African violets are susceptible to crown rot and water spots on leaves so it's best not to water from above or get any water in the center of the plant. You can water carefully below the outer leaves. Also, there are pots available for plants that need to be watered from below where the water goes in near the base of the pot and is absorbed by the soil. You can do it yourself by setting your potted violet inside a larger pot with water till the soil has absorbed sufficient water. Here are details:
