 Re: instapure model IF-3OU now IF-35?
The IF-35 replaced all the Waterpik inline refrigerator filters. It actually replaces your entire unit so the IF-35 is installed in place of everything you have now including the fittings. So, it does not matter that it looks a lot different since the whole thing is replaced. It is installed on a ¼" line.
I hope this helps! |
