In a temperate climate I doubt it would take more than 5-10 minutes at most for the valve to fully open. Visually, you can tell if it opened by seeing if the weight changed from being almost horizontal to hanging downward. The spring should have almost no tension when at temperature and you can freely move the weight up only to have it fall downward again when you let it go.
The exaust will eventually come out the drivers side but maybe at a slightly smaller rate than the passenger side because of the slight restriction provided by the valve. Water drops are somewhat normal during warmup and will even come out the end of the tailpipe to drip on the chrome bumper end. Many have installed a short chrome tip extension so the drips are a bit farther out so as not to damage new chrome plating.
If when the valve is seen to be fully open and the exhaust on the drivers side is still not very strong, it is possible the muffler or resonator has rusted internally and is partially blocked or it is even possible some critter has set up housekeeping somewhere in the exhaust if the car sat for a long time. A restricted exhaust could also have something to do with low vacuum readings.
Mice do like to build their nests in the darndest places.
