Features:- Manual Flush Valve allows user to increase membrane life - Clear micron cartridge housing makes it easy to view when cartridge should be replaced - Auto shut-off valve stops incoming water supply when outflow is turned off- Garden hose adapter makes it easy to connect to a garden hose tap - 1/4 inch Color coded tubing simplifies plumbing - 5ft of ¼” Blue, Yellow and Red Polyethylene Tubing helps with plumbing setup - Built-in wall mount bracket allows the unit to be hung and secured in place. Pre-Assembled Unit includes a 75 GPD Membrane, (1) 5-Micron Pre-filter Sediment Cartridge, and (1) 5-Micron Coconut Shell Solid Activated Carbon Block Filter Cartridge. OPERATING REQUIREMENTS: Minimum water pressure: 40 PSI, Maximum water pressure: 80 PSI, Optimal water temperature: 77*F (25*C), Maximum water temperature: 105*F (40.5*C).Typical rejection rate: 1:1.5 WHAT TO EXPECT:This RO system purifies 1 gallon of water every 20-24 min (very slow, water purification output depends on membrane Gallons Per Day rating, water dripping not flowing). RO membrane splits water with 0.0005 micron filtration, approximately 1000 times more effective than any water filter without membrane). We recommend to collect water in advance (every day or every second day) to always have it on hand. Use any kind of water container (glass or plastic). INSTALLATION GUIDE ON OCEANICWATER .

Perfectly. ### ⭐⭐ poor fitting low quality plastic, low quality filtration *by B***A on January 21, 2021* The good: Arrived quicker than expected, company is responsive, eventually KIND of works The bad: So much... Instructions suck, hard. They don't even mention you need to dissassemble the already assembled parts to remove the shrink wrap. They are just wrong on some parts Two parts don't actually fit, the hose adaptor and the RO membrane housing. Called the company the claimed other customers had no problems. After about two hours of attempts at teflon (and getting soaking wet as this is a pressurized system, did I mention it's winter? and getting soaking wet sucks) I got the RO membrane housing to seal, and gave up on the adapter. Went to home Depot, got a new adaptor. Got that to work with Teflon After an hour of flushing the system (and 3 hours of setting it up)it still only gets about 80% reduction in TDS :( The previous system I had cost a bit more but came ready out of the box and had 95% reduction in TDS (this promised 95% reduction, and said to replace membrane when it goes down to 90%...) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/111792990-3-stage-hydroponics-reverse-osmosis-water-filtration-system-75-gpd](https://www.desertcart.sk/products/111792990-3-stage-hydroponics-reverse-osmosis-water-filtration-system-75-gpd) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-26*
