I have a 2300 sq ft unfinished basement that has a hydronic radiant heating system. I want to add an in-law suite with 2 bedrooms and 2 bathrooms and a kitchen. Cutting into concrete containing PEX tubing is obviously problematic. I could use flush up systems but putting showers or tubs on risers doesn't appeal to me. I want the plumbing done right and I don't want to destroy the radiant heating system. Replacing the radiant heat with forced air would be a last resort. I know PEX can usually be repaired but can it be after it's been cut through in concrete? I welcome any ideas and suggestions on how to proceed without destroying the radiant heat.
