“Don't know why, but both type L and type M tubing was "loose" in the ports. I took the valve apart to solder it because of the heat required to heat the thick brass. I was able to make a tight seal even though the pipe wasn't snug in the port as it should have been. Tip - use a small C clamp to hold the valve in place when you screw the plate back on after soldering, it's much easier to compress the spring that way. Besides that issue, valve works flawlessly.”
