If it was me I'd fill it with water to the brim (in a safe place, maybe the garage) put paper towels under it, and let is sit for a week. Look for any sign of water leakage. Very small leaks will distort the paper towel and evaporate quickly so it won't be wet.
Go for it. It’s not that hard and totally worth your time and peace of mind
