Sump Cover [Reloctated thread]

I need to purchase a radon sump cover. When searching for a cover, do I measure the inside diameter of the sump pit when searching for a cover? For example I see 24" mentioned for some sump covers but I don't know if that is inside diameter or some other measurement.

The inside of sump liner diameter is ~17.5".
My current sump cover is ~18.5" in diameter
The sump pit liner itself looks to be ~20" in diameter if measuring the top outer lip that touches the floor cement slab

Most of the covers come in 16", 20" and 24" sizes.

You will probably need to use a 20" cover.
