Enjoy Refreshing Water with Sterling DWSB-TFC-50 50 GPD Reverse Osmosis Drinking Water System Get bottle-quality water right at the sink for cooking, coffee, ice, and everyday drinking. The Sterling DWSB-TFC-50 is a 5-stage under-sink RO that reduces dissolved solids and improves taste and odor, finishing with a post-carbon polish for a fresh, clean finish. Sized for typical households, the 50 GPD TFC membrane pairs with a compact storage tank to keep water ready on demand. Maintenance is straightforward with standard 10″ cartridges and quick-connect fittings. Brand: Sterling Water Treatment MPN: DWSB-TFC-50 Type: 5-stage under-sink reverse osmosis (RO) drinking water system Size/Capacity: 50 GPD membrane (typical production varies with pressure/temperature/TDS) Material/Finish: Aluminum bracket; standard 10″ filter housings; TFC membrane; pressurized RO tank Performance: 70–95% TDS rejection (max feed TDS 800 ppm); feed water temp 40–100 °F; recommended feed pressure 40–100 psig Connections/Fit: Under-sink install with RO faucet kit; 1/4″ OD tubing with quick-connects; feed saddle valve and drain connection included; optional icemaker hookup Dimensions: RO assembly approx. 16″ W × 20″ H × 5.5″ D; storage tank approx. 10″ dia × 15″ H Included: RO assembly (sediment + 2× carbon pre-filters, RO membrane, post-carbon), pressurized storage tank, faucet kit, tubing, feed valve, drain clamp Certifications/Compliance: Use on microbiologically safe water; see manual for operating limits and local code requirements Warranty: Limited manufacturer warranty (see Sterling terms) Save Water & Improve Taste A thin-film composite membrane reduces dissolved minerals, while the final carbon stage polishes taste and odor. With a 50 GPD rating and 70–95% TDS reduction, you’ll notice cleaner flavor in beverages and clearer ice for everyday use. Everyday Performance You Can Feel Sized for typical households, the system keeps a pressurized tank of RO water ready at the faucet. Expect best performance with feed water within the published limits (40–100 psig, 40–100 °F, <=800 ppm TDS), helping ensure steady flow and quality. Durable, Serviceable Design Standard 10″ sediment and carbon cartridges protect the TFC membrane and are easy to replace on a regular schedule. The aluminum bracket and proven components support long service life under the sink or in a nearby basement location. Installer-Friendly Kit Everything needed for a typical install is in the box: faucet, tank, feed saddle valve, drain clamp, and tubing with quick-connect fittings. An optional icemaker tee can be added for chilled RO water at the fridge. Sized Right For Tight Cabinets The compact manifold (16″ × 20″ × 5.5″) and tank (10″ × 15″) fit neatly under most sinks. If mounting in a basement, plan a clean tubing run and leave clearance for filter changes. Know Your Water & Limits For best results, feed water should have < 7 gpg hardness (or be softened), < 0.1 ppm iron, < 0.05 ppm manganese, and no hydrogen sulfide. Use only on potable water; pre-treat if your source is outside these limits. Simple Upkeep, Low Cost Replace pre-filters per the manual (often ~6 months, site-dependent) to protect the membrane and maintain flow. The post-carbon “polish” filter is replaced when taste changes or on schedule—no special tools required.
