Watts-GTS550S-NAGF-MT Watts GTS Series 5 Stage Standard Cartridge Reverse Osmosis
System Details
| Model Number | Watts GTS550S-NAGF-MT |
| Filtration Stages | 5-stage reverse osmosis |
| Membrane Capacity | 50 gallons per day (GPD) |
| Membrane Filtration | Down to 1/10,000 of a micron |
| Storage Tank | 3 gallon metal pressure tank |
| Faucet Type | Non-air gap reverse osmosis faucet |
| Recommended Inlet Pressure | 40 psi |
| Maximum Water Hardness | 15 grains per gallon (GPG) |
5-Stage Purification Process
Removes dirt, rust, and particulate matter to protect downstream filters
Reduces chlorine, taste, and odor compounds from municipal water
Secondary carbon filtration for enhanced chlorine and organic removal
50 GPD membrane removes TDS, lead, and contaminants down to 1/10,000 micron
Post-filter refines taste and ensures fresh water delivery from storage tank
Setup and Maintenance
- Mount the system under your kitchen sink with adequate clearance for the 3-gallon metal storage tank and filter housing access
- Connect the feed water line using the included quick-connect fittings, ensuring inlet pressure is at or near 40 psi for optimal performance
- Install the non-air gap faucet through a countertop or sink hole using the provided hardware
- Allow the system to flush for the first 2-3 tank cycles before use, then replace sediment and carbon filters every 6-12 months depending on water quality
- Replace the 50 GPD reverse osmosis membrane every 2-3 years or when you notice a decline in water production or quality
Water Source Requirements
The Watts GTS550S-NAGF-MT is designed for municipally treated water supplies with water hardness up to 15 grains per gallon. If your water exceeds this hardness level, consider installing a water softener upstream to extend membrane life and maintain system efficiency. The system requires a minimum inlet pressure of 40 psi to achieve rated flow and filtration performance. Use only genuine Watts replacement cartridges to maintain warranty coverage and ensure consistent filtration quality across all five stages.
