Very poorly assembled. Both connections were leaking. I had to disassemble both, replace the o-rings as they were deformed and didn't work. Also, there is a small vent at the top, two of mine were leaking, I installed mine under a non-meter meter and could only see water leaking from the top before removing the entire unit. Changes a star like a plumber, the thing won't stop leaking even if you screw the fittings on so no threads are showing.
