I have PB plumbing unfortunately and today I heard a hissing sound and the drywall was wet in my garage where my main water line comes in. I cut the wall and found a pin hole leak in the top PB line right at the junction fitting spraying a thin line of misty water. I wanted to know the best way to fix this please and also confirm the top PB hose is 3/4 (incoming house water line)? I was going to get a sharkbite 3/4 PB to copper fitting and cut out the leak, put the sharkbite to the PB side but was not sure if the sharkbite can connect to the 3 way fitting tee directly or if have to replace the entire fitting tee (3/4 x 1/2 x 1/2) I believe. I appreciate any advice and guidance to get this done. Thanks Any help is much appreciated.
