Express Water ROALK5D 10-Stage Alkaline Under-Sink RO System — 50 GPD, NSF 58 Certified, BPA Free, Deluxe Chrome Faucet

Pure, Alkaline Water Right from Your Kitchen

Express Water ROALK5D offers a true at-home purification experience with a 10-stage filtration sequence designed to tackle a wide range of common impurities. When water passes through the unit, contaminants such as chlorine, fluoride, heavy metals, and micro-contaminants are reduced, helping water feel crisper and taste cleaner for drinking, cooking, ice, and beverages. The system produces up to 50 gallons per day, making it suitable for daily family use without frequent restocking.

Beyond purification, the integrated alkaline stage adds minerals—calcium, potassium, and magnesium—into the final water. This mineral boost can subtly balance mineral content and enhance mouthfeel, making everyday pours and recipes more enjoyable while preserving the purity you expect from a filtration system.

Compact, DIY-friendly under-sink design

The unit is engineered to fit under most kitchen sinks. It ships with quick-connect tubing for straightforward installation and includes a 4-gallon storage tank with a stand. The deluxe chrome faucet delivers filtered water directly at the tap, so you don’t need to depend on pitchers or countertop filters.

Included items and installation tips

Everything needed for setup and the first six months is included: replacement filters, a filter housing wrench, quick-connect tubing, and a 4-gallon tank with stand. Uses standard 3/8" and 1/2" connections; plan for 40–80 PSI water pressure. You may require a booster pump or regulator depending on your water supply.

Note: For every produced gallon, the system discharges between one and three gallons, depending on pressure and incoming quality. This helps manage wastewater while you enjoy clean, great-tasting water at home.
