Yep. A failed spider gasket can let water go everywhere.

PS. Replacing a spider gasket successfully is tricky, and none of the aftermarket glues to hold the gasket in place work like the OEM stuff. Consider replacing the valve if that's not too hard. If you clean the channel the gasket rests in very carefully, clear silicone will probably hold the gasket in place for a season. Do NOT use too much. If "Waste" sees this thread, he may have a better suggestion.
