Wood Master 4400 Broken Water Line

Hello,

I am new here looking for some help.... I have a Wood Master 4400, one pump runs 24x7, the other pump is on a timer and runs for 30 minutes and shuts off for 90 minutes. Well... my timer failed the other night when the outdoor temp got down to 11 degrees. I got up in the morning, realized the pump was not running, turned it on and water started coming out of the back of the stove. So I turned it off, went out and removed the back cover and had the wife turn the pump back on so I could see where it was leaking. The return line above the ball valve is where the line broke. I put my hand up behind the insulation (Red Arrow on pic 2) to feel around for a broken line, and the metal ring in the attached picture fell out. I can't find a picture anywhere that shows the back of one of these stove without the insulation. So I don't know what this fitting goes to. I'm not sure what actually broke. It looks like a major operation to get to this location. Any ideas? Thanks....

The metal ring was part of a Sharkbite Fitting that had broke, the brass barb was still in place so I was able to reconnect the PEX to it using a Pinch type ring. I would have never been able to fit a crimp ring tool in that small space. Now I gotta go tape up the insulation I had to cut.

I'm a little confused. It looks like the lines should have been connected to the fittings at the bottoms of the valves? Not sure why a connection above those valves under the insulation? I must be missing something.

The lines coming from the house go into the bottom of the valves. Out of the top of the valve is 2' of PEX going to a elbow (Sharkbite in this case) going into the water jacket.

Switch to glycol if you have water in the underground lines.Just imagine what will happen if the power goes out when you arn't around to get auxiliary power going.

I may go to glycol next year. As far as aux power, I have a automatic transfer switch.
