Hello, Thank you for using this service, I will be helping you with your problem today
okay if this is the bladder for yours and the small crack in the line is far enough to splice they sell quick connect couplings for the repair, this is your bladder correct ? if you go to lowes they sell quick connect couplings, you just cut the bad section out and slide the lines in each end, very simple and very cheap. ask for a 1/4" quick connect for a plastic water line. hope this helps. the bladder is not under warranty , sorry.
this will not void any warranty we have left will it ?
