Frozen Pipes in attic space
My Mother-in-law lives in a suburb east of Cleveland Ohio in a ranch on a slab. When they added on a kitchen back in the day, the pipes were run through the attic. The pipes freeze up each and every winter and they burst about 3 years ago destroying the kitchen. She can not get up in the attic any longer and my Father-in-law passed away 8 years ago. After the problem 3 years ago, a plumber added heat trace to each pipe coming from the water heater and wrapped them in insulation. Would it help any by building an enclosure around the pipes and insulating within that or would that be a waste of time. What about re-running piping with PEX under the flooring. I am trying to think of other options to help out and that lead me here to see if anyone has suggestions. I attached a few picks that were taken after the plumbers work.
Thanks in advance for any help. Allan
