Not having any idea how the other piping is run leaves me at a disadvantage, however it might be possible to abandon that set of piping and run new lines using PEX which can be fished and snaked where other rigid piping will not work. There should be enough space under you cabinets for new lines, but it might not be accessible either. The violated the first rule of plumbing, "never run water lines in exterior walls" but it is a bit late now. PEX can also freeze without fear of rupturing.
When we put s window in front of the barn doors, they ran the water pipes from the inside wall around to the sink under the window. Roughly 10'. They built out a 6" wall and insulated from the outside in. Form core board, then R19 batt, before the outside wall was put in place. The inside was sheet rocked, before the cabinets were installed. So no exposed pipes. And we close the barn doors at night, covering the window and the area below. But, last night with temps below 2degrees and wind chill -4, the pipes froze. Just the one in the kitchen sink area. Water in the rest of the house working fine. We simply forgot to leave a faucet running, which might have helped.
We have the exposed pipes in the barn covered with insulation and heat tape, but different person did the kitchen pipes. I've got heat running under the cabinets, but it's been almost two hours now and no water coming out - but neither is there any water coming out from under the cabinets inside or out, which might indicate a broken pipe. We can cut the back of the cabinets out and insulate the pipes, but I'm wondering if there is a better/easier way to accomplish the same thing. The way the cabinets are installed we'd have to cut out at least four cabinets. The alternative would be to pull off the outside siding and add something from that area.
Thanks for any thoughts.
