Watts (WQC4RO13-100MT) 4 Stage KWIK CHANGE RO System 100 GPD w- Metal Tank
4-Stage Kwik-Change RO System with Metal Tank
Four-Stage Filtration Process
Particulate Removal
The WQCSC11 sediment filter captures dirt, rust, silt, and suspended solids down to 5 microns, protecting downstream cartridges and the RO membrane from premature fouling.
Replace every 6-12 monthsChlorine and Chemical Reduction
The WQCCC11 carbon block filter removes chlorine, chloramines, taste and odor compounds, and volatile organic chemicals that would otherwise damage the reverse osmosis membrane.
Replace every 6-12 monthsReverse Osmosis Separation
The WQCM11-50 RO membrane operates at 100 GPD, rejecting dissolved solids, heavy metals, fluoride, nitrates, and microorganisms down to 0.0001 microns for water up to 2,000 PPM TDS.
Replace every 24-36 monthsFinal Taste Enhancement
The WQCGAC11 granular activated carbon filter polishes stored water as it leaves the tank, removing any residual taste or odor for crisp, clean drinking water at the tap.

No Sumps, No Mess, No Tools
Traditional reverse osmosis systems require you to unscrew housings with a wrench, spill water across your cabinet floor, and wrestle with O-rings during every filter change. The Watts Kwik-Change design eliminates all of that. Each cartridge locks into a manifold head with a simple quarter-turn twist, and built-in shutoff valves prevent backflow and water spillage when you remove a spent filter. Double O-ring seals on every cartridge ensure leak-free operation without hand-tightening guesswork. The metal storage tank provides superior durability compared to plastic or composite models, resisting corrosion and maintaining consistent pressure over years of service. Quick-connect fittings throughout the system make installation straightforward, and the WQA Gold Seal certification confirms that performance claims meet rigorous third-party testing standards under NSF/ANSI 58 protocols.
Residential Installation Requirements
The WQC4RO13-100MT is designed for municipal or well water sources with TDS levels up to 2,000 PPM and requires a minimum supply pressure of 40 PSI for proper membrane performance. The system fits in standard under-sink cabinet spaces and includes all necessary tubing, a dedicated RO faucet, drain saddle, and feed water adapter for typical 1/2-inch or 3/8-inch cold water supply lines. Replacement cartridges are model-specific: use Watts WQCSC11 for sediment, WQCCC11 for carbon block, WQCGAC11 for post-carbon,
