Recently moved into a mid 70's built house in south Texas. The house was plumbed for a water softener with the connection in the garage.
Evidently this was a planned event as the structure has exterior spigots for both softened and regular water.
Am concerned by the lack of a drain anywhere in the garage. Would a drain not be required 10, 20, 30 years ago? Might there be an alternative method?
Seriously considering adding a water softening system to the house. Any dangers doing so after a previous unit that was removed perhaps decades earlier?
