Purple lines only or you are in violation of health codes etc., not to mention you could incur another bill later on.

Actually the purple PVC is meant to identify underground irregation water lines. As long as you label your filter with Non-Potable Water you comply with code and will have no problem. If you really want to get crazy put a purple tape band on the filter as well.
Ferigator has been installing these filters for years and i've never heard of a problem.
