Home › Forums › Other › OT: Slab leak burst pipe solutions › Is the island a original
Is the island a original builder install or an add on remodel item?
Remodel job may have cut the slab and used plastic pipe(PEX). Easier to fix than thru slab piping.
Do you have an additional kitchen sink? If so, cap the hot water to the island and just run cold.
Re-piping the whole house is probably not necessary. Just the failed section.
What exactly ‘burst’? Is it a fast leak, or seepage? If slow leak may look into epoxy coating the interior.
