This one was a little funky to start - wasn't sure what was going on with the meter as it was cocked at an angle - these valves have to be plum or level to function correctly. Luckily the original pipe had been plumbed in a way that caused the meter to be pushed into this angle (weird !!!!) and I was able to dig the meter line out a little bit as well - and I got this think plumbed out just right !
Message us to get one of these handy little emergency gas shut off valves installed at your house !
