Reverse Osmosis System Question
I have a Water Factory 4000 TFCM HF SO system and it has been disconnected for close to 5 years. The tank is around 2 to 3 gallons but it was standing in some water from time to time due to a leak that was near where it was stored (inside). It has developed some rust on the bottom. Which would be the safest and cheapest thing to do? Should I just buy replacement filters and hook it up? Should I buy replacement filters and replace the tank then hook it up? Or should I just buy a new system? My concern about the tank is if there is any corrosion in the tank since it was never truly emptied. Also, do I need to replace the membrane that holds the carbon or just replace the carbon in the plastic piece? Any help would be appreciated.
