Amazing what you walk into! We quoted and replace the boiler. If time went on and I was a builder we could of went in and quoted to replace the house. Glad no one was hurt.

A redundant safety relief device, now why didn't I think of that.

Fascinating...

Looks like no expansion tank and plenty of excercise for those T&P Valves. I'm surprised anything still worked down there considering how well those T&P valves "lubricated" everything liberally with water.

The after pictures look a lot better. I hope the HO appreciates the difference your install will make. In particular, I like the simplicity of a one-pump system and the attention to detail with the supply manifold, i.e. necking it down as you approach the last zone take-off.

I think this one did have an expansion tank

you can see what looks like the old one on the floor to the right of the new boiler.

But I see old hot-water systems without expansion tanks too frequently, especially in old Baltimore rowhouses. These things exceed 30 PSI in a flash when the burner starts. What a difference a #30 diaphragm tank makes.

Multiple relief valves,

So as I understand it, if that guy put on one valve you are safe, if he put a second one on to it, your are twice as safe, and if he put a third one on top of that, you are three times as safe, and so on.

So therefore the safety limitations on the installation of the relief valves on a boiler are negotiated by the ceiling height and how many valves you can pile up. Unless of course the service man gets resourceful and cuts a hole in the living room floor and just keeps on going, (for safety sake of course).

And hey, if the hole is in the right spot and the customer is REALLY REALLY REALLY safe, you can decorate that mess with balls and lights and use it upstairs as the Christmas tree .

Big Smile here,


BTW, that new boiler is really nice work, even if it has only ONE relief valve : )

Oil feed line?

I've never seen that type of oil feed line before. Is that something new on the market? What's it called? Approved in national or limited local codes? Looks soft and flexible... Never seen anything but copper so far.
