Pex Plumbing Question

2012 Sightseer, what size pex plumbing is there for the cold water line the ice connects to the T under the kitchen sink?

I have leak in the T, maybe snake bite connections. I'm not good at eye balling pipe size before heading to home Depot.

Anybody experience issues on that T connection? My first pex plumbing fix.

Most likely 1/2" pex. Before replacing make sure the pex is pushed in all the way to the fitting.

I'd look at the Watts AquaLock (formerly SeaTech) fittings.

If the ends of the tubing aren't cut perfectly square they can be a source of leaks.
Good suggestion to try to push in as sometimes thay aren't fully seated and initially seal but do loosen up.
