Plumbing question -- joining 3 primary lines together

Thanks....I'll take a look at the Sharkbite stuff. I did find a 3-way 1/2" tee at a local plumbing supply place that I'm going to pick up tomorrow. That will be the easiest fix. Going the Sharkbite route means I'll have to convert over to PEX or something that works with those connectors -- so I'll save that for a future project.

Thanks a bunch.
