@beenthere... That's the only water feed on the system.
Yup. One prv will fill you furnace and keep it from over filling. You can't accuratly fill the boilr with that hand valve. The back flow preventer is code. Its a good idea. If you loss city water pressure, the water backs up and diverts to the floor.

How did you drain the boiler?

The pipe split because you possibly over tightened a tapered pit fitting. You can find a chart for tightenig pipe on line. 3-4 turns by hand and make up 2-3 with wrench. Some where around there.

One thing i metioned befor was isolating with ball valves. One exception, do not do the pressure temp valve. If you close it a forget bad things can happen

That C Clamp has been on for the longest as well.
Just took this pic & somehow it's refilling? This is driving me crazy because the feed is turned off so don't know when the water is coming from?!

You hand valve might be leaking. Is the pressure rising or falling.

Water is probably slowly leaking through the valve.

O by the way, i have never seen a male pipe slpit. Looks like msle
Ipe was replaced. Secondly, support the other pipes attached to the furnace when removing bacause you can snap them off the furnace= new furnace.

The pressure on the gauge rises past 30 that's when it starts leaking, but as stated earlier that top piece has a split in it.

That's alot of water refilling just for a leaky valve? We're talking about over 5 gallons?

Yes I'm going to replace that section today.

Does it leak out the valve or the split in the pipe?

Out the valve your hand refill valve is leaking and city water pressue is making it into a closed system. Read tha valve pressure releif settings. City water is around minimun 60 psi. Valve should be around 30. You will have a constant leak if the hand valve is leaking. Shut off city water at meter and see if that helps. Relive pressure through out the system. But watch your water heater. Don't want to heat an empty tank.

This is why you nee a prv. It should keep pressure in boiler happy. Around 20 psi. Now take a full system with a full expansion tank. Where is the expanded water going to go, out th press/temp (pt) valve. Put an elbow an drain pipe on the vavles for both your water heater and boiler.

You would be suprised how much a drip can accumilate to. Check out attach in next post

So can just put a regular pipe on there then reduce it to fit the pressure valve?

On where? If you mean reducing valve goes in line with city water after back flow. Simple picture coming

Ah. So you didn't drain your system. You tried to drain your expansion tank, I guess.

If you tried to drain your expansion tank. And left the water run out until it stopped. And then closed the drain valve. It didn't drain fully. Unless you opened a air vent to allow air to be drawn into it while it was draining.

The pipe coming out the side of the boiler that was said to look like a missile.
Duplicate those connections exactly?
