I'm finally getting around to replacing my irrigation systems back flow safety and had a question or two.
Originally I had two atmospheric valves on my irrigation supply line. I've now bought a pressure vacuum breaker. I have everything pieced together and ready to solder.
1) The old setup was all soldered together, no easy break down. I had to cut an elbow to get everything off. Does it matter if I solder it all together again or should I put a coupler in there?2) Assuming I just solder it all together as is how will teflon tape on a threaded male adapter hold up to the heat of soldering the other end of the same adapter?
Thanks Matt
