Since Jon started it, how many of you are one? Many ways to tell if you are. You are on vacation but are fixated as to why the heck the system at the resort is designed the way it is. And you look in the valve box to see what valves they use. Did that in Snowmass this last weekend. Or driving down the road you see a geyser and it takes everything inside you to not stop and fix it. I've stopped and turned off an RP at a gas station when I saw water pouring out of a valve box and running down the street. I told the cashier to call the owner or lawn company about it, mainline broken. Never fixed it or turned it on again. The place looks like hell and is up for sale anyway. You are walking in the neighborhood and check out all the BFs on the homes and can tell which are not done according to code, or have been frozen in the past due to different ball vlaves, or repaired copper. You try to build something cool out of PVC parts. You keep all (most) the old timers you replace - just in case, now you have a ton of them at the shop and don't know what to do with them. In your dreams you are either installing or repairing systems What else??
