Most Unusual Things I Have Come Across Inspecting

Most Unusual Things I Have Come Across Inspecting
Plumbing. Waste Water.

Location; Basement.
2" Gray water back float valve.

Terracotta gray water drain pipe supplying/dispersing gray water into a catch water basin located in the basement of a 1960 home located near a river.

The concrete catch water basin had a back ‘float’ valve.
The valve consisted of a rubber ball mounted inside a cast iron pipe with a steel rod attached at the top of the rubber ball.

The ball valve is held in position with a brass collar affixed to a cast iron waste pipe, I suspect.
The protruding steel rod was affixed/attached with screws atop the rubber ball, encompassed by a steel spring acting as a counterweight support so the ball could move in a vertical position atop flowing water.

Very common for basement drains.

I must be mistaken.

Do you have any images to share like mine, or anything unusual for Canadian residential buildings?

Best.
