Good evening and thank you in advance for replying to my first post! I didn't have to worry about plumbing issues until now that I bought my first home. Anyways, I am trying to install no freeze silcock. The main water line is 3/4" PEX. I put T connection with 1/2" PEX line going to the silcock. The problem I am having is that the silcock is leaking from what appears to be brass connector. It does not leak from the PEX line end. Replaced the connector, it sits tight with teflon tape but still leaks. Thank you!
