Replacing my RO filters and wanted to add on the Remineralization Filter to balance the PH and improve the taste. In order to add this 5th stage filter to my 4 stage system it required purchasing the AC1 Kit. Upon receipt of this kit when trying to hook up the new filter I noticed that my system is setup for 1/4" tubing and couplings. I called Ispring Tech Support and was able to speak with Sean concerning my current configuration. Sean was very helpful and was able to provide me with the proper components to install the additional Remineralization Filter as a 5th Stage. Thank you Sean for taking the time to help get my system upgraded!
