An 8 year old iSpring undersink reverse osmosis water filter.
This is a 6 filter system (the standard 5 states plus an akaline filter).
Includes tank, water faucet, and tubing.
I am giving it away for use as parts.
The first three filters are about a month old, the reverse osmosis is about 6 months old.
About a month ago it developed a pin hole leak in one of the filter housings.
Rather than try to fix it, I replaced it with a different system.
Hence, I have no need for the filters.
If you are ambitious you could fix the pin hole leak. Or put it somewhere where a constant drip does no damage.
