How to tell if a pipe running through a cinder block wall is leaking

freezingpipe

I ran a cpvc pipe through a cinder block exterior wall to put a spigot in. I don't really have access to the inside of that painted cinder block wall where the pipe enters the cinder block. It just got really cold here and I forgot to cut the supply of water to the spigot from the inside cut off. I turned on the spigot and nothing came out. The spigot is sealed around it with caulk.

Basically I think my pipe froze and thawed but I'm not seeing any signs of leaking. How can I know if it is actually leaking?

Turn off all faucets, and devices in the home that might use water. This includes, but is not limited to ice makers, dishwashers, clothes washers, faucets, running toilets, etc.

Use a little piece of tape, one of those "sign here" stickers, or something similar to mark the water meter reading (or if it's digital, just write down the reading). Don't use any water for an hour or two, then go back and check the meter. If it's changed, you either have a leak, or forgot to turn something off that used water.
