no heat call

Friend wanted me to look at a no heat on a house with a boiler. Vacant, being worked on. Go to a late model Series 2 and hear water running. Look at the tridicator. 50 psi. Wow. Looked at the yellow handled ball valve in the picture. WIDE OPEN. I shut it, in a minute down below 20 psi so I fired it up. Both loops heated up, all baseboard getting hot. Wonder how long it had been running like that? They'll know by water and gas bill!

    Exactly what I would like to know. Out the relief valve I guess

    LUCKY ......Sounds like relief went to a sewer line.

    Mine was aimed at floor, only got a 5 gal bucket when I noticed OLD relief started weeping. But my fill valves are kept off, I want to know what it's doing.

    There doesn't appear to be a back flow preventer in the system or at least not in the picture.
    Was the relief actually working???

    Relief piped to crawl space, very wet down there :) Most don't use backflow preventers around here, Jobs rarely inspected. We do.

    Relief to sewer ....... thinking about it that wouldn't be such a great idea if it blew on hot & pressure....... while you were sitting...... answering the call of nature.
