Model SY2000 vs EZ system-Filtration 4

[desi78]

Please tell me the diffence between model SY2000 and EZ system-filtration 4. Which is the simpliest to install?

The Culligan SY-2000 is no longer available. Culligan has replaced the SY series systems with the EZ series systems. The EZ series are easier to install and also easier to replace the filters. The US-EZ-4 also reduces more contaminants than the SY-2000 did. The US-EZ-4 is located here:
