A few years ago, I had a second tank added for a backup generator on the opposite side of my home. I was told it was my job to monitor it , and I was fine with this. BUT, your guy, each time he comes, checks this tank and fills it when it's needed. I did not ask for this, and I know he doesn't have to do this, but does. All on his own. I still keep an eye on it, just because :). But it's nice to know that this was done(several times now) without me really having to do anything. Thx to your team who does this work
