I am looking to purchase a CPR 102 (has two 1" bulkheads) I read that two are better than one, just in case one gets clogged there is still water flow. Do I need to run both lines into the fuge separately , or can I "Y" them together and if so what size should the pipe be that they merge to. The fuge I am going to get has 1" bulkheads. Doesn't make sense to go from two 1" into one 1".
