Read the Check sheets it might say if the transit is less than an hour that a fuel water check is not required. Or needs 20 minutes for water to settle out of a refueled tank.
Modern aircraft have pipes that draw fuel from the lowest part of the tank by jet pumps and place the fluid near the inlet of the main booster pumps, so water does not build up past a few drops.
The daily check at main base might require a fuel tank water check to be completed, but then if a drain valve does stick open due to ice there is time to fix it.
