Sprinkler valve replacement mistakes to avoid and tips.

What is PTFE and pipe dope?   How do you use them?  When solenoids buzz, check the white "common wire" group and make sure  wires are not freyed and each wire is properly touching each other, twist on the wire nut snuggly, but dont overtighten.

I suggest 4 or 5 wraps with PTFE to be sure.  And if you want total confidence of no leak, you can add a pipe dope bead on top of the PTFE, all the way around the threads.  Good Luck!
