What is a CI trap?

Depends on climate and humidity, but in most areas a pint of water will easily evaporate in less than two days.

I have a bottled water on my desk that is a pint. The water at full in the bottle is a little over 6".
If in 36 hours it were to mostly evaporate, it would lose about 3/16" per hr. (You may check my math).
That does sound possible in very dry conditions. Am I right?
I live in Texas where it could take weeks.

Save
If it's been shutoff for months, it probably evaporated.

A few months back I bought a house to remodel. It was built on a slab in 1982 and was built to HUD specs. The bathtub was no good so I removed it and the P trap (which is cast iron) had been connected using a rubber sleeve. With the tub out of the way I thought I would pour some water down the trap to make sure it drained OK. No problem with it draining, however water only stays in the trap for a day or two. Water has been shut off at the meter for months so there is no siphoning effect taking place. Where is the water going?

I sssume the P trap is in the dirt. I would try to dig out around it. I bet you find moisture I. The dirt- a leak in the p trap is what I would be looking for
The suggestion of putting mineral oil in is good for a seldom used drain. Years ago we moved into a new a new retail location. Turned on the a/c and got a good dose of sewer gas. Called the guy that remodeled the place- we found a floor drain right under the furnace bathe blower would evaporate the water in the trap. Some veggie oil solved that problem

That might be difficult since the OP said the house is built on a slab.

The area around a bath drain is usually blocked out at least 10" square so that some access is possible. P traps fail on occasion and need replaced

According to this info, how long the water has been off seems irrelevant.
