dispenser.
The WROT3 is a 3.2-gallon reverse osmosis storage tank that is universally compatible with all EcoWater RO systems and fits most other residential under-sink setups. The membrane housing feeds filtered water into this pressurized tank so it is ready when you turn the faucet on. Over time, the internal bladder can lose air pressure or develop leaks, and a simple pressure gauge check will tell you whether the tank is holding properly.
If your RO system seems to be producing water but the faucet delivers a weak stream that fades quickly, the tank is the likely cause. Replacing it restores normal flow and ensures the system is storing its full capacity between uses. Homeowners who also run a water softener, UV lamp system, or other filter housing alongside their reverse osmosis system should check the tank whenever they service those components.

When to Replace Your Faucet or Tank
RO faucets and tanks are not on the same filter replacement schedule as your osmosis filters and membranes. They last for years under normal use. Replace the faucet when you notice leaking, stiffness, or visible wear. Replace the tank when water flow slows despite fresh replacement filters, or if a pressure gauge shows the bladder has lost its charge.
Never Miss a Filter Change
While faucets and tanks have long service lives, the filters and reverse osmosis membrane inside your system need regular attention. Our AutoShip program delivers compatible replacement filters and drinking water filters on a recurring schedule, so the entire drinking water system stays in working order.
