This 88 year old home had a home made piping system installed at the basement sub floor that I am trying to figure out what they were doing.
One end was not connected. The other end was at the band/sill plate.
It looks like garden hoses covered with rubber.
There was a 240 volt circuit nearby. There is no A/C system installed.
I really have no clue!! Do You??
I would guess home made lines for some type of cooling system.
