copper pipe problem

Can anyone help me fiure out why???

Copper pipe for HWBB in new house.
Heat was on for about a month, but the elbow broke and water was pouring out. Im wondering what the reasons are that it broke.

New copper hwbb with elbow. Broken part was by a sliding glass door, that was closed, and temp outside was 35 with 22 windchill. But heat was set to 60 in the house. Worked for about a month, and then broke.

the elbow had a bad mold and the seem ,separated do to expansion and contraction of the system .

Even a small draft hitting to pipe can cause it to freeze when the boiler is not running between cycles.

but the pipe was inside the house,, all windows and doors were closed.

A small draft can cause a pipe to break. I've seen brass ball valves crack from freeze ups.

I don't think so it may brake easily. find the reason lest it should break again. did you it install yourself? you should have taken help qualified professional, as i take from tucsonazplumbers.com/

Make sure all the air is out of the system.

the reason for your cpr line to break is because it frooze and split..either at the seam or the ice seperated the joint..reason being that is because when you heat water and make it hot your are releasing the oxygen molecules in it making it lighter.so in turn no oxygen in the water the the faster it freezes but the faster it heats as well

but the pipe was inside the livingroom. the elbow fitting came loose. The house temp was set around 60. So how could 60 degrees freeze?

My opinion is it must have been cold draft, aether the sliding door was cracked open or there is a opening somewhere for the cold draft to be aimed at that joint.
20F. ambient temp. will take at least 24+ hours to freeze a pipe, but a well directed cold draft will split a fitting or a joint in a very short time eaven in a
heated room. I've seen it many times. And Frank in Bayonne is correct. Hot water freezes before cold water, because it is less dense molecularly.Hope this helped.

the door was locked shut, and even so, the door opens on the opposite side from the pipe. So a crack would be 6 feet away.

Did you take apart the 90 and see if the solder had taken all the way around? Also, check your water pressure at one of your hose bibs. Also ask a neighbor to see if they have had any problems with water surges. If all else fails, put a digtal thermometer with memory in that location to find the exact temp.

Did you ever figure out what caused it, their was some great advice given by Roger and Frank that should have solved the problem for your plumbing fixtures. Let us know how it turned out.

If the copper was not insulated it will blow a the weakess place, if it is a joint it may had not been solder all the way, that is not uncommon. I grew up in Florida

the system is probably airlocked and needs to be purged.there should be purge valves close to the boiler.there maybe bleeders where is elbows down togo through the floor on the end of the baseboard. probably the heating system shut down and the elbow froze and broke. try bleeding the air out of the system and make sure that the circulator pump is running.

how does it freeze at 70 degrees?

A couple of things:
First of all if it is 35 degrees out side and the wind chill is 35 below zero it still will not freeze. It has to be 32 minimum. With the heater on, heat rises so even if you missed it by a few degrees this is probably not the case. There are only 2 real possibilities. First, and the one I would look at first is the joint may not have been soldered and blew apart. Sometimes a fitting will not leak if it had a lot of flux and the pipe was tied down and did not move around. If the joint was soldered even a little it probably will not blow apart. In all my years I have never seen that. It will leak before it blows apart.
I can not buy the bad mold at the seam because in order for it to blow apart it would have to be worked at for a while like bending it back and forth. It could do this with high surge lines but it would crack first in the seam and still be together for at least a while before it blew and then you would flood the house before it blows. I could tell just by looking at the fitting but I would say it was left unsoldered. I have seen it a lot.

did u leave the hose bib connecected? that will let the cooled air freeze and burest' your pipes
