If you have any problems later with this valve, it will be your nickel.
The exhaust tube runs about 100' to a Richdel 205. Not sure were the 205 is sending the water to. The reason I don't want to reroute is the roots have grown solid around the piping. I'm talking the size of your leg. True it's just a matter of time before the roots win over the copper. This tree is 3 to 3 1/2' diameter. If I can get a rebuild to go a few years it will outlast the owner and this place will be a tear down for a mac mansion with the next owner. This is why you should keep the main and valves far away from trees. Even small trees become big trees. I was on an install I did twenty five years ago this week and saw the same thing happening. Tree roots pushing the main and laterals around. That tree was little when I installed the system. My valve was a good six feet from the tree and now is totally encased by roots.
